① durability frost resistance: refers to the ability to resist repeated freezing and thawing brick effect. Autoclaved sand-lime brick production if required to meet product standards sand-lime brick, can withstand frost resistance test specifications sand-lime brick, autoclaved sand-lime brick frost resistance to its own strength the cement sand-lime brick, high strength by frost resistance. ② Water resistance: after effects include dry and wet cycles and changes in their strength when long-term immersion in water, the wet-dry cycle effects or long-term water autoclaved sand-lime brick compressive strength are on the rise. Brick is the most traditional masonry materials. By clay as the main raw material gradually to use coal gangue and fly ash and other industrial waste sand-lime brick proportion of development, while the solid to the porous, hollow development by sintering the non-sintered development. According to the building project in the use of different parts of the puzzle into brick wall, floor tile, brick arch shell, floor tiles, bricks and chimney brick sewer. Sintering brick wall divided according to different load-bearing brick building performance, non-load-bearing brick, engineering bricks, insulation tiles, acoustical tiles, decorative brick, tile and other flowers. Sand-lime brick, cement Wuhan (certified), Ningxia 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.
