最佳级配 meaning in English
iptimum gradation
optimum gradation
Examples
- Because the best grade limits does not vary with material property , firstly , we can confine material grade to the best grade limits when doing subbase mixture design , secondly , after systematic temperature contraction test , aridity contraction test and compressive strength correction test , we can determine the best cement percentage which has the best crack resistance property
因为最佳级配范围是与粒料的粒径大小有关的，所以在基层材料配合比设计时可首先将材料级配限制在最佳级配范围以内，然后通过系统的温缩、干缩性能试验以及抗压强度校核试验，最终确定抗裂性较好的合理水泥剂量。
