preparation example Construction

[0032] In yet another embodiment of the present invention, a method for preparing microwave-fired muck bricks is provided, which includes the following steps: stirring water and cementitious materials evenly to obtain a mixture; wherein the cementitious materials are dregs and ferroferric oxide A mixture of powders; aging the mixture and pressing the aged mixture into adobe; microwave drying the adobe to obtain a dry adobe; roasting the dried adobe in a microwave and then cooling to obtain a microwave-fired slag brick.

[0033] Concretely, the specific method of mixing the water and the cementitious material evenly to obtain the mixture is as follows: firstly weigh the slag and ferric oxide powder in proportion and stir evenly to obtain the cementitious material, preferably, the cementitious material is calculated by mass percentage Including: 80% to 95% of slag and 5% to 20% of ferric oxide powder.

[0034] A certain proportion of water is added to the gelling material and st...

example 1

[0043] Step 1: Scale the slag and ferric oxide powder and mix together initially to obtain a cementitious material. Wherein, by mass percentage, it includes: 90% of slag and 10% of ferric oxide powder. Add a certain proportion of water into the gelling material and stir evenly to obtain a mixture, wherein the mass ratio of water to the gelling material is 1:2.

[0044] Step 2: Aging the mixture for 7 days, and then pressing the aged mixture into adobe through a 1300T press.

[0045] Step 3: Place the adobe in an industrial microwave oven, dry it under a microwave power of 800W for 17 minutes, and then cool it down to obtain a dry adobe.

[0046] Step 4: Place the dry brick in an industrial microwave oven, first bake it at a microwave power of 1800-2000W for 15-17 minutes, then continue to bake it at a microwave power of 2800-3000W for 20-22 minutes, and then cool it down.

example 2

[0048] Step 1: Scale the slag and ferric oxide powder and mix together initially to obtain a cementitious material. Among them, by mass percentage, it includes: 85% of slag and 15% of ferric oxide powder. Add a certain proportion of water into the gelling material and stir evenly to obtain a mixture, wherein the mass ratio of water to the gelling material is 1:2.

[0049] Step 2: Aging the mixture for 10 days, and then pressing the aged mixture into adobe through a 1300T press.

[0050] Step 3: Place the adobe in an industrial microwave oven, dry it under a microwave power of 900W for 16 minutes, and then cool it down to obtain a dry adobe.

[0051] Step 4: Place the dried brick in an industrial microwave oven, first bake it at a microwave power of 1900W for 16 minutes and then cool it, then bake it at a microwave power of 2900W for 21 minutes and then cool it to obtain a microwave fired slag brick.

Abstract

The invention belongs to the field of building materials, and discloses a microwave-fired muck brick and a preparation method thereof. The microwave-fired muck brick is prepared from the following raw materials: water and a cementing material, wherein the mass ratio of the water to the cementing material is (3-5): 10; and the cementing material is prepared from the following components in percentage by mass: 80 percent to 95 percent of muck and 5 percent to 20 percent of ferroferric oxide powder. The preparation method comprises the steps of uniformly stirring the water and the cementing material to obtain a mixture, wherein the cementing material is a mixture of muck and ferroferric oxide powder; aging the mixture, and pressing the aged mixture into a green brick; carrying out microwave drying treatment on the green brick to obtain a dried green brick; and carrying out two-stage microwave roasting on the dried brick blank to obtain the microwave-fired muck brick. The problems of energy waste and environmental pollution caused by the fact that traditional raw material muck brick can only be roasted with open fire are effectively solved, the production cost of the muck brick is reduced, the production period is shortened, and the production efficiency of the brick is improved.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a microwave fired slag brick and a preparation method thereof. Background technique [0002] With the development of the construction industry, the demand for bricks among building materials is increasing day by day. At present, building bricks generally need to consume a large amount of muck when making bricks, which leads to occupying and destroying a large area of ​​cultivated land. In addition, building bricks need to be fired with an open flame, and the entire firing process is a waste of resources and consumes too much energy. At the same time, the discharge of pollutants is unavoidable due to open fire firing, which is not conducive to environmental protection. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of waste of resources, excessive energy consumption and pollution of ecological environment in the brick-maki...
