| الوصف: | This paper deals with the effect of rock as aggregates containing montmorillonite on the volume change, compressive strength and Young's modulus of the concrete. Ten types of coarse aggregates were used in this study, which were andesite, basalt, sandstone and slate rock. The contents of montmorillonite in aggregates were determined with a microscope and by X-ray analysis. The concrete specimens were cured in (1) standard manner (2) wet and dry condition cycles (3) high temperature at 60°C, 110°C and 200°C and (4) freezing and thawing cycles.The summary and conclusion are follows(1) The higher the content of montmorillonite in aggregates of sedimentary rocks, the higher volume change of the concrete specimens was observed.(2) When the content of montmorillonite in sandstone aggregates exceeds 5%, the aggregates influence on the properties of concrete. |
