国外的生产经验和我们的中间性试验都巳证明,用压蒸工艺生产的灰砂配筋构件具有优良的技术性能,可用以代替水泥砼建筑构件(见本刊1986年第4期)。而一种新产品能否有价值进行开发和推广,则除了技术性能外,还取决于生产这种产品所能取得的经济效益和社会效益。虽然压蒸灰砂加筋硅酸盐制品的经 The foreign production experience and our intermediate tests all prove that the lime sand reinforcement components produced by the pressure steaming process have excellent technical performance and can be used to replace cement concrete components (see the 4th issue of 1986). However, whether a new product can be valued for development and promotion will depend on the economic and social benefits that can be achieved in the production of such products in addition to technical performance. Although the pressure lime sand reinforced silicate products
