Effect of casting and curing water temperature on concrete properties Год выпуска: 2014Автор: Sivakumar Naganathan,Lu Han Lin and Kamal Nasharuddin MustaphaИздательство: LAP Lambert Academic PublishingСтраниц: 88ISBN: 9783659613371Описание This book presents the investigation done on the effect of water temperatures on concrete properties. Water is an essential ingredient in concrete. The temperature of water changes according to the weather. This creates special challenges in the concrete production especially at hot climatic. Hence, there are more obstacles to overcome when using hot water to produce concrete. The effect of water temperature during casting and curing of concrete on concrete properties have been studied. Concrete samples were prepared and cured under different water temperature and the properties of concrete tested. The tests include slump, compressive strength, rebound hammer, UPV, and water absorption. From the analysis of test results, it was found that higher water temperature used during concrete mixing reduced the overall strength and other properties of concrete. Addition of hot water while mixing leads to further the defects and failure in the hardened state at 28 days, but high early strength....
