This paper focuses on research concerning the ecotoxicological properties of granulated slag from the pilot production of gray iron with red mud addition and concrete composites with the application of this slag. Red mud is a hazardous waste generated in the production of aluminium oxide. Negative ecotoxicological tests are, therefore, one of the basic prerequisites for the ability to use granulated slag from gray iron pilot production. Granulated slag and concrete composite samples with various ratios of granulated slag have been subject to ecotoxicity tests: determining root growth inhibition in the highly-cultivated plant , and determining acute toxicity in . The results of ecotoxicological testing of granulated slag from gray iron standard production and gray iron pilot production with the additive were, according to the standard (STN 83 8303), negative. Additionally, the results of ecotoxicological tests of concrete composites were negative, with the exception of a 50% substitution of fine aggregate with slag from gray iron pilot production.
本文重点研究了添加赤泥的灰口铁中试生产的粒化炉渣以及应用该炉渣的混凝土复合材料的生态毒理学特性。赤泥是氧化铝生产过程中产生的危险废物。因此，阴性的生态毒理学测试是使用灰口铁中试生产的粒化炉渣的基本前提之一。对具有不同粒化炉渣比例的粒化炉渣和混凝土复合材料样品进行了生态毒性测试：测定高度栽培植物的根生长抑制情况，以及测定……中的急性毒性。根据标准（STN 83 8303），灰口铁标准生产的粒化炉渣以及添加添加剂的灰口铁中试生产的粒化炉渣的生态毒理学测试结果为阴性。此外，混凝土复合材料的生态毒理学测试结果也为阴性，但用灰口铁中试生产的炉渣替代50%细骨料的情况除外。
