Abstract

Abstract

The corn husk fibers with different mass fraction and expanded polystyrene (EPS) particles were mixed and added to the cement matrix to study their effects on the density, water absorption, compressive strength, flexural strength, splitting tensile strength and frost resistance of the composites. The results showed that the higher the content of corn skin plant fiber, the lower the density and the higher the water absorption of EPS cement-based composites; the compressive strength decreases with the increase of fiber content and EPS content, and the maximum compressive strength is 2.2 MPa and the minimum is 0.8 MPa; the flexural strength increases first and then decreases with the increase of fiber content, and when the fiber content is 3%, EPS content is 1.3%, the maximum flexural strength is 1.2 MPa; the splitting tensile strength increases with the increase of fiber content and decreases with the increase of EPS content, and when the fiber content is 3%, EPS content is 1.1%, and the highest splitting tensile strength is 1.1 MPa. What’s more, the addition of corn bran fiber can effectively reduce the mass loss and strength loss of the composite and improve its frost resistance.
