混凝土的骨料级配,关系到混凝土的密实程度和经济价值,尤其在巨型混凝土水工建筑物中,骨料的级配更密切关系到水泥水化热所造成的裂缝,营造价格和施工问题。近年来混凝土骨料级配在国内取得了不少成就,首先是佛子岭水库工程创造了对三级配的资料统计分析方法。早在1901年W·B富勒(Fuller)统计了大量混凝土级配资料得出著名的抛物线形级配曲线和椭圆与直线的复合曲线;30年后,C·A·G韦毛氏(Weymouth)发表了颗粒级配相碍理论,韦毛氏从理论上推演的结果与富勒氏曲线极为相似。此外还有苏联的P曲线。但是韦毛氏 Aggregate grading of concrete, relates to the density and economic value of concrete, especially in the huge concrete hydraulic structures, aggregate gradation is more closely related to the cracks caused by cement hydration, to create the price and construction problems . In recent years, concrete aggregate gradation has made a lot of achievements in China. The first is that the Fulingziling Reservoir Project has created a statistical analysis method for the data of the three gradations. As early as 1901, W. Fuller calculated a large number of concrete grading data to obtain the well-known parabolic gradation curve and the compound curve of ellipse and straight line. Thirty years later, Weymouth ) Published a particle grading obstruction theory, Wei Mao’s theoretical deduction and the Fullerton curve is very similar. In addition there is the P curve of the Soviet Union. But Wei Mao’s
