The existence of sloping roof also played a role in the isolation room below, it is possible not to take other measures under conditions in which the room below insulation. Since the roof sloping roof design and construction can be varied and colorful, Wuhan cement tile, so beautiful houses, Wuhan cement board, more personalized, and the city beautiful, and many of the old flat on the top floor have also been flat to pitched transformation , sloping roof system has become the mainstream of Chinese residential buildings. Due to the small internal voids, water is not easy to penetrate. Small plants generally use parallel extrusion equipment manufacturers, artificial spices or general DIY mixers, only added to the water-cement ratio of 0.6 to 0.7 to the slurry Ban Cheng, Wuhan cement pipes, coupled with the metal mold, can not withstand high pressure, just wiped away overnight, Wuhan cement, thus greatly reducing the density of the internal voids both big and great, so impermeability poor. In even on cloudy days, rain will seep under the back of the tile drop, and then penetrate the roof. (According to the data, when the water-cement ratio of cement added to 0.7 from 0.4, impermeability decreased 100 times !!) the density of the end, not only the strength and impermeability of poor fall, good flexural strength of up to 300 watts kg, Chavalit less than 100 kg. Poor impermeability winter intolerance to cold. Especially in the north, snow seep tile in the day, at night icing expansion, the watt Splitting gradually peeling destruction, the life of the tile will not be long. Wuhan cement board | pavilion cement (Online) | cement provided by Wuhan Hongshan District of Wuhan pavilion cement operation.
