以立方体试块强度代表结构混凝土的实际强度,作为结构工程质量检验验收标准,在许多情况下,由于方法本身的局限性和其它因素的影响,不能满足全面质量管理的要求。目前,我国高层建筑混凝土结构发展很快,对结构工程的质量要求不断提高,对建筑工程质量的检验与控制技术的要求也更加迫切。在许多情况下,要求在结构混凝土上直接对其强度的质量状况进行测试与评定。钻取芯样法(取芯法)试验,是采用一种人造金刚石钻机,在结构混凝土指定的部位或随机确定的部位上,钻取圆柱体混凝土实样,试压芯样试件的混凝土强度,以确定
The strength of cube test blocks represents the actual strength of structural concrete as a quality inspection and acceptance standard for structural engineering. In many cases, due to the limitations of the method itself and other factors, it cannot meet the requirements of total quality management. At present, the high-rise building concrete structure in China is developing rapidly, and the quality requirements for structural engineering are continuously increasing. The requirements for the inspection and control of construction project quality are also more urgent. In many cases, it is required to test and evaluate the quality of its strength directly on the structural concrete. Drilling core sample method (coring method) test is to use a synthetic diamond drilling machine to drill cylindrical concrete samples at specified locations or randomly determined parts of structural concrete to test the concrete strength of core samples. ,To determine
