随着建筑行业的蓬勃发展,混凝土在我国工业与民用建筑中的应用愈来愈广泛。由于混凝土多用作结构材料[1],因此,混凝土的质量直接影响着建筑物的工程质量,而混凝土的质量又取决于混凝土的设计配合比。那么,运用混凝上强度公式进行混凝土配合比设计时,就涉及到如何确定混凝土强度公式中经验系数的问题。目前,我们石河子地区各个建筑施工单位所采用的混凝土配合比,大部分是沿用很早以前有关部门提供的混凝土配合比参考表来生产拌和混凝土的。由于各个建筑施工单位所采用的水泥品种各不相同。而且随着时间的推移,骨料特征亦有所变异,各个施工建筑单位仍然
With the vigorous development of the construction industry, the application of concrete in China’s industrial and civil construction has become increasingly widespread. Because concrete is used as a structural material [1], the quality of the concrete directly affects the quality of the building’s construction, and the quality of the concrete depends on the design mix of the concrete. Then, when using concrete strength formulas for concrete to design concrete mix ratios, it involves how to determine the empirical coefficient of concrete strength formula. At present, most of the concrete mix ratios used by construction units in the Shihezi area are based on concrete mix ratio reference tables provided by relevant departments long ago to produce mix concrete. Due to the different types of cement used by each construction unit. And over time, the characteristics of aggregates have also been mutated, and each construction and construction unit still has
