Abstract

In this study, samples of regular, high performance, expansive and the polymer concrete and mortar were prepared for test of permeability and mechanical property. In the permeability measurement, water and an aqueous chemical solution were employed as the permeant.

The test results of the samples, ranging from 5.7 x 10-9 cm/sec to 1.0 x cm/sec for the permeability and 3800 psi to 10600 psi for compression strength, indicated that the polymer coated concrete has the lowest permeability among the concretes and high performance concrete has the highest compression strength . The finding leads to the possibility that a high strength and low permeability concrete material, as required by the environmental container structure, could be achieved through the surface treatment of the high performance concrete with non-permeable polymer. This study also reveals the effects of the size exclusion and the removal of the chemical species up to 97% by the specimen in the case of chemical species used as permeants.
