BAIJIAN - Third party testing organization
Mineral admixtures refer to inorganic mineral fines added during the preparation of concrete that can improve the performance of fresh and hardened concrete. Usually、 the amount of mineral admixtures is greater than 5% of the cement dosage、 and the fineness is the same as or finer than that of cement. Mineral admixtures include fly ash、 granulated blast furnace slag、 silica fume、 limestone powder、 steel slag powder、 phosphorus slag powder、 zeolite powder、 and composite mineral admixtures
1. Improving the mechanical properties of hardened concrete
Concrete with mineral admixtures has a dense structure and excellent interfacial bonding performance、 exhibiting good physical and mechanical properties.
. On the premise of improving the performance of concrete、 mineral admixtures can replace cement by 30% -50% in equal amounts to prepare concrete、 greatly reducing the amount of cement used2. Improving the workability of mixed concrete
Mineral admixtures are made through ultrafine grinding technology. In freshly mixed cement slurry、 they can increase the fluidity of the cement slurry and effectively control the slump loss of concrete.
. The specific surface area of mineral admixtures is 350-1500m3/kg. Due to the adsorption of water by large specific surface area particles、 it plays a role in water retention、 weakens water permeability、 and significantly improves adhesion3. Improving the Durability of Concrete
