Generation of fly ash bricks drying shrinkage , drying shrinkage value is the number of standard

Fly ash brick making machine products will result in greater loss of water due to drying shrinkage deformation, resulting in wall cracks , affect housing and normal use. In order to control this type of housing cracking, a large number of researchers focus on the domestic bricks from improved production technology, raw materials and mix to reduce drying shrinkage of brick , from the perspective of improving the material properties to control the drying shrinkage cracks in the wall .
However, only in the use of the environment to achieve equilibrium moisture content , the drying shrinkage of bricks that the use phase of the drying shrinkage will lead to housing cracking. Masonry relative humidity, the greater the environment , the greater the equilibrium moisture content of masonry , masonry drying shrinkage using the smaller stage , which is manual clay brick making machine , etc. The drying shrinkage of concrete masonry experimental results . mobile brick making machine manufacturers that brick wall on the moisture content of greater wall drying shrinkage greater . However, these studies can not be established for a certain kind of material drying shrinkage estimation formula.
Drying shrinkage of masonry brick and mortar by the combination of drying shrinkage , and some criteria that: Brick masonry in a large proportion of the volume occupied , drying shrinkage of masonry bricks directly from the drying shrinkage rate to determine . Thus, the use phase of fly ash bricks drying shrinkage cracks on the structural control is beneficial. People in this concrete structure in terms of a number of studies , and few studies on the brickwork .
