聚醋酸乙烯乳液制高炉渣墙体砖的研究

Study on Preparation of Wall Brick from the BF Slags Containing Titania and the PVAC

以含钛高炉渣为集料,聚醋酸乙烯为胶凝材料,辅以添加剂制备了一种新型墙体砖。结果表明:墙体砖中高炉渣掺量可达70%以上,其外观质量、强度性能、体积密度、吸水率和干燥收缩性能等指标均达到或超过砌墙砖的基本要求。

By using the blast furnace （BF）slag containing titania to replace clay as aggregate,the PVAC as cement , and add an additive , a new wall brick was prepared , in which BF slag content is over 70%. The main properties of the wall brick such as exterior quality, strength character,volume density, the water absorption and dry contractibility satisfied the basic requirements for wall brick.
