高炉水淬渣的利用研究
The Research on Utilization of BlastFurnace Water Quenching Residue
【摘要】 对邯钢高炉水淬渣的可磨性 ,水淬渣不同细度不同添加量的水泥胶砂强度、混凝土强度进行了试验研究。结果表明 ,随着水淬渣细度的提高胶砂强度值增大 ,随着水淬渣添加量的增大胶砂强度值减小。当水淬渣细度为 - 0 .0 74 mm占 98.0 %以上 ,其添加量超过 30 %时 ,仍能超过GB175 - 1999- 42 .5水泥的胶砂强度值。掺磨细水淬渣粉可以配制 C4 0以上的混凝土 ,在相同掺量下 ,随着水淬渣细度的增加 ,混凝土各个龄期的强度增加 ;在相同细度下 ,随着水淬渣粉掺量的增加 ,混凝土的早期强度明显降低 ,但后期强度增长很快 ,2 8d后可超过不掺渣粉的混凝土强度 ,水淬渣在 C4 0混凝土中的添加量可以达到 35 %以上。
【Abstract】 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.
