摘要
从碾压混凝土的强度、抗渗性、表面自然碳化试验和浆体水化、微观结构等方面对粉煤灰掺量的研究表明 ,粉煤灰合适掺量的确定应综合考虑各项性能及经济性 ,粉煤灰的最大掺量一般可以达到 75 %左右。
The experimentsof compressive strength,seepage prevention,surface nature carbonization and microscopic analysis of high fly ash contained RCC show that the suitable volume of fly ash used in the RCC should depend on the properties and the economic value of RCC.Generally,the highest mixture of fly ash in RCC may be up to 75 percent.
