preparation example Construction

[0023] The preparation method of the above-mentioned anti-impact residual mud slag soil regeneration unburned brick of the present invention comprises:

[0024] A. Collect residual sludge, crush, and then sieve and wash with water to obtain three parts of particles: 5mm-10mm, 2.5mm-5mm, and 0.16-2.5mm;

[0025] B. Fully mix the cement, residual mud and slag, and basalt fiber, add the required water, and continue to stir evenly;

[0026] Among them, the dosage of each component is as follows: Coarse particles of residual sludge 450-950kg / m 3 , Medium particles of residual mud and slag 450~950kg / m 3 100~700kg / m of fine particles of residual mud and slag 3 , Cement 100~550kg / m 3 , Basalt fiber 1~7.5kg / m 3 And water 50~200kg / m 3 ;Preferably, the coarse particle of residual sludge is 600~800kg / m 3 600~800kg / m3 for medium particles of residual mud and slag 3 , Fine particles of residual sludge 200~600kg / m 3 , Cement 200~400kg / m 3 , Basalt fiber 2~5kg / m 3 And water 80~150kg...

Embodiment 1

[0035] The residual sludge is collected, crushed, and then screened and washed into three parts: coarse particles of 5 mm to 10 mm, medium particles of 2.5 mm to 5 mm, and three parts of 0.16 to 2.5 mm. Weigh the corresponding raw materials according to the mixing ratio: 400kg of cement, 500kg of coarse particles of sludge, 800kg of medium particles of sludge, 500kg of fine particles of sludge, 100kg of water, and 4kg of basalt fiber. Thoroughly mix the coarse, medium and fine particles of cement, sludge and slag and basalt fiber, add the required water, and continue to stir evenly. Then take an appropriate amount of mixture, add it into the mold, put it on a press, pressurize it under 40MPa pressure, and finally maintain it naturally.

[0036] The performance indicators of impact-resistant residual mud and slag soil recycled unburned bricks were tested, including testing their appearance quality, density, 28d compressive strength, and fracture energy. The results are shown in...

Abstract

The invention relates to an anti-impact residual clay residue regenerative baking-free brick and a preparation method thereof. The anti-impact residual clay residue regenerative baking-free brick is mainly prepared from the following components: the residual clay residue with gravel soil as a main component, cement and basalt fibers. According to the anti-impact residual clay residue regenerativebaking-free brick disclosed by the invention, by means of spatial mesh distribution doped with the basalt fibers, the development of cracks is controlled, impact resistance is improved, and all performance indicators of the baking-free brick can be satisfied; the anti-impact residual clay residue regenerative baking-free brick is suitable for a protecting structure for masonry engineering; meanwhile, by recycling the residual clay residue, the pollution to the environment is reduced; in addition, the preparation method has the advantages of simple technology, high treatment efficiency, high treatment quantity, good field application effect, and better economic benefit and social benefit; novel building materials which use the residual clay residue and other non-clay materials as main raw materials are developed, and important practical significance is achieved; huge output of the novel building materials also provides a broad prospect for the production of the baking-free bricks.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an impact-resistant residual mud slag recycled unburned brick and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's construction industry and rail transit projects, the utilization of underground space has increased rapidly, resulting in a large amount of engineering debris, which seriously restricts urban development. A large amount of residual sludge is the most important solid waste every year. How to deal with and rationally utilize such a huge residual sludge has become an important problem faced by construction companies and government environmental protection departments. It is of great significance to carry out economical transportation construction. And the intensity of present burn-free brick is low, and impact resistance is poor. Contents of the invention [0003] The purpose of the pr...
