After autoclaved sand-lime brick out of the kettle temperature, humidity reduction and carbonization, in the course of the general trend is the volume shrinkage. Shrinkage variation is: the first three days after the vessel contraction maximum Wuhan sand-lime brick prices, the average shrinkage is 0.019mm / m per day; 3 to 30 days the average daily value of contraction 0.005mm / m; 30 days later on average daily shrinkage is 0.003mm / m; approximately 60 days Wuhan sand-lime brick model, the average daily value of less than contraction 0.001mm / m, until stable. Use in different regions, due to temperature, humidity Wuhan sand-lime brick, 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 influencing factors are not the same variation of the advantages of Wuhan sand-lime brick, this special attention should be applied. Standard brick specifications for 240mm × 115mm × 53mm, including 10mm thick mortar joint, the length generous ratio of 4: 2: 1. Standard brick wall brick building when the width of the multiple (115mm + 10mm = 125mm) modulo "coordinate building modulus of uniform standards" and China's current number of uncoordinated M = 100mm fundamental mode, which is due to the brick size determine the time earlier than modular coordination to determine the time.
