高温养护后不同轻骨料混凝土的性能研究

Properties of different lightweight aggregate concrete after high temperature curing

针对高温养护后轻骨料混凝土的性能,国内研究相对较少。本文以LC30轻骨料混凝土为例,针对高温养护后轻骨料混凝土一般力学性能进行试验研究,分析养护温度和龄期对不同轻骨料混凝土特征强度、弹性模量和应力-应变曲线的影响,并与常温养护后其力学性能进行对比分析。

For the performance of lightweight aggregate concrete after high temperature curing, domestic research is relatively rare. Taking LC30 lightweight aggregate concrete as an example, the general mechanical properties of lightweight aggregate concrete after high temperature curing were studied. The effects of curing temperature and age on the characteristic strength, elastic modulus and stress-strain curve of different lightweight aggregate concrete were analyzed. And compared with the mechanical properties after curing at room temperature.
