Alkali-aggregate reaction in California concrete aggregates
Principal reactions are between cement alkali and opaline shale or intermediate to acid volcanic rocks; expansion, cracking and deterioration usually result from such reactions; reactivity of aggregate can be estimated by service history, mortar bars, chemical tests, and petrographic examination; reaction may be inhibited by limiting cement alkalies or by adding corrective pozzolan.
