Influence of the Polymer Modified Mortar Coating on Gas Permeability of Steel Fiber Concrete

Article Preview

Abstract:

The gas permeability of polymer modified mortar coating add steel fiber concrete compound structure was studied by thickness-wall cylinder structure experiment. The coatings were characterized by scanning electron microscope,energy-dispersive X-ray spectroscopy.the gas permeability of steel fiber concrete is 6.85×10-15 m2. applying the coating can reach 10-17 m2. The intrinsic gas permeability of polymer modified cement based materials is 1.36×10-17 m2 using regression calculate analysis method .Coating thickness is constant, raw materials composition and structure is the fundamental factors affecting permeability.
