混凝土多功能复合外加剂的制备与性能研究

Preparation and Property Study of Multifunctional Composite Concrete Admixtures

研制了一种多功能混凝土复合外加剂。实验结果表明,该外加剂不仅能增加混凝土拌合物流动性,改善保水性和粘聚性,提高其工作性能;同时还可改善水泥浆体的毛细孔结构,提高混凝土力学性能,提高抗渗透和抗硫酸盐侵蚀等综合耐久性能。

In this paper,Composite Multi-functional Concrete Addities are researched.The test results indicated that the composite addities increase certainly slump of concrete,while decrease its loss of slump, improve the mechanism and workability obviously of concrete.In addition,the composite addities can also improve the structure of the pores of cement paste to enhance their mechanical properties and anti permeability and sulfate attack performance of concretes.
