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.

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
