Abstract
Alkali activity test and alkali-aggregate reaction inhibition test were carried out for coarse and fine aggre-gates at different depths in the material yard.The results of tests show that the six groups of aggregates were prelimi-narily determined by petrographic method to contain alkali active mineral components.Alkali activity of aggregates was further determined by mortar rod rapid method.The six groups of aggregates all have active factors with poten-tial harmful reactions.Addition of 20%fly ash into LP5ZK1 and LP5ZK4,and addition of 15%fly ash into LC4-TK2,LP7ZK4,LP7ZK2 and LP7ZK3 can effectively inhibit the occurrence of alkali-aggregate reaction,and ensure the durability and safety of the project.关键词
