Non-fired and non-autoclavedtitanium gypsum brick and preparation method thereof
The invention discloses a non-fired and non-autoclavedtitanium gypsum brick and a preparation method thereof. The titanium gypsum brickcomprises components in percentage by mass as follows: 24.1%-32.3% of titanium gypsum, 52%-63.8% of aggregate, 11.2%-18.5% of cement/mineral powder and 0.8%-1.0 % of an additive, wherein the additive is a mixture of anhydrous sodium sulfate, alums and a curing agent; and the aggregate is one or more of industrial mineral slag, crushed stone and river sand. The preparation method of the titanium gypsum brick comprises steps as follows: S1, slurry type titanium gypsum is extruded and stirred to form hydraulic slurry; S2, the extruded and smashed titanium gypsum and the aggregate are mixed and stirred for 2-4 minutes; S3, a material prepared in S2 is mixed with the additive and the cement/mineral powder and stirred for 1-3 minutes; S4, extruding forming is performed, consistency of the water content in different positions of a hopper is kept through spraying and watering, and the mass ratio of water to the material prepared in the S3 is 1:(32:40). Raw materials are easy to prepare, main performance parameters meet the national standard, the preparation method is simple and easy to operate, the efficiency is high, energy consumption is reduced due to no need of firing and autoclaving, and environmental pollution is reduced.
