Problems solved by technology

[0004] At present, the clay and wall building materials using cement as the gelling agent used in the construction field have the advantages of high strength and good durability, but their large volume, poor sound insulation and heat insulation performance make them widely used. restricted
At the same time, there are high resource and fuel consumption, complicated process, and easy pollution to the environment.
The texture of the made building materials is relatively loose, the strength is not enough, and some raw materials are in stock, which is not suitable for large-scale production due to the limitation of geographical conditions.

Abstract

The invention discloses an environment-friendly building material and a manufacturing method thereof. The environment-friendly building material is characterized by comprising the following raw materials in parts by weight: 50 to 55 parts of cement, 35 to 45 parts of fly ash, 20 to 30 parts of steelmaking slag, 30 to 40 parts of plant fiber, 5 to 8 parts of sepiolite, 4 to 6 parts of bentonite, 8to 12 parts of quick lime, 0.6 to 0.8 part of magnesium silicate, 2.3 to 2.5 parts of a wetting agent and 1 to 2 parts of a functional additive. According to the prepared building material, the plantfiber, industrial waste gas, coal slag and steelmaking waste slag are utilized, and the waste is turned into the valuable; the sepiolite and other components are added, so the material has the effectsof heat preservation and sound insulation, and the material has low heat conductivity coefficient and good energy-saving effect; and the compressive strength and the impact strength of the finished wall building material are very high, so the building material is an environment-friendly building material.
