Abstract

The invention provides a baking-free brick. The baking-free brick is prepared from the following raw materials in parts by weight: 800-1000 parts of building residue soil; 200-300 parts of rice fieldstraw; 80-120 parts of cement; 22-30 parts of slaked lime; 25-35 parts of gypsum; 8-12 parts of a curing agent; 3-5 parts of an active agent; 1-3 parts of a weather-resistant agent; 100-150 parts of water. Sodium lignosulfonate is a natural high-molecular polymer and an anionic surfactant, has very strong dispersing capacity, and is suitable for dispersing solids in an aqueous medium. The sodium lignosulfonate can be adsorbed on the surface of various solid particles and can be used for metal ion exchange. The sodium lignosulfonate is used as a dispersing agent and a wetting agent, and is mixed with a soil body to generate a series of physical and chemical reactions, and a thin layer of water film wrapping the surface of each fine particle is removed so that the engineering property of thesoil body is changed, and the strength and the water resistance of the baking-free brick are effectively improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection building materials, in particular to an unburned brick and a preparation method thereof. Background technique [0002] With the rapid development of Chinese cities, the bottlenecks restricting urban development are becoming more and more obvious while the scale of cities is expanding. A large amount of muck will cause many problems during the standby period. For example, the problem of the storage site of muck. A large amount of muck needs a lot of space. In the past, the storage point was chosen in the suburbs, which not only destroyed the cultivated land, but also caused damage to the local ecological environment. influences. In addition, there is the problem of air pollution. The dust in the muck enters the air with the wind, affecting the air quality of the city. If these slags continue to be dumped, landfilled or used as road subgrade filling, it will not only occupy a larg...
