③ water absorption: Compared with the sintered common brick, water absorption rate and Bricks close. ④ intensity under natural conditions: sand-lime brick autoclaved at high temperatures, the formation of the reaction autoclave. Hydration relatively full sand-lime brick equipment, thus having stable strength and performance. In the atmosphere of the autoclave sand-lime brick, pre-intensity have more growth, will no longer increase, 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. According to GB50003-2001 "masonry structures design" can be seen, the design value of the compressive strength of autoclaved lime sand brick and sintered common brick compressive strength design values ??are the same, the difference is autoclaved sand-lime brick intensity level does not C30; when the span of not less than 7.5m of sand-lime brick masonry under the beam adjustment factor of 0.9, which is the difference between the proportion of sand-lime brick and sintered common brick, construction quality control level to level B, GB50003-2001 given steam pressure sand-lime brick design value of shear strength and shear strength of sintered common brick design value, it is easy to see the shear strength of autoclaved sand-lime brick is 0.7 times the sintered common brick.
