Performance of Nevada's aggregates in alkali

The reaction which occurs between reactive silica or silicates present in some aggregates and alkalis of Portland cement produces an alkali-silica gel that expands in the presence of moisture resulting in concrete cracks ACR is also a chemical reaction between reactive carbonate rocks and the alkalis present within the cement paste Get price
