Daravair-1000 is a clean, light-orange produd designed to generate specificationcluali air systems. Based on a high-grade saponiYied rosin brmulation, Daravair-1000 is chemically similar to vinsol-based products, but with increased purity and supply dependability. Uses Daravair-1000 may be used wherever the purposeful entrainment of air is required by concrete specifications. Formulated to r- form across the entire spectrum of pr~u~ion mixes, Daravair-1000 generates quality, freeze-thcr,,v resistant air systems in concrete conditions that include the following: · Low Slump · Paving · Central Mix · Extruded Slip Form · Mixes Containing Hot Water and Accelerators * Precast · High Cement Factor ', Fly Ash and Slag · Superplasticizers · Manufactured Sands Air-entraining Action Air is incorporated into the concrete by the mechanics of mixing and stabilized into mil- lions of discrete semi"rnicroscopic bubbles in the presence of a specifically designed air- antraining admixture such as Daravair-1000. These air bubbles act much like flexible ball bearings increasing the mobility, or plasticity and workability of the concrete. This can rmit a reduction in mixing water with no 'oFo~ of, slump. Placeability is improved. Bleeding, plastic shrinkage and segregation are minimized. Through the purposeful entrainment of air, Darovair-1000 markedly increases the durability of concrete to severe exposures particularly to freezing and thawin . It has also demonstrated a remarkable cr~oility to impart resistance to the action of frost and deicing soils as well as sulfate, sea and alkaline waters. Compatibility with Other Admixtures Daravair-1000 is fully effective and compatible in concrete with other admixtures. EACH ADMIXTURE, HOWEVER, SHOULD BE ADDED TO THE CONCRETE SEPARATELY. Addition Rate There is no standard addition rate for Daravair-1000. The amount to be used will depend upon the amount of air required For ob conditions, usually in the range olc 4 to 8%. Typical factors which might influence the amount of air-entraining admixture required are, temperature, cement, sand radation, and lhe use of extra fine materiL~s such as fly ash and microsilica. Typical Daravair-1000 addition rates range from 3/4 to 3 fluid ounces per 100 Ibs. (50 to 200 mL/100 kg) of cement. The air-entraining capacity of Daravair-1000 is usually increased when other concrete admixtures are contained in the concrete, particularly water-reducing admixtures and water-reducing retardors. This may allow up to a two-thirds reduction in the amount of Daravair-1000 required. Mix Adjustment Entrained air will increase the volume of the concrete making it necessary to adjust the mix pro rtions to maintain the cement Factor and yie dJ~. This may be accomplished by a reduction in water requirement and aggregate content. Dispensing Equipment A complete line of accurate automatic dis- pensing equi ment is available. These dis- pensers can ~ located to discharge into the water line, the mixer, or on the sand. Packaging Daravair-1 OOO is available in bulk, delivered by metered tank trucks and in 55 gallon (210 L) drums. Daravair-1000 contains no flammable ingredients. DARAVAIR-1000 WILL FREEZE AT ABOUT 30°F (-1 °C) BUT ITS AIR-ENTRAINING PROPERTIES ARE COMPLETELY RESTORED BY THAWING AND THOROUGH MECHANICAL AGITATION.

I · l .... I WRDA® wit Hycol Water-Reducing Admixture ASTM C 494 Type A DESCRIPTION: WRDA® with HYCOLT~4 admixture is an aqueous solution of complex organic compounds, one of which is HYCOL, a patented portland cement hydration control agent. WRDA with HYCOL is a ready to use low viscosity liquid which is factory promixed in exact proportions to minimize handling, eliminate mistakes and guesswork. WROA with HYCOL contains no calcium chloride. 1 gal. weighs approximately 9.6 Ibs. (1 I= 1.15 kg). USES: WRDA with HYCOL produces a concrete with lower water content (typically 8 to 10% reduction), greater plasticity and higher strength. It is used in ready mix plants, block and concrete products plants, in lightweight and pre- stressed work.. . wherever concrete is produced. tt is also used by contractors in field equipment such as job site plants and pavers. ADVANTAGES: Most calcium-chloride-free water-reducing admixtures on the market today produce some significant degree of set retardation. Minimal extension of set"ring time has been experienced in field concrete containing WRDA with HYCOL Under closely controlled laboratory conditions, the retardation observed with the addition of 3 fl. oz. of WRDA with HYCOL per 100 Ibs. (190 ml/100 kg) of cement is in the range of 15 to 20 minutes, well within the limit of the accuracy of the method of test. It is through the action of the patented HYdration COntroL (HYCOL) agent in the admixture that its effect on the setting time of concrete is reduced to an insignificant degree. The use of WRDA with HYCOL produces a plastic concrete that is more workable, easier to place, more pumpable, and has better finishability than plain or other admixtured concrete. In the hardened state, WRDA with HYCOL concrete has higher compressive and fiexural strengths at all ages than untreated or conventionally admixtured concrete. The greater degree of plasticity achieved, compared with conventional water-reducing admixtures, allows improved finishability. HYDRATION CONTROL: HYCOL acts to optimize the rate and degree of hydration Of the portland cement in the concrete. This optimization gives concrete strength advantages at all ages without appreciably altering its setting time. WRDA with HYCOL also acts as a dispersing agent and lessens the natural interparticle attraction between cement grains in water. This reduces their tendency to clump together, making the mix more workable, placeable and finishable with less water. The combination of water reduction and controlled hydration by HYCOL optimizes the rate of formation of the gel, the paste or binder that "glues" the concrete aggregates together. This controlled rate of gel formation adds to the water retention and internal cohesivehess of the mix, reducing the bleeding and segregation while increasing or improving the workability, placeablity and finishability of concrete. FINISHABILITY: Finishers have stated that the cement paste, or mortar, in WRDA with HYCOL admixtured concrete has improved trowelability. The influence of WRDA with HYCOL on the finishability of lean mixes has been particularly noticeable, Floating and troweling, by machine or hand, easily imparts a smooth, close tolerance surface with less machine time and labor. ADDITION RATE: Excellent results are obtained using addition rates of 3 to 6 ft. oz. of WRDA with HYCOL per 100 Ibs. (190 - 375 mill[X] kg) of cement. In some cases it may be necessary to slightly modify the addition rate due to variations In cement, aggregate or other job conditions. DISPENSING EQUIPMENT: A complete line of accurate dispensing equipment is available. WRDA with HYCOL may be introduced to the mix on the sand or in the water. COMPATIBILITY WITH OTHER ADMIXTURES: WRDA with HYCOL is compatible in concrete with all air- entraining admixtures such as DAREX II AEA®. Due to a synergistic effect of WRDA with HYCOL, the quantity of DAREX II AEA admixured in concrete may be reduced by about 25%. By combining the separate effects of air entrain- ment and dispersion, the water requirement of concrete may be reduced up to 15%. EACH ADMIXTURE SHOULD BE ADDED SEPARATELY. While WRDA with HYCOL contains no calcium chloride, it is compatible with calcium chloride in concrete mixes. Again, each should be added separately. PACKAGING: WRDA with HYCOL is available in bulk, delivered by metered tank trucks, and 55 gal. (210 I) drums. WRDA with HYCOL contains no flammable ingredients. IT WILL FREEZE AT ABOUT 28°F (-2°C), BUT WILL RETURN TO FULL STRENGTH AFTER THAWING AND THOROUGH AGITATION.

DARATARD i7 I ~.~,: Initial Set Retarder ' · ASTM C494 Type B & Type D DESCRIPTION: DARATARD®-17 admixture is a ready-to-use aqueous solution of hydroxylated organic compounds. Ingredients are factory premixed in exact proportions to minimize handling, eliminate mistakes and guesswork. One gallon weighs approximately 10.2 Ibs. USES: DARATARD- 17 retards the initial and final set of concrete. At the usual addition rate of 3 ft. oz./lO0 Ibs. cement it will extend the initial setting time of portland cement concrete by 2 to 3 hours at 70°F. DARATARD-17 is used wherever a delay in setting time will insure sufficient delivery, place- ment, vibration or compaction time, such as in: · Hot Weather Concrating · Transit Mix Concrete · Prestressed Concrete DARATARD-17 is also used in special applications, as in bridge decks where it extends plastic characteristics of the concrete until progressive defkflection resulting from in- creasing loads is completed. WATER REDUCING PROPERTIES: Along with set retardation, DARATARD-17 provides water reduction (typically 8 to 10%) in a concrete mix. This water reducing action of DARATARD- 17 produces greater plastic- ity and workability in the fresh concrete and the strength and permeability of the hardened concrete are measur- ably improved. DARATARD-17 is designed for use on jobs where high temperatures or extended setting times are the prime factors. It is recommended only when the primary purpose is to delay and control the setting time of concrete. When time and temperature are not major considerations, Grace Construction Product's water reducing admixtures such as WRDA® with HYCOLTM should be used. COMPATIBILITY WITH OTHER ADMIXTURES: DARATARD-17 is compatible in concrete with all commer- cial air antraining admixtures, such as DARAVAIR®. Due to the slight air antraining properties of DARATARD-17, itself, the addition rate of DARAVAIR may be reduced by about 25%. By combining the separate effects of air entrainment and dispersion, the water requirement of concrete may be reduced up to 15%. EACH ADMIXTURE SHOULD BE ADDED SEPARATELY. ADDITION RATES: Addition rates for DARATARD-17 will range from 2 to 5 fluid ounces per 100 Ibs. of cement. The amount to be used will depend upon the degree of retardation required under job conditions. Longer setting times or higher temperatures will require higher addition rates. Conversely, the addition rate will be lower for shorter extensions of time. DISPENSING EQUIPMENT: A complete line of accurate, automatic dispensing equipment is available. DARATARD-17 may be introduced to the mix with the sand or with the water. PACKAGING: DARATARD-17 is available in bulk, delivered by metered tank trucks, and 55-gallon drums. It contains no fiammable ingredients. DARATARD-17 WILL FREEZE AT ABOUT 28°F, BUT WILL RETURN TO FULL STRENGTH AFTER THAWING AND THOROUGH AGITATION. ARCHITECTS' SPECIFICATION FOR CONCRETE RETARDING ADMIXTURE: Concrete shall be designed in accordance with ACI Standard Recommended Practice for Selecting Propor- tions for Concrete (ACI 211.1-8i). The set retarding/water reducing admixture shall comply with ASTM Designation C 494, Type D admixture, and shall be DARATARD- 17, as manufactured by Grace Construction Products, or equal. Certification of compliance shall be made available on request. It shall be used in strict accor- dance with the manufacturer's recommendations. The addition rate shall be adjusted to produce the specified retardation of the concrete mix at all temperatures. Copyright 1993. W.R. Grace & Co.-Conn.

S~,-~h e e t ,,-,, Daracem lO0 SUPERPLASTICIZER ASTM C 494 TYPE F & TYPE G scrlption: Daracem®-I O0 is an aqueous solution of chemical dis rsonts combined wiih other chemicals w~ich increase its beneficial effects on the qualily and plasticity of a concrete mix. Daracem-1 O0 is the first high range water reducer specially formulated br extended slump life. Conventional superplasucizers normally provide only 25 to 45 minutes of slump increase before the concrete begins to lose workability. Daracem-100, however, extends the time span of the slump increase up to twice as long or longer. Chemical Action: Daracerml O0 neutralizes the surface charges on cement particles causing extreme disper- sion, resulting in complete, efficient cement hydration which, in turn, greatly increases strength development. Uses: Daracem-t 00 provides improved slump retention in flowable concrete. It is ideal for tow water/cement ratio concrete desi ned for high ea compressive and flexur~ strengths w~ exceptional workability and flow characteristics. Because of its unique ability to draw maximum effect from the cement content of a mix, it frequently gives performance with a 'F pe I cement corn rable to that otYap Type III cement. It can ~ used in precast/prestress work to reduce the high energy requirement of exter- nal heat for accelerated curing. Daracem- 100 helps to solve difficult placeabili problems such as dense rebar netvvo~ or constricted forms and job conditions requiring that the concrete be transported or pumped for long distances. A Daracem-100 mix flows easily into forms and around reinforcing steel. Even at high slump, the concrete consolidates well without segregation. Daracem- 1 O0 concrete reaches stripping stren ths quickly and finishes easily without the sti~iness, tearing and surface drying characteristics sometimes experienced with other high range water reducers. Addition Rate: Daracern-1 O0 can be added at variable addition rates to suit job requirements. The normal dosage range is 5-20 oz per 100 Ibs (325-1300 mL/100 kg) of cement. In the lower range, Daracem-100 meets the requirements for an ASTM C 494 Type F water-reducing, high range admixture and at the upper range for a Type G water-reduc- ing, high range and retarding admixture. Varying addition rates may give added slump variances to match placement needs. Should job conditions require more than rec- ommended addition rates, please consult your Grace representative. Compatibilily: Daracem-1 O0 treated concrete should use a Wood Resin air-entraining agent, (such as Daravair* and Daravair-1000) or a tall oil derivative air entrainer (such as Darex® II AEA) for proper air void parameters to provide resistance against freezethaw attack. Because of the high dispersion of Daracem-100, the use of 'F pe A & D admix- tures (water reducers/retarYYeFrs)are usually not necessary. Prei~sting of the concrete should be performed to optimize dosage rates, determine mix design and selting characteristics. Admixtures should not contact each other before entering the concrete. Pretesting to determine optimum addition rates will benefit performance. Packaging: Daracem-1 O0 is available in bulk, delivered by metered tank trucks, and in 55 gallon (210 L) drums. Daracem-100 contains no fiammable ingredients. It will begin to freeze at 32 F (0 C) but will · reconstitute to full strength after thawing and agitation. In storage and for troublefree dis- pensing, Daracem-100 should be main- rained at temperatures above 40 F (4 C). W.R.
