Air-entrained blocks
In cold areas, energy saving and heat preservation of buildings have always been the focus of winter life. The emergence of air-entrained blocks is a manifestation of the progress in the field of building materials under the requirements of the new social background. As air-entrained blocks follow the my country's construction industry has attached unprecedented importance to the concept of environmental protection and has been widely promoted. Traditional materials have gradually disappeared in the market in the new era due to high pollution and large consumption of land resources. This has laid the background for the rise of aerated blocks, allowing them to gradually become It has become a new force in wall materials among building materials.
Air-entrained blocks are now used in more and more applications, and their application range is also very wide. Almost all buildings use air-entrained blocks. The compressive strength of this kind of soil after hardening is very high.
The most important mechanical property of the air-entrained block after hardening refers to the ability of the air-entrained block to resist stresses such as compression, tension, bending, and shear. Water-cement ratio, cement type and amount, aggregate type and amount, and mixing, molding and curing, all directly affect the strength of aerated blocks.
According to the standard compressive strength of the air-entrained block, a cube with side length is used as the standard test piece. After curing for days under standard curing conditions, the strength grade is divided into cube compressive strength with a guaranteed rate measured according to the standard test method. , called label, divided into equal parts. The tensile strength of an air-entrained block is only // of its compressive strength. Improving the ratio of tensile to compressive strength of air-entrained blocks is an important aspect of modification of air-entrained blocks.
The maintenance structure composed of aerated blocks is a heavy-duty maintenance structure. With the popularity of new wall building materials in China and the gradual increase in fly ash autoclaved brick factories, the price of aerated blocks is gradually becoming more popular.
