Title:
耐摩耗性コンクリート製品及びその製造方法
Document Type and Number:
Japanese Patent JP4620554
Kind Code:
B2
Abstract:

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/m3and a mortar amount of 550-375 L/m3is manufactured by the molding of the mixed and kneaded concrete of the mortar and the coarse aggregate and by curing under insulating, normal pressure steaming or warm water.
