Abstract

In the article the possibility of using surface blast-cleaning waste (copper slag based) as a replacement of fine aggregate in high performance concrete manufacturing was presented. Concrete with w/c ratio 0.45 and 360 kg/m3 dosage of cements: CEM I 42.5R, CEM II/B-V 42.5N and CEM III/A 42.5N was tested. The consistency measured in table flow test was assumed as 420 ± 30 mm so superplasticizer was used. The replacement rate of the fine aggregate 0–2 mm with the copper slag (CS) waste was 66 %. Concrete mixtures with sand served as reference. The performed tests focused on: compressive and tensile strength (both after 28 days), sorptivity, free water absorption capacity, Torrent air permeability, and chloride ingress depth after salt fog treatment. A freeze resistance test was also carried out according to PN-B-06265. The obtained results showed that the strength and some other tested properties of concrete mixtures with copper slag waste were similar or better than those of the mixtures with sand. The results of the tests indicate that the concrete with copper slag waste is more tight than the concrete with sand and therefore is more durable.
