| Abstract: | Non-fired and non-steamed bricks were prepared by using the iron ore tailings in Anshan-Benxi Area as raw material.In the preparing process,a certain amount of grit and cement was mixed as additives.The brick was formed by pressing process and was cured under natural condition after demould.The size of the brick is 240×115×53mm.Strength test results showed that the compressive property and the frost-resisting strength reached standards of MU10.The dosage of the iron ore tailings in the feed proportioning has approached 60%,the comprehensive reuse rate of the iron ore tailings is higher. |
