How Does Microsilica Work?

Microsilica is an extremely fine powder, many times smaller than a grain of cement. When it is added to concrete, those tiny particles slip into the gaps between cement grains and make the mix much more compact.

It also reacts chemically. Cement releases calcium hydroxide as it hardens, and microsilica reacts with it to form extra binding gel. This extra gel fills pores and bonds the mix together, which is called the pozzolanic effect.

The result is stronger, denser concrete that lets in less water and chemicals. That is why microsilica is popular for bridges, marine structures, industrial floors, shotcrete and repair mortars.
