Preparation of Unburned Brick from the High Titania Blast Furnace Slag and Styrene-Acrylate Emulsion
Abstract:
The unburned brick was prepared by using the high titania blast furnace slag as an aggregate, styrene-acrylate emulsion as cementing materials and two admixtures. Factors such as amounts of admixtures and styrene-acrylate emulsion, forming pressure and curing time on the properties of the products were studied. The optimal process conditions for preparing the brick sample were as follows: mass fractions of the slag, styrene-acrylate emulsion, admixture 1, admixture 2 and water were respectively 70%, 8%, 8%, 10% and 4%, forming pressure 30 MPa, curing time 7 d. The properties of the brick sample prepared under these process conditions are better than that of MU 25 in GB / T 2542 - 2003.
