Problems solved by technology

However, due to the difficulty in controlling the degree of resting of the block bricks, the softness and hardness of the block bricks are difficult to control, so that the block bricks may collapse during the cutting process, causing the block bricks to be difficult to form. Therefore, there are still room for improvement

Abstract

The invention relates to the field of building materials, and provides an aerated concrete building block brick specific to the problem that the building block brick is difficult to cut and form. Theaerated concrete building block brick is prepared from the following ingredients in parts by mass: 45-60 parts of water, 25.5-34 parts of medium sand, 25.5-34 parts of gypsum, 21-28 parts of cement, 22.5-30 parts of lime, 2.1-2.8 parts of fish gelatin powder and 7.5-10 parts of hollow glass beads. By adding the fish gelatin powder, the fish gelatin powder has good affinity and water-retaining property, can form a skin membrane and is conducive to forming a protective film on the outer surface of the concrete building block brick, meanwhile, the thickness of concrete is increased, the concretebuilding block brick is conducive to forming a gelatinization shape in the recuperation process and takes on a jelly-like state in the cutting process, therefore, the elasticity and strength of the concrete building block is conducive to being improved, and the concrete building block is difficult to collapse in the cutting process and convenient to cut and form.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, it relates to an aerated concrete block brick. Background technique [0002] Air-entrained concrete block brick is a new type of building material that is lightweight, porous, thermally insulated, good in fire resistance, nailable, sawable, planable, and has a certain degree of earthquake resistance. [0003] Aerated concrete block bricks are generally bricks with a certain strength formed by crushing, ball milling, measuring, pulping, mixing, pouring, resting, cutting, and steaming at high temperature and high pressure. However, due to the difficulty in controlling the degree of resting of the block bricks, the softness and hardness of the block bricks are difficult to control, so that the block bricks may collapse during the cutting process, causing the block bricks to be difficult to form. Therefore, there are still room for improvement. Contents of the invention [000...
