According to the analysis sand-lime brick, autoclaved sand-lime brick walls and although can be used for basic industrial and civil buildings, but for the foundation and other building parts, the intensity must be above MU15 and MU15. Not be used for long-term heat above 200 ℃, construction sites and by the rapid thermal quench acidic media erosion. Autoclaved sand-lime brick or vapor barrier below the ground the following advantages of sand-lime brick masonry, the materials used in the lowest intensity level and the same as ordinary Brick. After autoclaved sand-lime brick out of the kettle temperature, humidity reduction and carbonization sand-lime brick specifications, in the course of the general trend is the volume shrinkage. Shrinkage variation is: the first three days of the vessel after the maximum contraction, average value of daily shrink 0.019mm / m; 3 ~ 30 Day Average daily shrinkage is 0.005mm / m; 30 days later the average daily value of contraction 0.003mm / m; in about 60 days, the average daily value of less than contraction 0.001mm / m, until it is stable. Use in different regions, due to temperature, humidity, sand-lime brick cement, sand-lime brick autoclaved same balance their different shrinkage values. At the same time after the temperature and humidity changes still have to change the volume. Compared with the sintered common brick, shrinkage of autoclaved lime-sand brick masonry is much greater. Further factors, variation is not the same, this special attention should be applied. Sand-lime brick specifications, Anhui, sand-lime brick, cement supplied by Wuhan Hongshan District of Wuhan pavilion cement operation.
