To provide the production of lining concrete, by which sufficient initial strength of the lining concrete can be obtained even at the time of adding a small amount of a quick setting agent and also, the expression of long-term strength of the concrete is hardly inhibited, and to attain effective utilization of resources through the effective utilization of eco-cement using waste as a raw material.
This lining concrete is used for a concrete lining method that comprises adding a quick setting agent to concrete mixed beforehand and subjecting a surface to be worked to lining work with the resulting lining concrete. In the production of the lining concrete, as the concrete mixed beforehand, a hydraulic composition consisting of gypsum and a fired material which is obtained by using as a raw material, at least one of municipal solid waste incineration ash and sewage sludge incineration ash and contains 10 to 40 wt.% of at least one of (CaO)11(Al2O3)7.CaCl2, and (CaO)3.Al2O3, and also contains at least one of (CaO)2.SiO2 and (CaO)3.SiO2, is used.
