贵州“八山一水一分田”,粘土缺乏。但石灰岩、页岩、砂岩等资源丰富,开采方便。同时,还有大量的煤矸石、粉煤灰、电石渣等工业废料。为了节约土地,我省大力发展各种非粘土承重墙体材料,生产了混凝土空心砌块、混凝土空心砖、页岩烧结砖、蒸压(养)灰砂砖、烧结煤矸石砖、蒸压(养)粉煤灰砖、煤渣砖、煤渣混凝土砌块、电石渣砖、电 In Guizhou, there is a lack of clay in the “eight hills and one water and one field”. However, rich resources such as limestone, shale and sandstone are easy to exploit. At the same time, there are a large number of industrial waste such as coal gangue, fly ash and carbide slag. In order to save land, our province vigorously developed all kinds of non-clay bearing wall materials and produced concrete hollow blocks, hollow concrete bricks, shale sintered bricks, autoclaved (ceiling) sand-lime bricks, sintered coal gangue bricks, and autoclaved ) Fly ash bricks, coal clinker bricks, cinder concrete blocks, calcium carbide slag bricks, electricity
