It has been formulated and manufactured specifically to provide stable and pre- dictable air contents in concrete. with unitorm 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 APPLICATIONS Sika All can be used whenever air entrained concrete is desired. Heady - mix, precast and block producers can all achleve 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 naturalexpans€on. Entrained air voids in the concrete will also increase durability in harsh environments where concrete is exposed to deic in9 salts, marine salts and sulfates. Workability and placeability are also €m- 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. Air Entraining Admixture LOW TC DOSAGE Addition rates will vary depending on the air content required for a particular project. Typically air contents will be specified Inthe range of 4 to 8 percent by volume. Other factors that may affect the amount of air entrained intothe concrete include, butare not limitedto, c:ementcoMentand type, sand gradation, temperature and water content. Sika recommendsthattrial mixes betested 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 114and 1 fl.oz. /100ibs. (16 - 65 ml /i00 kg) of cement to entrain between 4 and 6 percent air. Hlgher alr contents may be obtained by Increasing the dosage rate Combination with other admixtures, par - ticutarly water reducers and retarders, will tend to increase the amount of entrained air inthemlx. Air contents should be checked with an air-meter after batching and dosage adjustments made at the concrete plant. M/XINO 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 admixtures, care must be taken to dis- pense each admixture separately into the mix.
