Abstract

The invention discloses a construction engineering mud brick and a manufacturing method thereof, and relates to the technical field of building bricks, the construction engineering mud brick comprisesthe following raw materials by weight: 60-72 parts of mud, 5-10 parts of rubber powder, 2-6 parts of mica powder, 3-7 parts of mine tailings, 2-5 parts of modified composite fiber, 4-8 parts of a modifier, and 1-3 parts of sulfonated lignin. The preparation method comprises the following steps: collecting slurry and dehydrating; adding mica powder, mine tailings and a modifier into the slurry toobtain a mixture A; mixing the modified composite fiber, rubber powder and sulfonated lignin to obtain a mixture B; mixing the mixture A and the mixture B; and paving a glass fiber net on the surfaceof the green brick by using film coating equipment, and maintaining. The mud brick has the beneficial effects that mud is recycled, resources are saved, damage to the environment is reduced, economicbenefits are generated, and the prepared mud brick has good pressure-resistant and fracture-resistant effects and has corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of building bricks, in particular to a construction engineering mud brick and a manufacturing method thereof. Background technique [0002] In recent years, with the continuous heating up of urban construction, geotechnical engineering construction (such as survey drilling, cast-in-situ pile and underground diaphragm wall construction, shield construction, anchor engineering, hydrological well, water-stop curtain, trenchless construction, etc.) According to official data, the city produces about 3 million tons of engineering mud every year, and the actual data may far exceed this amount. A large amount of waste mud generated during project construction deteriorates the construction environment, increases construction difficulty, and affects construction progress; on the one hand, diluted discharge may cause blockage of sewage pipes, and at the same time, long-term accumulation of waste mud seeps into the gro...
