Experimental Study on Preparation of Mullite Decorative Materials

The pouring vibration method is adopted to prepare a fireproof, durable and decorative wall panel, whose materials for preparation are mullite, cement, powder, glass beads, cellulose, pigments and waterproofing agent. The test result shows that the greatest dosage of raw materials for preparing decorative plates is mullite : cement : glass beads : powder : cellulose : pigment : waterproofing agent = 100 : 60 : 20 : 5 : 1 : 10 : 5. Under the ratio, the decorative wall panel gained the apparent density of 942kg/m(3), compressive strength of 7.6MPa, flexural strength of 2.3MPa and water absorption of 6.5%.
