Outer wall board for building

Abstract

The invention relates to the technical field of building materials, in particular to an outer wall board for a building. The outer wall board consists of fly ash concrete for the building and steel reinforcement framework, and an inner layer of the outer wall board is formed by pouring the fly ash concrete on the steel reinforcement framework. Based on the prior building board structure, the fly ash is used as a main filling raw material, so the outer wall board of the building prepared by the process has the characteristics of environmental protection, energy conservation, heat insulation and remarkable fire retarding effect, can further reduce pollution to the social environment, change large amount of fly ash into valuable, can well reutilize the fly ash, and simultaneously save large amount of investment. Because the manufacturing cost of a product is low and the process is simple, the marketing price is comparatively low; and once the outer wall board is input into the market, the outer wall board can be widely applied to the building industry, so the market prospect of the outer wall board is quite remarkable, and the outer wall board is preferably greatly popularized and used and has considerable broad economic benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building exterior wall board. Background technique [0002] As we all know, due to the current rapid development of the construction industry, the demand for construction concrete is also increasing rapidly. At present, the utilization rate of industrial waste residues in our country is quite low, and the vast majority of industrial waste residues cannot be fully reused, resulting in serious waste. At present, there are also some various building materials made of fly ash as the base material in the domestic market. This is because fly ash has a wide range of sources, low cost, high compressive and flexural strength, and relatively Environmental protection, so the use of fly ash to make building materials is a very promising scientific research topic, especially for building concrete and building boards.
