Abstract

This study is aimed at comparing the effect of cement mortar made of sulfuric acid treated ISO standard sand with that of cement mortar made of normal ISO standard sand. In the water absorption test, water absorption of standard sand increases with the increase of immersion time in sulfuric acid solution. The results show that at the water cement ratio of 0.5, the longer the standard sand is immersed in sulfuric acid, the greater the compressive strength of the cement mortar sample.
