Waterproof coiled material is mainly used for building wall, roof, and tunnels, highways, the place such as landfill, resist the outside rain, groundwater seepage of a flexible roll into flexible building materials products, as a foundation for engineering and no leakage connection between buildings, is the first barrier of the engineering of waterproof, plays an vital role in the whole project.
more +Mechanical properties:(1) Performance index: the inspection items to examine the mechanical properties of rebar include tensile test (tensile strength, yield strength, elongation), bending test (primary bending and reverse bending).
more +1. Hollow brick: by clay coal gangue or fly ash as the main material, the hole is larger, the hole rate is greater than 35% of the sintered hollow brick, used for retaining structure.2. Block: concrete hollow block, aerated concrete block, silicate solid block.
