Measures aerated brick equipment products to prevent a leakage crack minimize actual shrinkage of value (1) do not use age of less than 30 days of wall materials wall materials and other products, to ensure that the new wall materials prior to use with the more basic The actual shrinkage of small value and high strength. Block drying shrinkage of autoclaved aerated concrete block should ≤0.5mm / m, for exterior of autoclaved aerated concrete block compressive strength of not less than 5Mpa, for the interior of the compressive strength of not less than 3.5 Mpa. (2) should strictly control the moisture content of the new wall materials and water depth. When in use, should be 1 to 2 days in advance watering moist, not with the water with puzzle. Rain during construction, new wall materials should not be affixed to the open dumps, and should be a reliable anti-rain measures. The new wall materials from rain shall immediately masonry. (3) the preparation of lime plaster mortar must be used with a pore size greater than 3mm × 3mm mesh filter, and make it fully matured. Mortar should be accompanied by mechanical agitation and with the guarantee stirring time is not too short and not too long time, prohibited the use of gray overnight. 2, so that most of the heavy masonry shrinkage deformation occurs in the top of the wall and plaster pressure before (1) Japanese puzzle height of not more than 1.4m, for autoclaved aerated concrete block, because weight is too light, easy to create and mortar inadequate cementing cracks, so when you stop puzzle, a leather top with a leather floating brick brick top pressure, and then the next day to continue to remove it when the masonry. Wall plugs should be in the top seven days, and 60 ° angle to the top tight. Plaster also be seven days. (2) should take effective measures to control gray seam thickness and fullness. Appropriate to the "Three Ones" brick masonry wall method. When using masonry shop slurry method, should be limited to the length of paved pulp. www.zzzhuoli.com copper processing equipment www.zhuoli168.com autoclaved aerated concrete equipment, aerated concrete block equipment www.zhuoli888.com aerated block device aerated block cutting machine www.zhuoli668.com uncoiler www.zljxgs .com aerated concrete equipment www.zhuoli666.com aerated brick equipment
