Abstract
A method for producing lightweight porous thermal insulation bricks with silicon tailings belongs to an inorganic material technology. The invention is characterized in that a prescribed amount of tailings is mixed and ground with a small amount of initiator and excitant, then water and firming agent are added to obtain slurry; foams with proper elasticity is prepared through chemical reaction under ambient temperature, which will be added into the slurry in order to make foamy slurry; and finally the foamy slurry are solidified in moulds and lightweight porous thermal insulation bricks can be obtained following a proper curing period. The utilization rate of tailings proves to be high in the invention, amounting to 65 percent as a minimum for porous bricks. The thermal insulation bricks made through ambient temperature forming, reaction and solidification has advantages of light weight, porousness, thermal insulation, which can be widely employed in the construction of non load-bearing walls and roofs. The invention can allow effective utilization of tailings, reduce the environmental pollution as a result of tailings stock and improve the economic effects in the mining sector.
