typically cement and lime as the binder, with sand or pulverized fuel ash (PFA) as the source of silica. The air cells are formed by the addition of aluminium powder, which generates hydrogen bubbles in the alkaline environment of the mix. AAC does not contain the normal cement hydration products present in concrete cured at normal temperatures.
The quicklime is then mixed with small amounts of water to create hydrated lime, which may be included in cement or mixed with water for use as mortar. Lime hardens by slowly absorbing carbon dioxide and turning back to limestone over time. Cement consists of highly reactive silica-containing compounds -- when mixed with water, they harden quickly.
Bone cement comes in two parts: 1. Powder, or the polymer 2. Liquid, or the monomer Once the powder and the liquid are mixed together, polymerization occurs and an exothermic reaction creates the final, hardened bone cement. The powder component typically consists of the following three materials:
