Limestone and Dolomite Tailings Properties and Bricks Development

Abstract:

The mud-containing and fine-grained tailings of limestone and dolomite, as raw material with poly chem soil binder (PCSB), can be used to produce load bearing bricks by means of preparation, measurement, mixing grind, molding, curing and other processes. The molding process parameters were obtained through the soil test of tailings. The curing strength was proved to be greater than C10-15 from the judging test. PCSB was optimized according to the curing and economic cost. The factors such as dosage form, tailings samples, density and water content were discussed in the orthogonal test. The mix of PCSB: tailings: process water =1:9:0.95 in quality was verified in the product test.
