摘要

本文揭示了用水泥固定技术处理炼钢厂有害放射性电弧炉粉尘的适宜成分。在EAFD替代量为0%、15%、25%、35%、40%、45%和50%的情况下,将自来水与粘结剂(即普通硅酸盐水泥:OPC和EAFD)混合制备水泥试件。水胶比固定为0.40。在14天和28天的养护时间下,对制备的试样进行了抗压强度试验。结果表明,当EAFD加载量为25%时,试样的抗压强度最高。然而,对于水泥废料形式的抗压强度标准,使用较高EAFD载荷的成分(35% EAFD, 28天养护时间)进行固定是有利的,并且符合标准。采用x射线衍射(XRD)、x射线荧光(XRF)和扫描电子显微镜(SEM-EDS)分析了样品的相组成和微观结构。

Cement Immobilization of Hazardous and Radioactive Electric Arc Furnace Dust
This paper reveals an appropriate ingredient to operating the hazardous and radioactive electric arc furnace dust (EAFD) from the steel production factory using the cement immobilization technique. The cement specimens were prepared by mixing tap water with the binders (i.e., ordinary Portland cement: OPC, and the EAFD) at the different EAFD replacement of 0%, 15%, 25%, 35%, 40%, 45%, and 50% by weight. The water-to-binders ratio was fi xed at 0.40. The compressive strength test on the fabricated samples was performed at two different curing times of 14 and 28 days. It was found that the highest compressive strength of the samples can be obtained when the EAFD loading was 25%. However, the compressive strength criteria for the cement waste form, the use of the ingredient with the higher EAFD loading (35% EAFD with 28-day curing time) for the immobilization is favorable while meets the criteria. The phase composition and microstructure morphology of all samples were analyzed by X-ray diffraction (XRD), X-ray fl uorescence (XRF) and scanning electron microscopy (SEM-EDS).

期刊介绍: The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
