Abstract
The invention discloses an iron tailing slag brick. A brick body is prepared by mixing iron tailing slag which is used as a main raw material, and macadam, cement, a curing agent and water in a weight ratio; the preparation method comprises the following steps of: mixing 75 to 80 weight percent of iron tailing slag, 10 to 12 weight percent of cement, 2 to 5 weight percent of curing agent, 3 to 13 weight percent of macadam, and 8 to 12 weight percent of water; mixing and stirring, and forming under static pressure; and demoulding and curing to prepare the brick body. The iron tailing slag brick has the advantages of simplicity in preparation and convenience in operation.
Description
Technical fieldThe present invention relates to a kind of method, especially a kind of brick-making method.
Background technologyKnown, the iron tailings slag brings very large problem to modern society, and 1, tailings impoundment need to take a large amount of soils, causes land wastage; 2, contaminate environment; 3, Tailings Dam moves the fund waste that causes; 4, potential safety hazard.But present iron tailings slag recycling rate is lower, can't address the above problem at all.
Summary of the inventionThe purpose of this invention is to provide a kind of iron tailings slag brick and manufacture method that the iron tailings slag is made the brick body that recycle.
Brick body of the present invention is mixed with rubble, cement, solidifying agent, water by weight proportion take the iron tailings slag as main raw material; Its manufacture method is, ingredients by weight is than being iron tailings slag 75～80%, cement 10～12%, and solidifying agent 2～5%, rubble 3～13%, water 8～12%, the brick body is made in hydrostatic profile, demoulding maintenance behind the mix and blend.
During use, the iron tailings slag is mixed according to a certain percentage with cement, rubble, solidifying agent, water, mix and pour in the adobe, adopt the method for hydrostatic profile, demoulding maintenance, prepare the MU15 level iron tailings brick that is of a size of 240mm*115mm*53mm.
Compared with the prior art, beneficial effect of the present invention is: prepare simply, easy to operate, can effectively utilize the iron tailings slag, reduce environmental pollution, the saving fund.
EmbodimentBrick body of the present invention is mixed with rubble, cement, solidifying agent, water by weight proportion take the iron tailings slag as main raw material; Its manufacture method is, ingredients by weight is than being iron tailings slag 75～80%, cement 10～12%, and solidifying agent 2～5%, rubble 3～13%, water 8～12%, the brick body is made in hydrostatic profile, demoulding maintenance behind the mix and blend.
Embodiment 1:
Select by weight iron tailings slag 75%, cement 10%, solidifying agent 4%, rubble 3%, water 8% mixes, and wherein, the iron tailings slag mainly contains the high-silicon type iron tailings slag of SiO2 and Fe2O3, and solidifying agent is the TLS02 solidifying agent, and forming pressure is 18MPa.Mixed raw material is poured in the adobe, after hydrostatic profile, demoulding maintenance, made the MU15 level iron tailings brick that is of a size of 240mm*115mm*53mm.
