If -'l ~,~ CH/EVEtJ\€.'- A DESCRIPTION Sika AEA-15 admixture is a liquid solu- tion of concentrated organic materials. It has been formulated and manufactured specifically to provide stable and p~e- dictable air contents in concrete, with uniform air bubble spacing throughout the concrete matrix. Sika AEA-15 meets the requirements of ASTM C-260 for air entraining admixtures and AASHTO M-154 APPLlCA TlONS Sika AEA-15 can be used whenever air entrained concrete is desired. Ready- mix, precast and block producers can all achieve optimum entrained air con- tents, even where harsh mixes are used or fly-ash is added to the mix. ADVANTAGES Air entrainment is recognized as the most effective prevention against con- crete scaling in exposed environments. Air entrained concrete delivers particu- lar benefits in the form of increased concrete durability. This is important in colder climates where frost and freeze- thaw cycles can cause scaling and dam- age to the concrete surface. Air entraining agents help to prevent scaling by creating millions of micro- scopic air voids, allowing water trapped in the concrete to expand when the concrete freezes, thus preventing cracks caused by natural expansion. Entrained air voids in the concrete will also increase durability In harsh environments where concrete is exposed to deicing salts, marine salts and sulfates. Workability and placeability are also im- proved by the lubricating action of the microscopic bubbles in the concrete. Concrete will flow better, and bleeding and shrinkage will be reduced because less water is needed to obtain the desired workability. Sika @ AEA-15 Air Entraining Admixture . HOW TO USE DOSAGE Addition rates will vary depending on the air content required for a particular project. Typically air contents will be specified in the range of 4 to 8 percent by volume. Other factors that may affect the amount of air entrained into the concrete include, but are notlimited to, cement content and type, sand gradation, temperature and water content. Sika recommends that trial mixes be tested whenever material or any other changes are made that may affect the amount of entrained air. Dosage rates for Sika AEA-15 will typi- cally fall between 1/4 and 1 fl. oz. 1100 Ibs. (16 - 65 ml/100 kg) of cement to entrain between 4 and 6 percent air. Higher air contents may be obtained by increasing the dosage rate. Combination with other admixtures, par- ticularly water reducers and retarders, wi.1I tend to increase the amountof entrained air in the mix. Air contents should be checked with an air-meter after batching and dosage adjustments made at the concrete plant. MIXING Measure the required quantity per batch manually or with automatic dispenser equipment. Add Sika AEA-15 to mixing water or sand. Do not mix with dry ce- ment. When used in combination with other 77/99 admixtures, care must be taken to dis- pense each admixture separately into the mix. PACKAGING Sika AEA-15 is supplied in 55 gallon (208 liter) drums and bulk delivery. STORAGEANDSHELFLWE Sika AEA-15 should be stored at above 350F (20C). If frozen, thaw and agitate thoroughly to return to its normal state before use. Shelf life when stored in dry warehouse conditions between 500F and 800F (1QoC - 270e) is 1 year minimum. - CAUTION Skin and eye irritant; avoid contact. The use of NIOSH/MSHA approved respirator, safety goggles and rubber gloves is rec- ommended. Avoid breathing product. Use with adequate ventilation. Remove con- taminated clothing. FIRST AID Wash skin with soap and water. In case of eye contact, flush with water for 1 5 minutes; contact a physician. Wash cloth- ing before re-use.

"l -,~ Cf..{/f:::VElJIf.,'- A DESCRIPTION Plastocrete 161 is a polymer-type water- reducing admixture. Plastocrete 161 contains no chlorides. Plastocrete 161 meets the requirements of ASTM C-494 Type A and AASHTO M194 Type A. APPLlCA TlONS Plastocrete 161 is recommended for use in all applications where high quality concrete with superior workability and normal setting times is required. HOW IT WORKS Plastocrete 161 water reducing admix- ture provides an economical and highly effective means of reducing the amount of mixing water required to produce con- crete of a certain slump by acting as a dispersant for the cement particles in the mix. Through this dispersing action more of the surface area of the cement particles is available for early hydration. The more cement particles hydrated by contact with the mixing water, the greater the compressive strength of the concrete. ADVANTAGES Plastocrete 161 is formulated as a Type A water reducer to allow 7 - 10% water reduction and maximize the benefits of increased hydration in both the hard- ened and plastic states. BENEFITS A Reduced water content required to achieve desired slump. increases compressive and flexural strengths and allows the use of more economi- cal mixes. A Improved paste quality makes con- crete easier to pump and finish. Plastocrete@ 161 11/99 Water Reducing Admixture (Type A) A Consistent normal setting times through- out the recommended dosage. A Lower water cement ratios provide decreased permeability and increased durability. Combination with other Admixtures: Plastocrete 161 works effectively as a single admixture or in combination with other admixtures in the Sika System. When air entrained concrete is specified. Sika recommends the use of Sika air entraining agents. HOW TO USE DOSAGE Addition rates of 3 - 6 fl. oz.l100 Ibs. (195 - 390 mlll00 kg) of cement are recom- mended for general concrete applications where normal setting characteristics are desired. MIXING Plastocrete 161 is added at the concrete plant. Measure required quantity manually or by automated dispenser. Add into the sand at the weigh hopper or into the water line at the batch plant. When used in combination with other ad- mixtures. care must be taken to dispense each admixture separately into the mix. Do not mix with dry cement. PACKAGING Plastocrete 161 is supplied in 55 gallon (208 liter) drums and bulk delivery. STORAGE AND SHELF-LIFE Plastocrete 161 should be stored at above 350F (20C). If frozen. thaw and agitate thoroughly to return to normal state before use. Shelf life when stored in dry warehouse conditions between 500F and 800F (1 OOC - 270C) is one year minimum.

Plastiment meets the requirements of ASTM C-494 Types Band 0 and AASHTO M194 Types Band O. APPLlCA TlONS Plastiment is recommended for use when- ever high quaility concrete with predict- able and controlled set times is desired. Use in flatwork and horizontal or vertical slipform placements where a superior surface finish is required. ADVANTAGES Plastiment is highly effective in hot weather concreting to offset the accel- erating effects of high ambient tempera- tures by controlling the heat of hydra- tion. Concrete workability is enhanced and a superior surface finish is obtained. BENEFITS A In mass concrete pours Plastiment controls temperature rise and reduces the risk of thermal cracking. A Initial set times are delayed, allowing time for proper placement and finish- ing without cold joints in hot weather conditions. A Plastiment increases concrete density and delivers increased early and ulti- mate, compressive and flexural strengths. Plastiment 1/97 Water Reducing and Retarding Admixture (Types B & OJ A For flatwork applications Plastiment acts as a finishing aid, workability is improved, bleeding is controlled and a superior surface finish is obtained. A Lower water cement ratios provide decreased permeability and increased durability.
