减水剂对水泥早期水化的影响水泥水化历程,水化速度除了由水泥本身组成决定外,还受许多因素影响。如水固比(W/S),物料细度,水化温度等,而外加剂的类型和数量也是一个很重要的影响因素。有些外加剂的引入能够加速水泥水化和强度的发展,如氯化钙等,能使水化率增高主要形成短纤维状水化硅酸钙,可提高早期强度,是一种早强剂。有些外加剂可以延缓水化,如木质磺酸盐是一种缓凝剂 Effect of Water Reducing Agent on Early Hydration of Cement Cement hydration process and hydration rate are influenced by many factors besides the composition of cement itself. Such as water-solid ratio (W / S), material fineness, hydration temperature, etc., and the type and amount of additives is also a very important factor. The introduction of some additives can accelerate the development of cement hydration and strength, such as calcium chloride, can make the hydration rate increased mainly the formation of short fibrous hydrated calcium silicate, can improve the early strength, is an early strength agent. Some additives can delay the hydration, such as lignosulfonate is a retarder
