WHY USE SILICA BASED PRODUCTS?
Alkali Silica Reaction is a chemical reaction which occurs between the amorphous silica in the aggregate and the pore solution (alkalis) of the cement matrix. The reaction results in an increase in concrete volume, causing cracking and spalling when the generated forces exceed the tensile strength of the concrete.
How to avoid grinding abrasion?
The surface can be considerably enhanced against grinding abrasion through the use of micro silica and/or surface hardener scattered on the surface. In order to boost resistance against percussive or striking attack, the toughness and flexural strength of the concrete must be improved.
