花岗石废弃物在墙地砖中的应用

Application of Granite Trash in Production of Wall and Floor Tiles

将几种花岗石粉末或碎料作为主要原料应用在建筑用墙地砖生产中。研究高岭土、熔剂含量对试样性能的影响 ,分析花岗石废弃料在建筑用墙地砖生产中的应用可能性 ,探讨原料成分定量化等问题。试验结果表明 :含熔剂 2 5 %～ 35 % ,高岭土含量 15 %～ 35 %时 ,4 5 %左右的样品机械强度、吸水率等性质符合或超过墙地砖质量要求。部分样品抗冲击强度大于 2 0次、吸水率几乎为零 ,具有优异的抗冻溶性能 ,可作为无釉地砖用于寒冷地区及潮湿地区。

The feasibility of using granite trash as a main material for production of wall and floor tiles was discussed in this article.The influence of kaolin and flux contents on sample performance was analyzed.Experimental results showed that some samples containing 25%～35% flux and 15%～35% kaolin possess satisfactory performance,such as water absorption and mechanical strength,even surpass the demands of wall and floor tiles.The part of samples dent resistance more than 20 times and water absorption near to zero could be used as no glazed tile in harsh and humid regions.
