| Research Abstract |
This study deals with the performance of concrete and reinforced concrete using limestone with rich powder. The mix proportion, properties in fresh and after hardened , durability such as freeze-thaw resistance, drying shrinkage and fatigue characteristic for concrete were investigated. In addition, the structural performance such as strength, deformation and crack, and fatigue characteristics for reinforced concrete were investigated. Test results show that if the amount of limestone powder is in within three times the value stipulated Japan industrial standards, the increase in the amount of powder doesn’t influence a decrease in properties of concrete harmfully, and bring the good influences, especially improvement of workability and durability.
