Abstract: Accelerated mortar bar test and concrete prism method were used to detect the alkali reactivity of aggregates used in Beijing. Preventive measures for the alkali-aggregate reaction of these aggregates were also presented. A new rapid test method was proposed to evaluate the effectiveness of mineral admixtures on suppressing alkali-silica reaction. Based on this method and other experiments, the mechanism of natural zeolite in preventing alkali-silica reaction was studied and the role of alkalis in zeolite was fully investigated. Finally two ways were introduced to use zeolite more effectively.
