Abstract:The durability and dimensional stability of concrete containing zinc slag as sand is reported in this paper. Concrete mixtures at different water-cement-ratios were prepared by replacing equivalent volume of sand up to 70% by ISF (Imperial Smelting Furnace) slag. The mechanical properties, leaching of toxic metals, durability parameters, and dimensional stability of SRM (Sand Replaced Mixtures) were examined in comparison with CM (Control Mixture). The results showed equivalent to CM strength at all replacement levels; leaching of toxic metals within acceptable limits; abrasion resistance comparable to CM for up to 60% SRM; permeability comparable to CM in most of SRM samples; lower than CM initial shrinkage; carbonation resistance better than CM; chloride diffusion resistivity comparable or better than CM; and, steel corrosion resistance better than CM. Overall, the experimental results ensured the suitability of ISF slag as sand in the production of durable and sustainable concrete with overall very good performance.
