Effect of Polyformaldehyde Fibers on Durability of Concrete
摘要
The influence of polyformaldehyde (POM) fiber on durability of concrete was discussed through experiments. The strength, pore structure, impermeability, chloride ion corrosion resistance and frost resistance of concrete specimens with 5 mix proportions were tested. The findings demonstrate that POM fiber can enhance concrete’s cube compressive strength and splitting tensile strength, reduce the average pore diameter, most integrable aperture, and porosity of concrete, and increase concrete’s compactness. As POM fiber improves the compactness of concrete, it can be used to increase the durability of concrete, including impermeability, sulfate corrosion resistance and frost resistance.
