Dec 28, 2020The alkali in the concrete chemically reacts with the aggregate whose chemical composition is active silica. After the alkali-silicic acid gel is formed, it absorbs water and expands, and the expansion stress causes the concrete to crack. This process is called the alkali-aggregate reaction.
