Durability performance of structural concrete containing fine aggregates from waste generated by marble quarrying industry
Highlights Marble quarrying produces huge volumes of waste that is simply dumped. Concrete mixes with 0%, 20%, 50% and 100% fine marble aggregates were tested for durability. Results were compared with those of concrete with granite, basalt and river sand. Fine marble aggregates proved to be suitable for structural concrete.
Abstract The aim of this research is to assess the durability performance of concrete containing various percentages of fine aggregates produced from the waste generated by the marble quarrying industry (0%, 20%, 50% and 100% of the total volume of fine aggregates). The workability and bulk density of fresh concrete were measured and the water absorption by capillary action and immersion, together with the carbonation, chloride penetration and drying shrinkage of hardened concrete, were determined. It was concluded that the durability properties of concrete containing fine aggregates of granite, basalt and river sand tend to improve, remain constant and decrease, respectively, with the incorporation of fine aggregates from marble quarrying waste. However, these changes do not compromise the use of these secondary aggregates in structural concrete.
