摘要
通过对183块商品混凝土立方体试块在5个早龄期(3d、7d、14d、28d、60d)的抗压试验,拟合出了标准养护条件下不同龄期商品混凝土立方体强度计算公式,该公式的计算结果与实测结果吻合较好.可以应用到早龄期商品混凝土强度的推算.
As aresult of compressive tests on 183 cubic specimens at 5 ages,a formula for computing the cubic compressive strength of concrete at different ages under standard curing conditions are proposed, and a comparison of calculated results with experimental results shows good agreement. Finally, reserch achievements offered by this paper have reference for the designing and construction of premixed concrete.
