COMPRESSIVE STRENGTH OF CONCRETE MADE WITH ELECTRIC ARC FURNACE SLAG AND RECYCLED GROUND GLASS AS REPLACEMENT OF COARSE AND FINE AGGREGATE

Concrete is one of the most studied industrial products with the aim of improving its durability, strength, and workability, as well as developing innovative alternatives in its production to reduce the environmental footprint (Rivera, 2013). This research validates the use of industrial waste generated in the department of Boyacá - Colombia, within the production of concrete for the construction of rigid pavements. The research followed several stages, beginning with the physical, chemical, and mechanical characterization of the materials and the design of the standard mixture following the ACI 211 methodology. Subsequently, the 25%, 50%, 75%, and 100% of the gravel was replaced by electric arc furnace slag (EAFS), and 20, 30 and 40% of the sand by the recycled ground glass (RGG). Finally, the compressive strength of the concrete mixtures was analyzed.

The purpose of this paper is to examine the effects of introducing waste materials sourced from factories in Kuwait as partial replacements of conventional concrete materials. Rejected ceramic products and unused electric-arc furnace slag were treated and partially replaced portions of coarse and fine aggregates, and the possibility of partially replacing cement was also examined. Initial results showed that all aggregate sizes can be replaced with either of the waste materials without compromising the concrete’s rheological properties or compressive strength. Additionally, pulverized ceramic powder was shown to improve the compressive strength of mortar cube samples. Finally, the two waste materials were combined in hybrid mixes that aimed to have the highest utilization of waste materials while maintaining (if not improving) the properties of a previously established benchmark self-consolidating concrete (SCC) mix. The results of this study show that waste materials sourced from landfills in Kuwait can be repurposed to replace portions of conventional construction materials in a self-consolidating, high-performance concrete mix with significantly better mechanical properties and higher compressive strength than that shown by a benchmark mix.

The mechanical behavior of basaltic volcanic ash (VA) and fly ash (FA) as a cement replacement under elevated temperatures is mainly investigated in the current study. For this, cement content has been partially replaced with and without the presence of electric arc furnace slag (S). Four distinct ranges of temperatures (200°C, 400°C, 600°C, and 800°C) were selected, and the modified mixes were subjected to these gradually elevated temperatures. Samples were cured and cooled by using air- and water-cooling techniques. Test results were established by examining the sample weights and compressive strength before and after the exposure of each temperature level. The pozzolanic potential of volcanic ash and fly ash samples was identified using the strength activity index. After analyzing the test results, it has been found that there is a significant effect on the compressive strength of mortar mixes at the early ages of its strength gain. However, at the later ages of curing, samples modified with volcanic and fly ash with the presence of electric arc furnace slag have shown a better performance than control mix in terms of strength and weight loss.

Abstract In this study the electric arc furnace slag was used as coarse natural aggregate substitute in concrete paving blocks production. The concrete mixture was defined by using weight proportions in the ratio of 1:2:3:0.51 (cement:sand:coarse aggregate:water) in order to obtain a compressive strength of 35 MPa. Four groups of concrete were prepared: a reference recipe and three others with the slag replacing the natural aggregate in the proportions of 25%, 50% and 75%. The compressive strength was not influenced by the slag content; however, it was influenced by the curing age, as the sample with 75% of slag addition had its compressive strength increased by 13.5% from 7 to 56 days. Water absorption presented a slightly reduction with slag addition. The results of compressive strength and water absorption met the Brazilian technical requirements, making the paving blocks suitable for use in light vehicle traffic. The results obtained in this study highlight the influence of the production process in the final quality of the steel slag, and the need of stablishing technical and environmental requirements to guide and promote the safe use of electric arc furnace slag in concrete.
