Problems solved by technology

[0003] Although there are many types of fire-proof insulation materials with combustion performance of Class A, due to various reasons, none of them have yet become the mainstream of the market.
The restrictive factors are: 1. Insufficient mass production: Many products consume natural resources, and due to their inherent market, the market share for new building exterior wall materials is seriously insufficient
2. Low cost performance: The energy-saving transformation of my country's construction industry requires a huge amount of thermal insulation materials, and many materials are expensive
3. High energy consumption in production: Many of the materials need to be remelted and fiberized for raw materials. These processes will generate a lot of waste water, waste gas, and consume a lot of energy. It is a high energy consumption and high pollution industry. The overall development trend of the
4. Technical defects: manifested in product bulk density, thermal conductivity, tensile strength, water absorption, binder dosage, waterproof additives and construction conditions, etc.
5. Long marketization cycle: new plant construction requires large investment, long cycle, technical difficulty, and high operational requirements
[0006] However, the production of this kind of foam concrete is still in the scale of manual workshop production.
The "continuous production method of foam concrete" of the present invention solves the problems of unstable quality, low production efficiency, poor working environment, large workshop area, large project construction investment, high product cost and inability to achieve standardization in the production of foam concrete by hand workshops Various disadvantages such as production will greatly improve and enhance the production method and scale of foam concrete

Abstract

The invention discloses a continuous production method for foam concrete and belongs to the technical field of building materials. The method is characterized in that concrete, coal ash and ore powder are dispersed in advance and the workability is compactly enhanced before raw materials are mixed and stirred in the production process. Furthermore, a tunnel kiln or box type structure is used for performing damp-heat curing and electromagnetic wave dehydration processes, instead of an original natural curing process, on a de-molded foam concrete blank, so as to quickly and continuously produce the foam concrete heat-insulating building material. The method has the advantages that the problems of a present method of manual workshops for producing the foam concrete, such as unstable quality, low production efficiency, big floor area of a production workshop, incapability of realizing standardized production, poor working condition, large investment of project construction and high cost of products are solved by the continuous production method for foam concrete, the continuous production method for foam concrete is importantly promoted and improved, the continuous and modernized production is realized, and the continuous production method for foam concrete is worthy of application and popularization.
