Estimating the term…
An anti-bonding agent for blast furnace slag or its grading adjusted slag includes one or more polymers having a main constituent unit shown by 1 by a greater molar percentage than any other constituent unit where M is hydrogen atom, alkali metal such as sodium, alkali earth metal, ammonium or organic amine. Such an agent is used in an amount of 0.002-0.3 weight parts for 100 weight parts of such blast furnace slag or its grading adjusted slag, and may be applied as an aqueous solution with concentration of 1.5-10 weight %.
An anti-bonding agent for blast furnace slag or its grading adjusted slag, said anti-bonding agent comprising one or more polymers having a main constituent unit shown by Formula 1 given below by a greater molar percentage than any other constituent unit:
An anti-bonding method for blast furnace slag or its grading adjusted slag, said anti-bonding method comprising the step of using 0.002-0.3 weight parts of an anti-bonding agent for 100 weight parts of said blast furnace slag or grading adjusted slag thereof, said anti-bonding agent comprising one or more polymers having a main constituent unit shown by Formula 1 given below by a greater molar percentage than any other constituent unit:
