CONCRETE ADMIXTURES • Admixtures are material other than cement, aggregates & water that are added to concrete either before or during mixing to alter its properties & performance in fresh (workability, setting time etc) and hardened state (strength, durability etc.) Chemical Admixtures for Concrete, 3rd ed, by Rixom R. M., Effects of grouting, shotcreting and concrete leachates on backfill geochemistry, A literature review of mixed waste components: Sensitivities and effects upon solidification/stabilization in cement-based matrices. Retarding Admixtures. Admixtures (concrete admixtures) can be used for the following purposes:. Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. EN 934, covers admixtures for concrete (Part 2), mortar (Part 3), grout (Part 4) and sprayed concrete (Part 5). admixtures, admixtures to reduce potential for alkali aggregate reactivity, pumping aids, permeability reducing admixtures, workability retaining admixtures, rheology and viscosity modifying admixtures and a variety of colors and products that enhance the aesthetics of concrete. Chemical admixtures are added to concrete in very small amounts mainly for air entrainment, reduction of water or cement content, plasticizing of fresh concrete mixtures or to control the setting time of concrete.
