Problems solved by technology

This kind of brick uses cinder as the main raw material, but due to the use of cement in the proportioning, the cost is high, so the water absorption rate is low and the surface is smooth, so the plaster on the brick wall is not easy to stick during construction, giving Construction caused great difficulties
No method for making bricks or blocks using steel slag as the main raw material and no cement in the proportioning was found after searching

Embodiment Construction

[0004] The concrete implementation production condition of the present invention and control condition are as follows:

[0005] Production equipment and conditions: ball mill, mixer, vibrating table, curing room, drying room, storage yard.

[0006] Manufacturing method and control conditions:

[0007] (1) Raw material preparation: Grind the slag with a ball mill, and sieve the steel slag with a 0.8mm square hole sieve.

[0008] (2) Weigh the raw materials according to the weight ratio, put them into the mixer at one time and stir evenly, and the stirring time is 3 minutes.

[0009] (3) Take out the mixed material that has been stirred and put it into the mold, vibrate and shape it on a vibrating table; or use extrusion molding, and put the mixed material into the extrusion trough to form after stirring.

[0010] (4) Place the molded brick or block joint mold indoors for 5 hours, then remove the wax, and enter the curing room for 14 days or 21 days for curing. The former can ...

Abstract

The production method of cement-free steel slag brick and block adopts the waste slag produced by smelting steel as main raw material, and adds lime, blast-furnace slag and water, and adopts the processes of stirring, forming and curing at normal temp. and normal pressure to produce the invented products. The invented steel slag brick and block can be completely substituted for traditional clay brick, can be used as raw material for making enclosure wall and bearing wall.

Description

Technical field: [0001] The invention relates to a method for manufacturing cement-free steel slag bricks and blocks. Background technique: [0002] At present, the most common coal brick in the village construction market is to use industrial waste to make bricks to replace traditional clay bricks. This kind of brick uses cinder as the main raw material, but due to the use of cement in the proportioning, the cost is high, so the water absorption rate is low and the surface is smooth, so the plaster on the brick wall is not easy to stick during construction, giving Construction caused great difficulties. After retrieval, no method for making bricks or building blocks with steel slag as the main raw material and no cement is found in the proportioning. Invention content: [0003] The object of the present invention is to provide a method for manufacturing cement-free steel slag bricks and blocks. The purpose of the present invention is achieved through the following tech...
