The most common admixtures are retarders and accelerators. In normal use, admixture dosages are less than 5% by mass of cement and are added to the concrete at the time of batching/mixing. [52] (See § Production below.) The common types of admixtures [53] are as follows: Accelerators speed up the hydration (hardening) of the concrete.
A cement accelerator is an admixture for the use in concrete, mortar, rendering or screeds. The addition of an accelerator speeds the setting time and thus cure time starts earlier. [ 1 ] This allows concrete to be placed in winter with reduced risk of frost damage. [ 2 ]
It significantly reduces water content while enhancing concrete's workability, strength, and durability. Known for its cutting-edge technology, exceptional application prospects, and superior overall performance, PCE has revolutionized concrete admixtures.
Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).
