Silica fume for class I roads commercial concrete it is an additive added to commercial concrete used in the construction of primary roads.Our silica ash for commercial concerete are available in different purity and content.Improve the strength and durability of concrete. Microsilica contains large amounts of silica (SiO2) and calcium oxides (CaO), which react with calcium hydroxide (Ca(OH)2) in the cement to form a stable hydrated calcium silicate gel, thereby increasing the compressive, flexural and tensile strength of concrete. Improvement of working properties of concrete. The fine particles of silica fume can fill the voids in the concrete, reduce the porosity and increase the densification of the concrete, thus improving its plasticity and ductility and reducing shrinkage and cracking. This silica powder has multiple advantages in building applications, including enhanced strength, improved durability, better processability, reduced thermal conductivity, environmen…
