Abstract
The physics experimentalresearch is carried out aiming at different contents of polypropylene fibers and steelfibers on impermeability ofhydraulicconcrete. Theresultsshowthattheimpermeabilityoftwo-typefibersconcretewasbetterthanordinaryconcreteinacertaindosage range. The improvement of polypropylene fibers on impermeability of hydraulic concrete is more notable. Adding 1 kg/m3 polypropylene fibers could achieve the best improving effect of impermeability of hydraulic concrete, after 24 hours of continuous pressure 1. 2 MPa the penetration height was of only 1. 1 cm, the relative permeability coefficient was 5. 62× 10-8 cm/h.关键词
