Underground engineering construction sludge environment-friendly baking-free brick and production method thereof

The invention relates to the field of buildings, in particular to an underground engineering construction sludge environment-friendly baking-free brick and a production method thereof. The environment-friendly baking-free brick is prepared from the following raw materials in parts by weight: 60%-70% of underground engineering construction sludge, 8%-10% of underground engineering construction solid residues, 10%-15% of CaO, 6%-8% of 425 ordinary Portland cement, 0.1%-0.5% of A type biological enzyme and 5%-10% of H2O. According to the environment-friendly baking-free brick for the underground engineering construction sludge, the problem that the environment is seriously affected due to the fact that traditional underground engineering construction sludge treatment needs transportation, stacking, landfill and other methods is solved, the underground engineering construction sludge is well utilized in a recycling, harmless and reducing mode, waste is treated and utilized, and the self value is exerted, resource
