Alkali–silica reaction - Wikipedia

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

Beneficial Use of Carbon Dioxide in Precast Concrete ...

For a ,reaction, within a 24-hour process window, the theoretical maximum possible carbon uptake in ,concrete, is found to be 29% based on cement mass in the product. To reach the maximum uptake, a special process is developed to promote the ,reaction, efficiency to 60-80% in 4-hour carbon dioxide curing and improve the resistance to freeze-thaw cycling and sulfate ion attack.
