水工碾压混凝土配合比正交设计

高掺粉煤灰、低水泥用量、中等胶凝材料、低Vc值,是目前碾压混凝土配合比设计的指导思想.单位用水量、水胶比、粉煤灰掺量和砂率是碾压混凝土配合比设计的四个主要参数.本次试验是通过正变试验的分析和计算,确定满足设计要求的水工碾压混疑土配合比参数,探讨水工碾压混凝土配合比设计的方法.

The orthogonal design for RCC in hydraulic structure

Higher content of fly ash,low cement,middle cementing material,low-value Vc,is the ideal mix ratio of RCC design.Unit water consumption,water-cement ratio,the amount of fly ash and sand rate is four main parameters of RCC design.The test has passed Orthogonal analysis and calculations,and determined the mix ratio parameters satisfied the design requirements of hydraulic structure RCC and discussed the design approach.
