chemical reaction of limestone and sand

Alkali–silica reaction Wikipedia

The alkali–silica reaction (ASR), more commonly known as "concrete cancer", is a swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive non-crystalline silica found in many common aggregates, given sufficient moisture.. This reaction causes the expansion of the altered aggregate by the formation of a soluble and viscous gel of sodiumget price
