Problems solved by technology

[0004] However, the existing air-entrained concrete blocks all use the method of adding gas-generating materials to the raw materials. Although gas can be released and small and uniform pores can be formed to make the air-entrained concrete have a porous structure, it will undoubtedly reduce the cost of the concrete block. Poor structural strength, prone to damage or risk of reduced life, limiting its application in high-strength fields

Abstract

The invention discloses a lightweight concrete block for environment-friendly construction and a preparation method of the lightweight concrete block. The invention belongs to the technical field of buildings. According to the invention, an innovative mode of throwing the spontaneous gas inner vibrating ball can be realized, based on the magnetic repulsion effect, the magnetic particles are autonomously and uniformly distributed in the slurry, then, the gas generation action is triggered under the heating action, the built-in gas-forming powder begins to be heated and decomposed to release gas, the natural gas is released into the slurry along a gas-forming outer hopper on the natural gas-forming inner vibrating ball, fine and uniform air holes are formed, the concrete building block has aporous structure, the traditional gas generating material is replaced, meanwhile, when the spontaneous gas inner vibrating ball releases gas, high frequency vibration is formed in the slurry so thatthe fluidity and uniformity of the slurry are improved, thus indirectly improving the strength of the block. According to the self-aerated concrete block, the self-aerated inner vibration ball is arranged in the slurry, high-frequency vibration is formed in the slurry, the fluidity and uniformity of the slurry are improved, the strength of the block is indirectly improved, the self-aerated inner vibration ball and the block can form a tight whole, the strength of the block is further improved, a large pore channel is reinforced, and a block forming process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction, and more specifically relates to a lightweight concrete block for environment-friendly construction and a preparation method thereof. Background technique [0002] Air-entrained concrete block is a new type of building material that is lightweight, porous, thermal insulation, good fire resistance, nailable, sawable, planable, and has certain earthquake resistance. As early as the early 1930s, China began to produce this product, and it was widely used in high-rise frame structure buildings. It is an excellent new building material and has the advantages of environmental protection. [0003] The general quality of aerated concrete blocks is 500-700 kg / m3, which is only equivalent to 1 / 4-1 / 3 of clay bricks and lime-sand bricks, and 1 / 5 of ordinary concrete. It is a lighter type of concrete. It is suitable for filling walls of high-rise buildings and load-bearing walls of low-rise buildings. ...
