摘要
采用常规的实验方法对高粉煤灰掺量碾压混凝土的强度、变形性能以及耐久性进行了研究.结果表明,保持混凝土水泥用量和用水量基本相同的情况下,增大粉煤灰掺量,碾压混凝土的力学性能、变形性能和耐久性均得到了显著的改善.保持碾压混凝土的VC值、粉煤灰掺量相同的情况下,增大粗骨料最大粒径,亦可以改善混凝土的性能.
The paper has studied the properties of roller compacted concrete(RCC) with high contents of fly ash. The results show that. keeping the same contents of cement and water, increasing the contents of fly ash in RCC could improve obviously the properties including strength, deformation, and durability. Keeping the same VC and contents of fly ash, increasing the max particle size of coarse aggregate also could improve the properties of RCC.
