钢纤维活性粉末混凝土配合比试验研究

Experimental study on the proportions of raw materials of reactive powder concrete with steel fibre

通过钢纤维活性粉末混凝土(RPC)的配制试验,研究水胶比、高效减水剂、硅灰、钢纤维掺量及砂子种类对RPC抗折、抗压强度的影响规律。结果表明:钢纤维的掺入使得试件破坏时裂而不散,试件的延性性能及强度指标都得到了明显的提高。

Experiment study on the proportion of reactive powder concrete with steel fibre was conducted, the factors affecting the flexural strength and compressive strength of reactive powder concrete was studied, which include the water and binder ratio, superplasticizer, silica fume, steel fibre and different kinds of sand. The experiment results show that the specimens of reactive powder concrete with steel fibre cracked but did not fall apart, whose ductility and strength were improved significantly.
