| 摘 要： | 在确定了胶凝材料各组分间的最佳比例和各级别砂的最佳比例后,采用正交试验,研究了不同砂胶比、水胶比、钢纤维掺量对RPC流动度、强度以及氯离子扩散系数的影响.结果表明,随砂胶比的增大,RPC的流动度减小,抗折、抗压强度减小,氯离子扩散系数减小.随水胶比的增大,RPC的流动度增大,抗折强度增大,氯离子扩散系数增大,但抗压强度...

| Abstract: | After the best proportion of the binder ingredients and the optimal proportion of different class sands were determined,the effect of sand-binder ratio,water-binder ratio,and the volume percentage of steel fiber on the mobility,strength,permeability resistance of RPC was investigated.The results show that with the increase of the sand-binder ratio,the mobility,strength and permeability resistance of RPC decrease;with the increase of water-binder ratio,the mobility,flexural strength and permeability resistan... |
