各国从不同的角度研究碾压砼,日本基于施工方法的变革对砼的工作度和配合比参数进行了调整;美国上静水坝着眼坝身防渗和降低水化热温升,在砼中掺入了大量的粉煤灰;柳溪坝和以后相继兴建的一系列工程为了取得最大的技术经济效益,用水泥固结砂石料和水泥土的理论研究碾压砼。我国从 All countries studied roller compacted concrete from different angles, and the Japanese based on the change of construction methods adjusted the work intensity and mixture ratio parameters of the concrete. The United States Upper Jingjing Dam looked at the dam body seepage prevention and lowered the temperature rise of hydration heat. In the concrete, A large number of fly ash; Liu Xi dam and later to build a series of projects in order to achieve the greatest technical and economic benefits, using cement consolidation sand and cement soil theoretical research roller compacted concrete. My country from
