AI Technical Summary
Nano-silica reinforcing agents tend to agglomerate in permeable concrete. The pozzolanic effect consumes calcium hydroxide, clogs pores, and leads to a decrease in permeability. Furthermore, the adsorption of free water increases the viscosity of the slurry and results in uneven permeability channels.
Using rice husk ash as raw material, an amorphous carbon coating layer is formed through oxygen-controlled calcination and acid washing. Combined with high-temperature reaction, Si-C chemical bonds are formed, which stabilizes the distribution of silica, avoids agglomeration, and maintains water permeability during cement hydration.
It improves the uniformity of nanoparticle distribution in cement paste, refines pores, maintains good permeability, and enhances the mechanical properties and permeability uniformity of concrete.
