摘要
为探究再生混凝土空心砌块抗压强度及抗剪强度与养护龄期之间关联性,文中对不同养护龄期下混凝土空心砌块砌体的力学性能差异展开试验.试验结果表明,养护龄期延长的过程中再生混凝土空心砌块的抗剪强度、抗压强度均得到显著提升;抗压、抗剪强度均在养护龄期从7d延长至14d期间提升幅度最明显;建议工程实践根据实际需求,提升高砌体强度形成效果.
Abstract
In order to explore the relationship between compressive strength,shear strength and curing age of recycled concrete hollow block,the paper conducted experiments on the differences in mechanical properties of concrete hollow block under different curing ages.The test re-sults show that the shear strength and compressive strength of recycled concrete hollow blocks are significantly improved with increasing curing age.The compressive strength and shear strength increased most obviously when the curing age was extended from 7 days to 14 days.It is sug-gested to improve the forming effect of high masonry strength according to the actual demand in engineering practice.
