- Abstract
Featured Application: Steel slag self-compacting concrete (SSCC) with relatively ideal workability was prepared by substituting steel slag for natural fine aggregate to realize solid waste resource utilization. It is beneficial to solve the problems of steel slag abandonment, land occupation, environment pollution and low utilization rate, and realize utilization of a large amount with low-energy consumption for traditional material saving and sustainable development. SSCC has very high application value and economic significance. There is important application value and economic value in exploring the potential use of steel slag to prepare self-compacting concrete (SCC) and make full use of solid waste resources. In this paper, steel slag self-compacting concrete (SSCC) with relatively ideal workability is prepared by using steel slag instead of natural fine aggregate based on mix proportion optimization and SSCC performance research. The filling ability, passing ability and resistance segregation were tested to evaluate the workability of SSCC. The results show that when the content of steel slag sand is 20%, the workability performance of SSCC is similar to that of SCC with natural aggregates. When the content of steel slag sand is less than 60%, the performance of SSCC can also meet the workability requirements after adjusting the amount of raw materials.
