摘　　要：目的研究硼泥陶粒混凝土作为低温热水地板辐射供暖系统蓄热层的作法及其性能.方法辽化湖畔花园小区住宅楼工程中,用硼泥陶粒混凝土代替豆石混凝土作低温热水地板辐射供暖系统蓄热层,取暖期内对试验工程进行温度监测实验.结果试验工程混凝土试块强度平均值为27.5 MPa,合格率为100%,厚度均在允许偏差内,合格率100%;外观鉴定混凝土表面无裂缝,并根据温度监测结果画出了取暖期内每天温度随时间变化的曲线图.结论用硼泥陶粒混凝土作低温热水地板辐射供暖系统的蓄热层,与用豆石混凝土相比,减轻了建筑物自重、减缓了传热速度、增强了房间的热稳定性.In order to study the method and its capability of the borax ceramsite concrete as the layer of accumulation of heat of floor radiant heating, the borax ceramsite concrete was used to substitute for pisolite concrete as the layer of accumulation of heat in the floor radiant heating system during the construction of Lakeside Garden Buildings in Liaohua District. 28 days later, the supervising engineers tested the quality of the construction. The temperature detecting experiment for the construction was tested during the period of heat supply and its experimental results were analyzed. The results showed that the average strength of the concrete test cube was 27.5 MPa and the eligible rate was 100 %. There was no crack in the surface of the concrete from the surface appraisal and the construction quality grade was excellent. The temperature graph with the change of time during the period of heat supply was drawn based on the temperature detecting results. After successful experiments, we came to the conclusion that using the borax ceramsite concrete as the layer of accumulation of heat in the floor radiant heating system would reduce the self-weight of the buildings and the speed of heat-spreading compared with pisolite concrete.
