Ultrahigh-performance cement-based abrasion-resistant material
The invention relates to an ultrahigh-performance cement-based abrasion-resistant material, which has the features that the material can be used for performing surface coating on a newly built concrete structure or an old concrete structure damaged due to erosion and abrasion by means of optimizing the grain composition of multi-component cementing materials and the grain composition of aggregates and utilizing the chemical admixtures, such as a water reducing agent and the like, and the scour and wear resistance of a hydraulic structure is improved through the high scour and wear resistance of the material itself and the excellent bonding of concrete base materials. The technical advantages of the material include that scour and wear resistance of the material is significantly better than that of ordinary concrete; weather resistance and durability of the material are significantly better than those of organic scour and wear-resistant coating materials; a low water-binder ratio is obtained by means of optimizing the grain composition of the cementing materials and the grain composition of the aggregates, so that the requirements on construction mobility are satisfied; under the condition of standard maintenance, the material reaches the high strength of above 150 MPa during the concrete age of 28 days; the impervious performance, carbonation resistance, chloride-ion penetration resistance as well as freezing-thawing cycle resistance and the like of the material are better than those of the ordinary concrete.
