Effect of Thermal Stimulated Super-plasticizer with BFS & Cement. Combined Effect of Thermal Stimulation of Super-plasticizer with BFS on Fresh and Hardened property of mortar

      Аннотация: By studying this book, you should understand the efficiency of thermal stimulated super plasticizer on fresh and hardened property of mortar. In the modern concrete, super-plasticizer is the essential and unforgettable part in concrete industry. Due to the massive used of concrete in the climatic changes of construction site it is essential to understand effect of temperature on super-plasticizer. This is totally a new phenomenon in the concrete history, for the first time thermal evaluation of super-plasticizer has been study in this university, a few numbers of people researched in this field, all of them reported positive incase of application of super-plasticizer due to external temperature. The focus of this experimental study is on fluidity, flow loss, air-content, density, dynamic light scattering tests for evaluation of changes in the molecular weight of heated and non-heated super-plasticizer and compressive strength by crashing the sample and by ultrasonic pules velocity tests.
