复合混凝土空心砌块与建筑节能 杨鼎宜 　赵 　玲 (扬州大学 　扬州 　225009) 　　摘 　要 : 分析了建筑节能的意义 ,并针对混凝土空心砌块存在的热工性能差的问题 ,研制了复合混 凝土空心砌块 。通过对实测结果和计算数据分析表明,两种复合混凝土空心砌块分别达到节能 30 %和节 能 50 %的要求 ,并均具有防裂 、抗渗 、耐久性好 ,易施工 ,造价低廉等特点 ,是一种较为理想的节能型墙体材 料 ,它为混凝土空心砌块的发展开辟了一条新途径 。 　　关键词 : 建筑节能　复合混凝土空心砌块 　保温 　隔热 COMPOUND CONCRETE HOLLOW BLOCKS AND ENERGY SAVING FOR BUILDINGS Yang Dingyi 　Zhao Ling ( Yangzhou University 　Yangzhou 　225009) Abstract : This paper analyzes the significance of energy saving for buildings. The compound concrete hollow blocks have been developed to improve the poor thermotechnical effect existed in normal concrete hollow blocks. Test data and calculations show that the two types of compound concrete hollow blocks have achieved respectively the requirements for energy saving of 30 percent or 50 percent , and also have the advantages of crack prevention , impermeabilit y ,durabilit y ,lower price and easiness in construction. As a relatively ideal wall material of energy saving ,the compound conerete hollow blocks have opened a new way to the development of concrete hollow blocks.
