Abstract

PURPOSE:To decide the degree of the alkaline aggregate reactivity of an aggregate to be tested from the result of measurement by immersing the crushed samples of the aggregate into an alkaline soln. and refined water, respectively in a hermetic container and measuring a change in the liquid pressure in the container based on the expansion of both by water absorption. CONSTITUTION:The samples S in the absolute dry state formed by crushing the aggregate to be tested are immersed into the alkaline soln. A and the refined water W, respectively, in the hermetic container 1 and the change in the liquid pressure in the container 1 based on the expansion of both by the water absorption is measured 3. The degree of the alkaline aggregate reactivity of the aggregate is decided from the result of this measurement. The expansion of the aggregate having the higher alkaline aggregate reactivity in the alkaline soln. is higher in general and, therefore, the liquid pressure in the hermetic container is increased by the expansion of the aggregate samples if the aggregate samples are immersed in the alkaline soln. in the hermetic container. The degree of the alkaline aggregate reactivity is thus known by measuring the change in this liquid pressure.
