Advantages of cement mortar lining anti-corrosion pipe

As the cement mortar lining anti-corrosion steel raw cement mortar use is great, in construction, foundation and masonry wall can be used to make adhesives massive masonry materials, such as rubble, red brick use cement mortar; the second is used for interior and exterior plastering. Cement mortar when in use, but also often incorporated additives such as micro-foam agents, water powder to improve its workability and viscosity. Cement mortar in proportion to join the stones, they become concrete.

The biggest advantage of the cement mortar lining of steel corrosion, since the concrete inside the steel pipe, it is possible to absorb large amounts of heat, so the temperature of the cross section of the steel pipe when subjected to uneven distribution of the fire, increasing the fire resistance of steel, slowing the rate of temperature rise of steel, and once the pipe yield, also be able to withstand most of the dirt load, to prevent structural collapse. The experiment proved refractory three hours to achieve the level of savings compared to the requirements of fire and steel pipe coating 1/3 a 2/3 or even more, as the pipe diameter increases, the more savings paint.

After the cement mortar lining of steel corrosion completion of the last step is particularly important, it is dried, refers to the dried 2-3 days in a natural state, is mainly to prevent the shipment of the process due to the turbulence leads to cracks in the cement mortar.
