STUDY ON STRENGTH AND PERMEABILITY OF CONCRETE USING LOW QUALITY COARSE AGGREGATES FROM CIRCUM-PACIFIC REGION

Abstract

This study attempts to examine the strength and durability of concrete using low quality coarse aggregates from the circum-Pacific region. The research starts with the examination of the strength and durability of low quality coarse aggregates from the circumPacific region, and subsequently examine for the influence of the low quality coarse aggregate on the concrete characteristics. Lastly, the quality improvement methods: the coating of coarse aggregate and combined with the normal aggregate methods, for concrete using the low quality coarse aggregates are proposed. As a result, it can be concluded that the strength and durability of concrete using low quality coarse aggregate can be clarified by the strength and durability of low quality coarse aggregate. In addition, the improvement methods proposed in this study can be successfully implemented for improving the strength and durability of concrete using low quality coarse aggregate.
