  • RESEARCH ON WORKABILITY IMPROVEMENT EFFECT AND STRENGTH OF SPRAYED CONCRETE BY TYPE-1 FLY ASH

説明

For effective use of coal ashes generated from coal-fired power plants, the research which aims at improvement of environment in spray work by decreasing dust has been done by using type-1 fly ash as admixture of sprayed concrete. As a result, the use of type-1 fly ash in place of fine aggregate confirmed that the water content of base concrete is decreased, and that the resistance against material segregation of base concrete is improved. From the result of the spray tests executed at the model tunnel and the actual road tunnel, the use of standard 100kg/m3 type-1 fly ash in place of fine aggregate confirmed that the excellent work is made by decreasing the amount of dust and rebound during spraying, and that the strength development of sprayed concrete improves excellently from the initial ages over the long ages.
