| 摘 要： | 进行混凝土致密配合比设计，应首先对矿质混合料体系(集料与掺合料)进行致密配比，并采用数学手段对实验数据进行曲线拟合，正填、逆填两种顺序不同的致密配比模式在达到最低空隙率、获得基本相近的最大单位重时，粗、细集料所用质量比几乎相同，掺合料用量与填加顺序有关，为完成更为经济合理的混凝土致密配合比设计提供依据。

| Abstract: | Densified mixture ratio design of concrete, mineral admixture system including aggregates and additions should be first mixed with dense proportion. The results about two dense proportion patterns different in order are achieved by mathematical curve fitting to experimental data and formula calculation to provide basis for more economical and reasonable densified mixture ratio design of concrete. In positive-fill and counter-fill patterns, the mass ratios between coarse aggregate and fine aggregate are almost the same, while the masses of additions are obviously different because of the filling order when reaching the lowest void fraction and gaining basically near maximum unit weight. |
