摘要
在构建"集料干涉假说"的理论基础下,作者用动量守恒定理建立了集料干涉的数学模型,揭示了集料干涉的本质机理,提出了改善轻质混凝土匀质性的技术途径;并在此基础上分别研究了集料的相对体积比例、集料的颗粒级配对轻质混凝土匀质性的影响规律,最后提出了集料之间发生明显干涉的条件。
Under the theoretical foundation of ＂aggregates interference hypothesis ＂,Author established mathematical model of aggregates interference by Momentum Conservation Theorem,exposed essential mechanism,put forward technological routes to improve the homogeneity of lightweight concrete.Based on these,author also studied the laws of the relative volume proportion and grain composition of aggregates on homogeneity of lightweight concrete,finally,proposed obvious interference conditions among aggregates.
