| Abstract: | Anti-cracking performance of roller compacted concrete (RCC) is one of the subjects which is interested by the designers. According to the available data, the factors,i.e. tensile strength, deformation properties, thermal properties and so on, which affects crack resistance of RCC, are analyzed. Then anti-cracking performance of RCC researched. It is concluded that RCC possess good anti-cracking performance. An anti-cracking performance index of RCC is put forth. It showed that anti-cracking performance is change with the age of RCC. |
