自保温再生混凝土的配合比优化设计
Optimization of Mix Proportion Design of Thermal Insulation & Recycled Concrete
摘要
Abstract
With the total recycled coarse aggregate replacement, the influence of recycled fine aggregate replace-ment ratio and glazed hollow bead volume replacement on thermal insulation&recycled concrete were studied by exper-imental tests.The cubic compressive strength, thermal conductivity and density of 28 d aged concrete specimen were tested, the experimental results were analyzed, and the mix proportion design of thermal insulation&recycled concrete was optimized with 28 d cubic compressive strength and thermal conductivity consideration.The results showed that:the cubic compressive strength, thermal conductivity and density decreased with the increase of glazed hollow bead vol-ume replacement, their relationship was polynomial fitting; the mix proportion with recycled fine aggregate 50% re-placement and the glazed hollow bead 110%volume replacement was the optimized design.关键词
