Regenerated sludge muck brick and preparation method thereof

Abstract

The invention provides a regenerated sludge muck brick and a preparation method thereof. The regenerated sludge muck brick is prepared from the following raw materials in parts by weight: 50-90 parts of soil, 5-45 parts of aggregate, 5-30 parts of cement and 1-20 parts of a soil stabilizer, wherein all the raw materials are scientifically proportioned, the regenerated sludge muck brick is obtained through stirring, aging, mixing, pressing, soaking and curing, the average density of the prepared regenerated sludge muck brick is 4.26 g / cm<3>, the initial setting time is 116min, the compressive strength is 23.69MPa, the breaking strength is 12.64MPa, and the water absorption rate of a single block is 10.1%.

AI Technical Summary

Problems solved by technology

[0002] With the continuous advancement of urbanization in our country, some new problems inevitably arise. On the one hand, the construction solid waste generated in the process of urban construction, renovation, and demolition is also increasing, such as building foundation mud, construction waste, and subway shields. Structural mud, river silt, water plant sludge, industrial sludge, incineration garbage and other general solid wastes are piled up in large quantities. River course and other silt is one of the important types of urban solid waste. A large amount of inorganic and organic matter is accumulated in the river mud, which becomes a secondary pollution source through the diffusion and exchange with the overlying water body. The dredging of dense water networks such as canals, rivers and lakes in my country will produce a large amount of silt. And with the planning and upgrading of the river channel, more river silt will be produced, so the silt will be recycled to make finished bricks. However, in the current brick-making technology, due to the difference between silt and sand, it is easy to form clods when it meets water. , causing the curing agent and cement to fail to enter the middle of the soil block, resulting in uneven mixing of the raw materials, making the finished bricks less effective
