我国已确定到2000年实现建筑节能率50％的目标，这意味着建筑节能材料市场今后几年需要大量优质可靠、节能效果显著以及价格低廉的产品。建筑节能的重要环节是墙体节能，目前我国应大力开发和生产墙体绝热材料．使其能够提高墙体热阻，降低墙体传热系数c绝热墙体材料由轻骨料、
China has already established a target of achieving a 50% energy saving rate for buildings by the year 2000. This means that in the next few years, the building energy-saving materials market will require a large number of products with high quality and reliability, significant energy saving effects, and low prices. The important part of building energy conservation is the wall energy conservation. At present, China should vigorously develop and produce wall thermal insulation materials. To make it possible to increase the thermal resistance of the wall and reduce the heat transfer coefficient of the wall. c The material of the thermal insulation wall is made of lightweight aggregate,
