Problems solved by technology

[0004] In the market, the quality of various unfired bricks is uneven, which affects the safety and reliability of demolition. Unfired bricks have great requirements on the ratio of raw materials. The raw material formula of burnt bricks and the processing technology of unburned bricks are also different, which is easy to affect the quality of unburned bricks, so it is necessary to design a more reasonable and new production process and raw material formula

Embodiment 1

[0018] Embodiment 1: A kind of non-fired brick made of house demolition waste is prepared through the following method steps:

[0019] First, select the following raw materials according to the number of parts by mass: 40 parts of house demolition powder, 15 parts of yellow sand, 5 parts of cement, 6 parts of livestock hair, 10 parts of calcium oxide, 3 parts of calcium sulfate, 2 parts of sodium sulfate, and 2 parts of sodium hydroxide , 3 parts of water reducing agent, 4 parts of curing agent, 0.03 parts of sodium metaaluminate, 10 parts of water; mix yellow sand, cement and calcium oxide, add water and stir into mortar for later use; mix house demolition powder and calcium sulfate, sodium sulfate, hydrogen Put sodium oxide and sodium metaaluminate into the mortar and stir thoroughly; machine the livestock hair into 0.3cm-long broken hair, fumigate with 5-8% alkaline water for 30 minutes, and then cool naturally. Standby; add the water reducer and curing agent to the raw mat...

Embodiment 2

[0020] Embodiment 2: A burn-free brick made from house demolition waste is prepared through the following method steps:

[0021] First, select the following raw materials in terms of parts by mass: 40 parts of house demolition powder, 18 parts of yellow sand, 5 parts of cement, 7 parts of livestock hair, 10 parts of calcium oxide, 3 parts of calcium sulfate, 2 parts of sodium sulfate, and 2 parts of sodium hydroxide , 3 parts of water reducing agent, 3 parts of curing agent, 0.03 parts of sodium metaaluminate, 8 parts of water; mix yellow sand, cement and calcium oxide, add water and stir into mortar for later use; mix house demolition powder and calcium sulfate, sodium sulfate, hydrogen Sodium oxide and sodium metaaluminate are put into the mortar and fully stirred; the livestock hair is machined into 0.3cm long broken hair, fumigated with alkaline water with a concentration of 5-8% for 35 minutes, and then cooled naturally. Standby; add the water reducer and curing agent to ...

Abstract

The invention discloses a method for making baking-free bricks by means of housing demolition garbage and relates to the technical field of baking-free brick production. The baking-free bricks are obtained after demolition garbage powder, yellow sand, cement, livestock hair, calcium oxide, calcium sulfate, sodium sulfate, sodium hydroxide, a water reducer, a curing agent, sodium metaaluminate and water are smashed, stirred and processed. By making the baking-free bricks by means of housing demolition garbage, baking-free brick making cost and material cost are reduced, the produced baking-free bricks are high in hardness and strength, garbage pollution caused by demolition is reduced greatly, and the using effect of the finished baking-free bricks is obvious.

Description

Technical field: [0001] The invention relates to the technical field of production and processing of non-burning bricks, in particular to a method for making non-burning bricks by using house demolition waste. Background technique: [0002] Burn-free brick is a new type of wall material that uses fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. as the main raw materials without high-temperature calcination. Formula, add coagulant and trace chemical additives in a certain proportion, so that the particle size, humidity, and mixing degree are strengthened with reasonable equipment and technology to achieve the best plastic state, and then pressed by high pressure to make the brick body harden rapidly, the longer the time , the better the effect, the better the practicability of the brick, no need to soak it when building the wall, and the appearance is neat. Because this material has high strength, good durability, standard size, co...
