摘要:
系统研究了0％、30％、50％、70％和100％5种粗骨料取代率对再生混凝土立方体抗压强度、棱柱体抗压强度、劈裂抗拉强度、抗折强度以及弹性模量等力学性能的影响.试验结果表明,随着再生粗骨料取代率的增加,再生混凝土立方体抗压强度和棱柱体抗压强度均逐渐增大,劈裂抗拉强度有一定程度的降低,弹性模量逐渐降低.结合试验数据分析,建立了再生混凝土立方体抗压强度与棱柱体抗压强度、劈裂抗拉强度、抗折强度以及弹性模量的换算关系.
Abstract:
The mechanical properties of recycled aggregate concrete( RAC )were studied with the replacementrate of0%,30%,50%,70% and 100%,such as the cube compressive strength, prism compressivestrength, spliting tensile strength, flexural strength and modulus. The test results have shown that with the re.placement rate of recycled coarse aggregate , the cube and prism compressive strength are gradually increasedthe splitting tensile strength has decreased to some extent, and the modulus is gradually decreased. Combinedwith the analysis of test data, the conversion relationship between the prism compressive strength, splitlingtensile strength , flexural strength, modulus and the cube compressive strength are established.
