干砂浆 meaning in Chinese

dry mortar

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
在此基础上建立了普遍适用的更精确的混凝土体积模型，提出了“干砂浆体积”概念，同时吸收国外关于最佳浆集比概念，用数学方法推导建立了混凝土用水量和砂率的计算公式：用水量公式：砂率公式：这两个公式结合传统的水胶比定则(保罗米公式) ，即可全面定量地确定混凝土的所有组成材料的用量，实现混凝土的全计算配合比设计。
