Alkali-silica reaction in concrete - Understanding Cement

ASR is caused by a reaction between the hydroxyl ions in the alkaline cement pore solution in the concrete and reactive forms of silica in the aggregate (eg: chert, quartzite, opal, strained quartz crystals). A gel is produced, which increases in volume by taking up water and so exerts an expansive pressure, resulting in failure of the concrete.

Cementitious Materials - National Concrete Pavement Technology Center

Cements such as ordinary portland cement (OPC) and portland-limestone cement (PLC) react with water in a nonreversible chemical reaction called hydration to form strong, stiff, and impermeable hydrated cement paste. Supplementary cementitious materials (SCMs) contribute to a concrete's fresh and hardened properties through hydraulic reactions with water and/or pozzolanic reactions with calcium hydroxide (CH) during the formation of the concrete's hydration products.

Cement Types

In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds.
