摘要： PROBLEM TO BE SOLVED: To provide an expansion stability evaluation technology of a solidified body (1) capable of evaluating expansion stability in the solidified body having the same composition as the case at an ordinary temperature, (2) exerting no adverse effect to a work environment at the expansion stability evaluation time without generating hydrogen sulfide even in the case of a solidified body including blast furnace slag, and (3) capable of evaluating the solidified body expansion stability during an optional period at an optional temperature, by evaluating the expansion stability of the solidified body at 100°C or below. SOLUTION: This expansion stability discrimination method of the solidified body including steel slag is characterized by discriminating stability during a desired period at a desired temperature by confirming existence of breakage of the solidified body after curing the solidified body comprising the steel slag or the solidified body including the steel slag during a prescribed period at a prescribed temperature of warm water below 100°C which is a condition estimated as an approximately equivalent load as the desired period at the desired temperature.

摘要： PROBLEM TO BE SOLVED: To evaluate accurately stability of steel slag subjected to aging treatment such as a blast furnace, converter or electric furnace slag generated in an iron mill or the like. SOLUTION: In this slag stability evaluation method, the slag subjected to the aging treatment is sieved by a first sieve mesh, and the value determined, when the particles of minus sieve in the above sieving are sieved again by a second sieve mesh smaller than the first sieve mesh, by (the slag mass of the minus sieve of the second sieve mesh)/(the slag mass after the aging treatment before classification)×100% is used as 'the fine grain portion ratio (%) of the slag after the aging treatment'. Then, the slag subjected to the aging treatment is further subjected to hydration acceleration treatment, dried and sieved by the first sieve mesh, and the particles of minus sieve are sieved again by the second sieve mesh, and the value determined by (the slag mass of the minus sieve of the second sieve mesh after the hydration acceleration treatment)/(the slag mass before the hydration acceleration treatment)×100% is used as 'the fine grain portion ratio (%) of the slag after the hydration acceleration treatment'. The value determined by subtracting 'the fine grain portion ratio of the aging slag' from 'the fine grain portion ratio of the slag after the hydration acceleration treatment' is used as the slag decay rate.
