Sika Lebanon - Alkali-Silica-Reaction Resistant …

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 of concrete volume, causing cracking and spalling when the generated forces exceed the tensile strength of the concrete.
