Problems solved by technology

In the building materials industry, some lightweight materials are used more and more. Lightweight materials can reduce the weight of buildings and improve the service life of buildings. Lightweight sand is a calcined material. Lighter, can reduce the weight of building materials, but the production process of light sand in the past is more cumbersome, these are the problems that we need to solve

Abstract

The invention discloses a lightweight sand. The lightweight sand includes, by weight, 15-18 parts of lightweight stone, 1-1.5 parts of inorganic silicate, 1-2 parts of inorganic phosphate, 1-1.5 partsof water, 0.2-0.5 part of iron oxide. Massive calcination time can be reduced by adopting the lightweight stone to make the lightweight sand, and the lightweight stone can be more loose by adding theiron oxide after calcination, so that the making of the lightweight sand can be more convenient, the lightweight sand can be made after crushing is finished, the making flow of the lightweight sand can be simpler, and therefore, tedious steps of directly making the lightweight sand by stone can be avoided, the flow can be simplified, and the efficiency of factories can be higher.

Description

technical field [0001] The invention relates to the technical field of light sand, in particular to a light sand and a manufacturing process thereof. Background technique [0002] With the development of society, buildings are getting taller and taller. In the building materials industry, some lightweight materials are used more and more. Lightweight materials can reduce the weight of buildings and improve the service life of buildings. Lightweight sand is a calcined material. It is lighter and can reduce the weight of building materials, but the production process of light sand in the past was cumbersome, and these are problems that we need to solve. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a light sand and its manufacturing process. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A kind of light sand, its raw...
