The
grinding characteristics of water
quenching residue of Handan Iron and Steel Limited Company were experimented.At the same time,the cement micelle and
concrete strengths were tested in adding different amount of water quenching residue with various
particle size.The results indicated that the cement micelle strength
increased with the decrease of the particle size and decreased with the increase of the amount of water quenching residue.In the condition that the water quenching residue whose particle size was smaller than 0.074mm surpassed 98
percent and the quantities of the residue surpassed 30 percent,the value of cement micelle strength still could exceed the standard of GB175-1999-42.5.The water quenching residue powder may make up C40 concrete.Adding equal amount of water quenching residue to the concrete,the strength in different periods increased as the particle size of the water quenching residue decreased.While increasing of water quenching residue with the same particle size,the strength of concrete in early period decreased obviously and that in the late period increased rapidly.The strength value of 28 days′ concrete in the presence of water quenching residue powder is bigger than that without water quenching residue powder.The addition of water quenching residue to the C40 concrete may surpass 35 percent.
