Abstract
A method for producing imitation stone from stainless steel slag belongs to the field of integrated utilization of resource. Raw materials comprise 25-35 weight parts of cement, 55-75 weight parts of stainless steel slag and 17-20 weight parts of water. The method comprises steps of: accurately weighing the raw materials; adding water in a mixer, and adding cement with stirring; then successively adding cement and stainless steel slag, and stirring uniformly; casting into a die for a vibratory compaction; finishing a surface; hardening naturally; demoulding; maintaining at a constant temperature of 20+/-1 DEG C, a constant humidity of 95%+/-3% for 7 days to obtain a finished product. The product has a compressive strength of 73 MPa, a rupture strength of 8.3 MPa, a wearing strength of 1.5 and a water absorption of 9.2%.
Description
Technical field
The present invention relates to a kind of method of utilizing stainless steel slag to make imitative stone material, belong to the comprehensive utilization of resources field.
Background technology
Along with growing continuously and fast of domestic iron and steel output, metallurgical slag rolls up, and the pressure that iron and steel enterprise is handled is more and more heavier, also brings huge load for environment, how to use slag, turns waste into wealth, and is our urgent problem.Therefore, the research and utilization stainless steel slag is made imitative stone material, realizes energy-saving and emission-reduction, turns waste into wealth.
Summary of the invention
In order to improve the utilization ratio of waste resource, the present invention provides a kind of method of utilizing grain slag to make imitative stone material.
Raw material of the present invention is a cement by proportion by weight: 25～35 parts; 55～75 parts of stainless steel slags; Water: 17 ~ 20 parts;
Accurately above-mentioned each raw material of metering at first adds entry in stirrer, under whipped state, adds cement; Stainless steel slag stirs then, is poured into vibratory compaction in the mould; Refacing, after the air-set, the demoulding; 20 ± 1 ℃ of constant temperature, under the condition of constant humidity 95% ± 3%, maintenance became product in 7 days.
Its imitative stone material performance of products is: ultimate compression strength is 65 ~ 75Mpa, and folding strength is 7 ~ 9 Mpa, fastness to rubbing 1.1～2.1, water-intake rate 8.9 ~ 9.6%.
The present invention has effectively utilized stainless steel slag, has improved the utilization ratio of waste resource.
Embodiment
Specify embodiment of the present invention below in conjunction with embodiment, but embodiment of the present invention is not limited to following embodiment.
Embodiment:
(1) by the weighing of following raw materials quality part proportioning: 25 parts of cement, 75 parts of stainless steel slags, 19 parts in water.
(2) in stirrer, add entry, under whipped state, add cement, and then add stainless steel slag, stir.
(3) be poured in the mould, vibratory compaction, refacing, after the air-set, the demoulding, maintenance becomes product.20 ± 1 ℃ of constant temperature, maintenance is 7 days under the condition of constant humidity 95% ± 3%, and its performance of products is: ultimate compression strength is 73Mpa, and folding strength is 8.3 Mpa, fastness to rubbing 1.5, water-intake rate 9.2%.
Raw material in the foregoing description is 30g for every part.
