混凝土强度检验结果是否满足设计要求,是评定混凝土合格与否的一个重要指标。影响混凝土强度不足的因素有很多,但对其影响最大的因素有:混凝土配合比、组成混凝土的原材料质量、混凝土拌合物工作性能、混凝土施工及养护条件四个方面。1混凝土配合比配合比是混凝土的核心。由于生产、施工的实际现场与试验室的试配条件存在较大的差异,导致试配强度与实际生产和施工的强度差异较大。混凝土配合比异常的预防措施如下:(1)一般情况下,混凝土配合比设计过程中,应该提高
Whether the test results of concrete strength meet the design requirements is an important index to assess whether the concrete is qualified or not. There are many factors affecting the strength of concrete, but the most influential factors are: concrete mix, the quality of the raw materials of concrete, concrete mix performance, concrete construction and curing conditions. 1 ratio of concrete mix is the core of concrete. Due to the big difference between the actual site of production and construction and the trial conditions of the laboratory, there is a big difference between the intensity of the trial production and the intensity of actual production and construction. Prevention of concrete mix abnormalities are as follows: (1) Under normal circumstances, the concrete mix design process should be improved
