Abstract

The invention relates to a lightweight flame-retardant concrete-based inner wall material and a preparation method thereof and belongs to the field of building materials. The lightweight flame-retardant concrete-based inner wall material is a solid brick body. The solid brick body is composed of an outer brick body and an inner brick body coated with the outer brick body. The inner brick body is prepared from foamed concrete. The outer material is a flame-retardant material. The foamed concrete is composed of a solid component and additional components. The solid component is composed of 40-60% of Portland cement and 40-60% of fly ash and has a water-cement ratio of 0.4-0.8. The additional components comprise a plant foaming agent and a water reducing agent. The use ratios of the plant foaming agent and the water reducing agent to the solid component are 1-2% and 1.5-3%. The wall material can meet the demand of general household refractory wall materials, has light weight, satisfies the bearing requirements and reduces the weight.

Description

technical field [0001] The invention relates to a lightweight flame-retardant concrete-based interior wall material and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Fire is one of the more common disasters at present. With the rapid development of China's domestic real estate industry, the height of residential buildings is getting higher and higher. How to avoid large fires is one of the issues that people pay more and more attention to. one. One of them is not only in the open fire area of ​​the family, but also the fire prevention needs of the kitchen. When decorating the interior walls of the kitchen, it is especially necessary to choose suitable fireproof materials. This type of material has a lower level of fire resistance than industrial production; at the same time, for the convenience of handling, the weight should be as low as possible. Therefore, it is necessary to have both lightweight and flame-retar...
