| Abstract: | In this paper,we use the local raw materials of Fujian Province to reach a mixing proportion of RPC,apply self-made rapid assessment device to test the crack resistance of cementitious composite under normal maintenance conditions relating to the effects of water-cement ratio and steel fiber content,in order to find out super high perfor-mance of cracking resistance of RPC、mechanical properties and the workability.According to cracking time or a ratio of tensile stress and bending strength of RPC,we establish rapid method of assessing the cracking performance of RPC,and provide cracking indicators and cracking indicators for the purpose of assessing cracking value. |
