小型空心砌块的生产和应用在我国已有较长的历史。近十年来,它的发展尤为迅速,在城乡住宅建筑中发挥了重要作用。几年来的实践证明,小型空心砌块的优越性就在于一个“活”字。“活”就活在可以因地制宜,就地取材。砌块的原材料多种多样,有碎石山砂、卵石河砂、粉煤灰煤渣、钢铁废渣、浮石、煤矸石,等等,真是取之不尽,用之不竭。利用废渣,既节约能源,又保护环境。这是“活”的特点之一。“活”的特点之二就是生产方法灵活。
The production and application of small hollow blocks have a long history in China. In the past ten years, its development has been particularly rapid and has played an important role in urban and rural residential buildings. Practice over the past few years has proven that the superiority of small hollow blocks lies in a “living” word. “Living” lived on the basis of local conditions and made materials locally. The raw materials of the blocks are varied, including gravel and mountain sand, pebble river sand, fly ash coal residue, iron and steel waste residue, pumice stone, coal gangue, and so on. This is inexhaustible. The use of waste residues saves energy and protects the environment. This is one of the characteristics of “living”. The second feature of “living” is the flexible production method.
