Silica or silicon dioxide is found in nature in the form of quartz or sand. Control of silica structure at nano-scale level was carried out to generate silica nanoparticles. Higher compressive strength and Increased durability - longer service life.
Applications
- Better rheology - Control segregation & bleed
- Early strength development
- Increased long-term tensile-to-compressive strength ratio
- Overall increases in the early-stage compressive strength
- Reduction in thickening time of cement
- It acts physically to optimise particle packing of the concrete or mortar mixture and chemically as a highly reactive pozzolan.
