This research involved experimental tests on concrete specimen, using glass as coarse aggregate in the production of concrete for rigid pavement. The crushed glass was used to partially replace the coarse aggregate at 0%, 5%, 10%, 15%, 20%, 25%, 30% and 40% with a constant mix proportion of 1:2:4 and watercement ratio.

The global consumption of natural sand is very high, due to the extensive use of concrete or mortar. The fine and coarse aggregates generally occupy 60% to 75% concrete volume (70% to 85% by mass) and strongly influence the concrete's fresh and hardened properties. Now a day's sand is becoming a very scarce material. Natural sand deposits are being depleted and causing serious threats to ...

crushed limestone sand concretes, although lower than those of siliceous sand concretes, remain completely comparable. ShiCong and ChiSun [32] showed that the workability of crushed fine stone CFS concrete mixes was decreased with an increase in CFS content probably due to the angular shape of the CFS when compared to river sand. Also, Donza et al. [33] found that when crushed sand was ...

The concrete mixes were developed by adding coarse aggregate to the mortar mixes used in Task 1. For the control mixes, the coarse aggregate consisted of crushed limestone with a maximum nominal aggregate size of 3/8in. For the internal curing mixes, the limestone was replaced with bottom ash with a maximum nominal size of 3/8in.
