云南高岭质煤矸石建筑墙地砖的研制

Study on preparation of walltile with kaolin coal gangue by cross design technique

利用正交设计技术对云南高岭质煤矸石建筑墙地砖生产工艺进行了优化设计。经过初步研究找到了影响煤矸石墙地砖质量的主要因素 ,即颗粒级配是影响煤矸石建筑墙地砖湿膨胀性、吸水率。

The optimum design of the process of producing build wall tile with kaolin coal gangue was carried out by cross design technique. The main factor affecting the quality of coal gangue wall tile was found by a series of tests, which was particle gradation.
