摘要
Abstract
Based on the analysis of the properties of iron tailings and the existing mature technology,condition test wsas conducted on the different ratio by using tailings of Qian'an iron ore concentration plant as the main raw material and adding lime,retarding agent,regulator.When the ratio of water:solid was 0.09,the ratio of iron tailings:lime:retarding agent:regulator was 80 ∶ 8 ∶ 3 ∶ 9,forming pressure was 25 MPa,steam pressure was 1.3 MPa,rising temperature was 150 min,constant temperature was 360min and cooling temperature was 120 min,autoclaved sandlime brick with average compressive strength of 26.4 MPa and average flexural strength of 5.3 MPa was made,whose technology index was up to the requirements of MU25 in nation standard GB 11945-2006" autoclaved sandlime brick".The comprehensive utilization of iron tailings was realized and enterprise economic benefit and social benefit were increased.关键词
