摘　　要：为了提高活性粉末混凝土(RPC)的密实度,用最紧密堆积理论对RPC进行配合比设计.基于最紧密堆积理论,运用Matlab与Excel Solver Tool进行编程,实现RPC复合体系的静态密实堆积的理论计算,并变换配合比参数,对理论计算配合比进行验证.试验结果表明:按照理论计算配合比所配制的RPC抗压强度高达186.6MPa,抗折强度25.6MPa,且工作性能良好,相对于其他配合比,理论计算出的RPC配合比的工作性与力学性能综合为最优.可将基于Dinger-funk方程的最紧密堆积模型科学地应用于RPC配合比设计.In order to improve the compactness of reactive powder concrete（RPC）,the mix proportion of the RPC is designed.Based on the maximum density theoretical model,the theoretical computation of static dense packing of the RPC compound system is realized by using Matlab and Excel Solver Tool.The mix proportion is verified by transforming the mix parameters.Experimental results show that the RPC prepared with the designed mix proportion has very good workability and its compressive strength and flexural strength are 186.6 MPa and 25.6 MPa,respectively.The workability and mechanical properties of the designed mix proportion are optimal compared with other mix proportions.The maximum density theoretical model based on the Dinger-Funk equation can be scientifically applied to the mix proportion design of reactive powder concrete.
