Nowadays, the reuse of waste is a challenge that every country in the world is facing in order to preserve the planet and introduce a circular economy. The chemical composition of some steel waste suggests that there are potentially appropriate substances for reuse, since this type of slag undergoes a process similar to that of cement in its manufacture. The advantages for the environment are obvious, as it valorises waste that is deposited in landfills. This paper studies the field of stainless steel, because its composition is different from that of carbon steel, and the replacement of cement with material or waste produced in the manufacture of stainless steel in a concrete matrix. This paper presents the results of replacing 25% of cement with material or waste produced in the manufacture of stainless steel in a concrete matrix whose values in the substitutions carried out were around 21% and 25% in terms of increased resistance capacity. These results have been obtained by carrying out tests, in terms of both strength and environmental capacity, allowing us to determine viable applications for the use of steel waste to improve the performance of cement or at least match it.
如今，为了保护地球并引入循环经济，废物再利用是世界上每个国家都面临的一项挑战。一些钢铁废料的化学成分表明，存在潜在适合再利用的物质，因为这种炉渣在制造过程中经历的过程与水泥类似。其对环境的益处显而易见，因为它使填埋的废物变得有价值。本文研究不锈钢领域，因为其成分与碳钢不同，以及在混凝土基体中用不锈钢制造过程中产生的材料或废料替代水泥的情况。本文展示了在混凝土基体中用不锈钢制造过程中产生的材料或废料替代25%水泥的结果，在所进行的替代中，就增强的抗压能力而言，其数值约为21%和25%。这些结果是通过在强度和环境容量方面进行测试获得的，使我们能够确定使用钢铁废料来改善水泥性能或至少使其相当的可行应用。
