Alkali silica reaction (ASR) is a long-term reaction between certain aggregates containing amorphous silicate phases and the alkalis from the cement paste. These silicates react with the alkalis present in the pore solution of the cement paste and form an ...
Supplementary cementitious materials (SCM) are known to reduce or even stop expansion due to alkali silica reaction (ASR) in concretes with reactive aggregates. Studies indicate that the main reason for this is the decrease in alkalinity of the pore soluti ...
One of the most serious causes of degradation of concrete is the alkalisilica reaction. Amorphous silicates present in certain aggregates react with the alkaline pore solution of the concrete to form a gel, which absorbs water and swells, leading to the ex ...
It is known that the addition of supplementary cementitious materials (SCMs) in concretes reduces or even stops expansion due to alkali silica reaction (ASR). It has been widely shown that the main mechanism controlling ASR in blends is the alkali fixation ...
