Production process of pouring foam concrete into hollow brick

Abstract

The invention belongs to the technical field of preparation of self-insulating building blocks, in particular to a production process of pouring a foam concrete into hollow brick. The adopted scheme is as follows: a special structure formed by burr crushed shells and hollow beads is added into a conventional foam concrete insulating material to enhance the compressive strength and the insulating effect, so that the strength of the brick body and the combining firmness of the brick body and the pouring material are ensured while the brick is insulating and energy-saving. Use of a foaming agentcan be reduced to improve the economical benefit. The problem that the later strength is decreased and the alkalinity is too high caused by an accelerator is solved while efficient production is met.

Description

technical field [0001] The invention belongs to the technical field of self-insulation block preparation, and in particular relates to a production process for pouring foam concrete into hollow bricks. Background technique [0002] Hollow bricks have the advantages of light weight, easy construction, and saving raw materials. As a new type of building material, foam concrete has the effect of noise reduction and heat insulation. Based on the market demand and social needs of heat preservation and energy saving, construction industry technicians combine the two , pouring foam concrete into hollow bricks, self-insulating blocks came into being, and received widespread attention and a large number of applications. [0003] However, in the prior art, hollow bricks filled with ordinary foamed concrete still have many deficiencies, such as poor bonding between foamed concrete and bricks, difficulty in balancing thermal insulation performance and brick strength, and easy collapse o...

Problems solved by technology

[0003] However, in the prior art, hollow bricks filled with ordinary foamed concrete still have many deficiencies, such as poor bonding between foamed concrete and bricks, difficulty in balancing thermal insulation performance and brick strength, and easy collapse of foamed concrete, etc. The foaming effect in actual use is not ideal. In addition, because bricks need to be produced in large quantities, in order to meet market demand, quick-setting agents are usually added to concrete to speed up the production rhythm, but it also brings low strength and excessive alkalinity in the later stage. high problem
