The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influence the concrete's freshly mixed and hardened properties, mixture proportions, and economy.
Alkali–silica reaction WikipediaThe 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 noncrystalline (amorphous) silica found in many common aggregates, given sufficient moisture.
