摘要:In order to study the curing ages and aging degree influences on concrete tensile strength, the splitting experiments on 25 groups specimens including 75 cubes were conducted in the paper. The test parameters mainly include strength grade, age and aging degree. The tests showed that the splitting strength increases with the age and it increases rapidly in the first 7 days. The aging degree has a certain effect on the splitting tensile strength of concrete, and the greater difference in aging degree, the greater difference in splitting strength of concrete. The splitting tensile strength predictor formulas which include curing ages and aging degree parameters were obtained by least square method based on the test results.
