骨料类型对早龄期混凝土常温下力学性能影响研究

Influence of aggregate types on mechanical behavior of early age concrete at room temperature

对钙质、硅质骨料混凝土立方体和棱柱体常温下的力学性能进行试验研究。试验结果表明,早龄期混凝土力学性能主要取决于试件养护龄期,骨料类型对其影响较小。相对而言,骨料类型对早龄期混凝土抗压强度和弹性模量影响较小,对早龄期混凝土劈裂抗拉强度影响较大。

This paper has investigated mechanical properties of concrete in the early age which contains different kinds of aggregates at room temperature.The results show that early-age mechanical properties of concrete depends on the specimen curing period.Aggregate type has less affected on concrete early-age performance.In contrast,aggregate type has little effect on compressive strength and modulus of elasticity of early-age concrete,but it has greater impact on splitting tensile strength of early age concrete.
