A kind of non-steaming foam concrete, block production method and special cutting equipment

Abstract

The invention discloses steaming-free foam concrete, a production method of steaming-free foam concrete building blocks and dedicated cutting equipment. The steaming-free foam concrete comprises, by weight, 150 parts to 400 parts of cement, 20 parts to 200 parts of mixed materials, 50 parts to 300 parts of water, 15 parts to 50 parts of regulators and five parts to 15 parts of foaming agents. The strength of the building blocks can be improved fast and is large, and above all, the heat preservation, heat insulation and water prevention performance is good, investment cost is low, production efficiency is high, and cutting efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of pumping chemical foaming foam concrete, production technology and special cutting equipment, and in particular relates to a non-steaming foam concrete, a block production method and special cutting equipment. Background technique [0002] At present, foamed concrete is a widely used lightweight thermal insulation material. It has light weight, good thermal insulation performance and low price, and has become the leading product of environmental protection and energy-saving materials. Promoting the use of this new type of building material can not only improve building functions, improve construction quality and construction efficiency, meet the needs of modernization and functionalization of the construction industry, but also effectively utilize existing industrial waste resources and improve resource utilization. [0003] At present, the commonly used materials in the market are aerated blocks, and buil...

Problems solved by technology

The production line adopted is to produce blocks with foam concrete cast-in-place equipment, which has the following problems: 1. The mold investment is very large, which wastes a lot of money

2. The size of the mold is fixed, which cannot meet the different size requirements of customers. If the size of the block is changed, a large number of new molds need to be invested, and the original mold is lost, which wastes resources. A large number of molds and a waste of space

3. The traditional cast-in-place equipment adopts the method of timely mixing foam and timely pumping, while the raw materials of blocks include cement, water, sand, coal ash, water reducing agent, foam and other materials, and the density of these materials varies greatly , if cement mortar and foam are mixed in time, the product will be uneven and the quality of the product will be poor

4. Since the cast-in-place process is greatly limited by the equipment, if the equipment changes slightly, the product will have a big difference, and the product performance cannot be guaranteed

Although the foam concrete cast-in-place equipment has the advantages of fast construction speed and convenient movement, it is very unreasonable for block production

[0006] The invention patent with the application number 201210125875.5 published on September 12, 2012 discloses a cast-in-place foam concrete and its manufacturing method. The slurry is composed of cement, water, cement foaming agent and admixture. The raw material is cement products, and the internal It is full of closed pore structure, has good affinity with building structure, high strength, durable fire protection, and extensive resources. It is not easy to be uniform, the size of the internal pores is different, the structure is chaotic, and the foaming agent is an organic material, which is not beneficial to the condensation of the cement slurry, resulting in slow condensation, delayed cement hydration, and prone to collapse after pouring.

Its application number is 201010101103.9. The invention patent of polystyrene particle foamed cement composite material mixing and conveying device has the defects of low production mixing efficiency and no automatic control of production.
