高钛高炉渣碎石用做砼骨料的研究

A RESEARCH ON HIGH-Ti BLAST FURNACE SLAG CRUSHED STONE APPLIED FOR CONCRETE AGGREGATE

攀钢高炉渣TiO2 含量 15 %以上 ,与普通高炉渣的组成结构有较大差异 ,高钛高炉渣的性质研究及其用于砼的试验说明 :高钛高炉渣结构稳定 ,其碎石用做砼骨料与普通碎石相比 ,抗压强度及劈拉强度稍高于后者。此外 ,其运用实例也说明了高钛高炉渣砼的稳定性。开发利用高钛高炉渣对环境保护 。

Structure of blast furnace slag with 15% TiO 2 at Pangang is different from the normal blast furnace slag.Based on experiments on the property of Ti-bearing slag and its application in the concrete,it is concluded that the structure of high-Ti blast furnace slag is stable and compressive strength and breakage strength are higher than the latter, as compared with normal crushed stone used for concrete aggregate.Otherwise,the stability of it had been proved by the example of application.Development and utilization of the blast furnace slag are very important for the environmental protection and increasing slag yard lifetime at Pangang.
