Sikacrete®-950 DP may be stored in bulk storage in a cement silo and be batched in the same manner as bulk cement. The 25 lb. bags of Sikacrete®-950 DP are repulpable or shredable bags, these bags are intended to be added directly to central or truck mixer without opening. The bags are designed to disintegrate through a combination of wetting and grinding the paper during concrete mixing. Specific batching and mixing instruction procedures for Central and truck mixing as outlined in the Silica Fume Association Users Manual and ASTM C94/C94M must be followed.
Limitations: Do not introduce repulpable bags into concrete mixes with low watercementitious ratios and smaller size aggregates as these mixes may not develop sufficient mixing energy to fully repulp the bags. Always determine repulpability of bags by pretesting mix designs and batch sequence.
Please contact your local Sika representative for more information and assistance.
Compatibility with cement and other admixtures: Sikacrete®-950 DP is compatible with all known portland cements manufactured under ASTM specifications. The low water cement ratios typically specified for concrete containing microsilica make the use of a high range water reducer, such as a ViscoCrete® or Sikament® product essential in most applications. Sika® recommends the use of Sika® air entraining admixtures where air entrained concrete is required.
Workability and Finishing: Microsilica may affect the finishing characteristics of the concrete, particularly where warmer ambient conditions are encountered. The amount of bleed water from the concrete also may be reduced and Sika® recommends the use of a finishing aid and evaporation retarder such as SikaFilm® to aid finishing.
