Use in different regions, due to temperature, humidity, 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. Also influencing factors, light brick wall, variation is not the same, this special attention should be applied. Autoclaved sand-lime brick main raw material for the sand, light brick price, promotion autoclaved replace sand-lime brick brick reducing environmental pollution, protect farmland, improve building function has a positive effect. Autoclaved lime sand brick for performance analysis, research, application of autoclaved sand-lime brick discuss the existing problems, light brick press, and proposed construction design and technical measures to be taken. Autoclaved sand-lime brick is sand, lime as the main raw material, light brick, the stock preparation, compression molding, autoclave curing made of bricks, sand-lime brick short, the test results show, autoclaved lime-sand brick, both It has good durability, but also has a high wall strength.
