Abstract

The invention relates to a non-sintered brick prepared from river and lake silt and a preparation process thereof. The brick is prepared from silt, quicklime, an additive, an aggregate, a solidifying agent and an appropriate amount of water. The process comprises dewatering silt, adding the additive and the quicklime, uniformly stirring, standing for a period of time, adding the aggregate and the solidifying agent, performing extrusion-molding, and naturally airing. The process has advantages of effective resource utilization, strong process operability and no secondary pollution. The obtained brick has high compressive strength and flexural strength, and long service life.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a non-sintered brick prepared by using river and lake silt as a main raw material and a specific process. Background technique [0002] Silt is deposited in still water or slow flowing water environment, and formed by biochemical action, its natural water content is greater than the liquid limit, and the natural void ratio is greater than or equal to 1.5 cohesive soil. When the natural water content is greater than the liquid limit and the natural void ratio is less than 1.5 but greater than or equal to 1.0, the cohesive soil or silt is silty soil. In addition, the construction and maintenance of ports, ensuring the flood discharge capacity of rivers, ensuring the smooth flow of waterways, and enhancing the flood storage capacity of lakes all require dredging of rivers and lakes, which will generate a large amount of dredged mud. At the same time, with the...
