摘要
介绍了增粘剂的种类和作用机理,分析了增粘剂提高混凝土抗分散、抗泌水和抗侵蚀作用的特点,并介绍了增粘剂对混凝土凝结时间、抗压强度和抗拉强度的影响规律。
The types and reaction mechanism of commonly used viscosity-modifying admixtures are introduced. And the influence of various types of viscosity-modifying admixture on resistance to concrete＇s segregation and bleeding are discussed. Besides, the laws of influeuce on setting time, compressive strength, tensile strength and on resistance to corrosion are also introduced.
