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. Cement hydration reaction more fully sand-lime brick, it has a stable strength and performance. In the atmosphere of the reactor, there is more growth in the early strength, will no longer increase, remain stable. In wet conditions and long-term immersion in water gravity sand-lime brick, strength will be enhanced. ⑤ temperature resistance: autoclaved sand-lime brick is not heated above 200 ℃ long sand-lime brick Beijing, it had no effect below 200 ℃ sand-lime brick, strength. ⑥ Chemical resistance: MU15 than sand-lime brick strength soaked little change in acid solution. According to the characteristics of the production process, the brick into sintered products with non-sintered product categories. Depending on the material used, the brick into clay brick, shale brick, coal gangue brick, fly ash brick, slag bricks, sand-lime brick. According to the shape, brick can be divided into solid brick, porous brick, porous brick and hollow brick. Common bricks and shaped bricks. FIG sand-lime brick, cement Wuhan (certified), Sichuan sand-lime brick by Hongshan District of Wuhan pavilion cement operation. Hongshan District of Wuhan pavilion cement business unit (www.whltsn.com) (www.hbltsn.com) was Wuhan, cement and products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Wuhan cement leadership with the staff warmly welcome all inquiries negotiations to create a better future Wuhan cement.
