To provide a wear-resistant concrete product where the wear-resistance of concrete is enhanced to be more than equivalence to the compressive strength of concrete and its manufacturing method.
The wear-resistant concrete product is the mixture of mortar and coarse aggregate. A binding material in the mortar consists of cement, silica fume of 2-15 pts.mass and fly ash classified to 20 μm or less of 0.5-10 pts.mass to 100 pts.mass of cement. A water rate to the binding material is regulated to 40 mass% or less by using a high performance water reducer or a high performance AE water reducer. The wear-resistant concrete product having a unit coarse aggregate amount of 450-625 L/m
