Orthogonal Test on Large Content of Solid Waste in Building Binder
With the compound system of fly ash and aluminum slag as the main material,activated through ordinary activator,a type of building binder in which wastes is more than 80 percent is studied in the paper.The ratio of the activator is optimized through orthogonal test.Experimental results show that the active component in the solid wastes can be greatly activated under the mixture proportion as following:10% lime,4% gypsum,0.5% sodium carbonate and 0.5% sodium sulfate.The cementing medium has enough strength to meet the requirements in construction engineering.Material of the cementing medium has the advantage of easy availability,low cost and high rate of waste utilization.It will be a kind of green building materials with a great expect.
