1980年10月在我院竣工了一座全部用煤矸石砌块建造的四层住宅楼(见图1)。使用至今,效果良好。砌块是以煤矸石无熟科水泥为胶结料、沸腾炉渣为骨料而制成的。无熟料水泥的配合比为:沸腾炉渣70～75％,生石灰20～25％,石膏5％。外墙采用三排孔空心砌块,长485至1185毫米共有6种规格,高780毫米,厚285毫米,空心率38～440％。内墙采用单排孔空心砌块,长485至1185毫米共有四种规格,高780毫米,厚200毫米,空心率39～48％。为了便于施工,还生产使用了两种内墙手搬砌块,规格为480×240×115毫米,分带孔和实心两种。
In October 1980, a four-story residential building completed with coal gangue blocks was completed in our institute (see Figure 1). Used so far, the effect is good. The block is made of coal gangue without the cooked branch cement as the binder and the boiling slag as the aggregate. The mix ratio of clinker-free cement is: 70-75% of boiling slag, 20-25% of quick lime, and 5% of gypsum. The exterior wall uses three rows of hollow blocks, with a total length of 485 to 1185 mm in 6 sizes, 780 mm high, 285 mm thick, and a hollow rate of 38 to 440%. The interior wall uses single-row hollow blocks, and there are four sizes from 485 to 1185 mm in length. They are 780 mm high, 200 mm thick, and a hollow rate of 39 to 48%. In order to facilitate the construction, two kinds of inner wall hand-moving blocks are also used for production. The specifications are 480×240×115 millimeters, and they are divided into holes and solids.
