On this base, a more precise volume model of concrete is established and one conception of dry mortar volume is brought forward. at the same time the author absorbed the concept of the best ratio between paste and aggregates and used mathematical method to induce the formulas of water content and ratio between fine aggregate and coarse aggregate in concrete : ratio between fine aggregate and coarse aggregate : if the two formulas are connected with the classical rule of water cementitious materials ratio ( bolmy formula ), the contents of all materials in concrete can be determined completely by calculation and overall calculation proportioning is realized
在此基礎上建立了普遍適用的更精確的混凝土體積模型，提出了「干砂漿體積」概念，同時吸收國外關于最佳漿集比概念，用數學方法推導建立了混凝土用水量和砂率的計算公式：用水量公式：砂率公式：這兩個公式結合傳統的水膠比定則（保羅米公式） ，即可全面定量地確定混凝土的所有組成材料的用量，實現混凝土的全計算配合比設計。
