④ intensity under natural conditions: sand-lime brick autoclaved at high temperatures, the formation of the reaction autoclave. Hydration reaction more fully, it has a stable strength and performance. In the atmosphere of the reactor, there is more growth in the early strength, Branch-light brick, it will no longer increase, Branch-light brick prices remain stable. In wet conditions and long-term immersion in water, the intensity will increase. ⑤ temperature resistance: autoclaved sand-lime brick is not prolonged exposure to heat above 200 ℃, less 200 ℃, basically no effect on strength. ⑥ Chemical resistance: MU15 than sand-lime brick strength soaked little change in acid solution. Aerated concrete block wall at the corner of the wall should be vertical and horizontal puzzle blocks overlap each other, separated from the end face of skin exposed brick. Aerated concrete block wall of the T-junction, light brick Branch-how, should make the cross-block partition wall skin exposed face, and sat at a vertical wall blocks. Former aerated concrete block masonry, brick Keyu Light, should be based on the plane of the building, elevation drawing block arrangement diagram. Set the number of rods in the wall skin around the corner, the number of pole leather skin to draw several blocks and blocks height, and on the opposite sideline pull alignment between the block, according to the alignment of masonry.
