利用煤矸石制造空心砖的研究

Study of Using Coal Gangue to Make Hollow Bricks

利用煤矸石制造空心砖，实现了制砖不用粘土，烧砖不用燃料，其社会环境，经济效益均超过了粘土实心砖。

In this paper, production of hollow bricks can be realized by way of using coal gangue as raw materials without clay and fuel. The produced hollow bricks with the technology are superior to the solid clay bricks in terms of environment and economic results.
