Abstract
The invention discloses a plateau environment-friendly burning-free raw earth brick and a preparation method thereof. The burning-free raw earth brick includes aggregate, cement, phosphogypsum, raw soil, river sand, water glass, aluminum sulfate, sodium aluminate, aluminate Composed of calcium, alcohol, calcium chloride and sodium acetate, the preparation method includes material preparation, mixing, molding and vibration. The invention uses solid waste construction waste concrete to replace natural stone, phosphogypsum does not need to be pretreated, and consumes a lot, and it is mixed and molded at normal temperature and pressure, the process is simple, and it is beneficial to reduce energy consumption and protect the environment. The content is reduced, reducing the consumption of raw soil. The unfired raw earth bricks prepared by the invention can meet the strength requirements of construction projects for blocks, and the test blocks have strong frost resistance, and are suitable for use in plateau construction and loess treatment projects; at the same time, the material is suitable for loess water and soil in this area. The control of loss, slope instability, and foundation settlement has practical application value.
Description
technical field [0001] The invention belongs to the technical field of non-burning brick production, and particularly relates to a plateau environment-friendly non-burning raw earth brick and a preparation method thereof. Background technique [0002] Raw earth construction refers to construction activities in which unsintered original earth materials are the main materials. Since ancient times, raw soil has been a global building material. Because of its convenience of local materials, low cost and good thermal performance, more than 1 / 4 of the world's people still live in raw soil dwellings. In my country, there are at least 60 million people who still live in various types of raw soil dwellings, and they are all over the provinces. Mainly concentrated in the underdeveloped western regions such as Gansu, Xinjiang, Yunnan and Tibet. Affected by the acquisition of residential building materials, raw soil buildings are mainly distributed in areas with rich soil, hard soil a...
