Abstract
Enormous waste generated from quarry sites require disposal and acute shortage of
dumping sites necessitated the need to conduct an investigation into the possibility
of recycling these waste materials for use in the construction industry leading to a cleaner environment. The current study investigates the characteristics of concrete
containing quarry waste as partial replacement of fine aggregates up to 40% by
weight. The properties investigated are the workability and strength development
characteristics of the concrete specimens in addition to characterization of the
materials properties. Results revealed that the compressive strength at days 7, 14,
21 and 28 curing age were 6.92 N/mm², 8.63 N/mm², 14.33N/mm² and
17.27N/mm² respectively. The study revealed 13.62% increase in strength over the
control mix (0% quarry waste) which had strength of 15.20 N/mm² at 28 days.
Quarry waste not exceeding 20% is therefore recommended in concrete.
