摘要

It has become an important subject to use slag powder, basalt fiber and other admixtures and superplasticizer to dispose high durability concrete in hydraulic environment. Because basalt fiber can improve the shrinkage and crack resistance of concrete, this test uses slag powder and superplasticizer to configure concrete. On the basis of satisfying strength, basalt fiber is added to carry out comparative tests. It is concluded that the durability and strength of basalt fiber concrete with slag powder of about 700 m2/kg are better than that of ordinary concrete and slag powder with specific surface area of about 700 m2/kg and 1.5 kg/m3 basalt. Rock fiber has the best cost and performance effect on concrete. Its water‐binder ratio is low, strength is high and durability is good. It can realize the universal application of high performance concrete.
