Silica fume loading

Silica fume for pedestrian tunnel UHPC This is a microsilica that is widely used in ultra-high performance concrete used in the construction of pedestrian tunnels. Silica ash for bridge UHPC also improves the workability of UHPC. Due to its high fineness and filling properties, silica fume can improve the flow and pumpability of concrete, making it easier to work and pour. At the same time, the addition of silica powder can also regulate the setting time and hardening rate of the concrete and improve the early strength and late strength development of the concrete. Microsilica can also adsorb and stabilise chloride ions in concrete. Chloride ions are one of the main causes of corrosion of concrete reinforcement, and the addition of silica fume can reduce the diffusion rate of chloride ions in concrete and reduce the corrosion of chloride ions on reinforcement. This inhibition of chloride ion penetration can improve the durability and corrosion resistance of concrete.

This silica powder has multiple advantages in building applications, including enhanced strength, improved durability, better processability, reduced thermal conductivity, environmental characteristics, and cost-effectiveness Widely used in insulation materials, large-scale concrete engineering, mortar, pipe piles, and various other applications in the entire construction industry.
