Browning method for slag civil engineering materials and construction method for simple pavement

摘要

PROBLEM TO BE SOLVED: To increase strength when used as a civil engineering material, and provide a low-cost pavement method in the case where a slag-based civil engineering material getting browned is applied to a low-cost pavement.SOLUTION: In a browning method for a slag-based civil engineering material, a polyferric sulfate solution at a concentration of 5-40 mass% with respect to the whole solution is sprayed by 2-6 L/mon a surface of the slag-based civil engineering material. The total concentration of the slag-based civil engineering material amounts to 100 mass% by containing 70 mass% or more of steel slag and 15 mass% or more of granulated blast furnace slag.SELECTED DRAWING: Figure 2
