蒸养(压)灰渣砖是利用工业废渣为原料制作而成的一种墙体材料。无产阶级文化大革命以来,灰渣砖的生产有了很大发展,产品的产量和质量也有较大的提高。最近,有些单位向本刊编辑组了解有关灰渣砖物理力学性能测试方法。由于灰渣砖的材性检验方法目前尚无国家标准(正在筹备制订),因此我们特请北京市建筑材料科学研究所撰文解答这个问题,供读者参考。
Steam curing (pressing) clinker brick is a kind of wall material made from industrial waste as raw material. Since the proletarian cultural revolution, the production of ash bricks has been greatly developed, and the output and quality of products have also been greatly improved. Recently, some units have read about the testing methods for physical and mechanical properties of ash bricks. As there are no national standards for the testing of wood properties of ash bricks (under preparation for preparation), we hereby invite the Beijing Institute of Building Materials Science to answer this question for readers’ reference.
