Abstract

The damages due to alkali-aggregate reaction between the reactive silicia constituents of the aggregate and the alkalies in cement have been frequently reported since 1923 in America . Recently alkali-aggregate reaction, especially alkali-silica reaction, can be found all over the area using crushed stones. The first research, in 1990, was performed to identify the alkali-silica reactivity of 18 sets of crushed stones used in domestic ready-mixed concrete plant as coarse aggregates by 4 petrollgical, chemical and mortar bar method, And the study was continued with 10 sets of crushed stones in this research. It was found that all the aggregates used in this study are innocuous at alkali-silica reaction.
