Highlights. Durability and mechanical properties of recycled concrete have been analysed. A total of 24 mixtures at ages of 28, 180 and 365 days were studied. The durability is lower but for lowers water/cement ratios the loss is less. The loss of mechanical properties is greater for lower water/cement ratios.

The workability of concrete is defined as the property of freshness that determines the ease and symmetry with which concrete can be mixed, placed, compacted, and finished. Workability of fresh concrete is a complex system of two essential parameters as follows: Consistency: The ability of fresh concrete to circulate constantly.

This concrete trial was prepared using only natural, fine and coarse, aggregates to show workability, measured by slump test [ 2 ], of 100 ± 20 mm. The concrete trial used for reference showed 461.7 kg/m 3 of cement content and 0.45 of water/cement ratio. Recycled concrete were made using the reference mix design just doing the substitution of ...

The workability was determined using the slump apparatus. The compressive, split tensile and flexural strengths of the hardened samples were evaluated using cubes, cylinders and beams of dimension 100 mm 3, 100 × 200 mm and 100 x 100 × 550 mm, respectively. Scanning electron microscopy (SEM) coupled with energy dispersive x-ray (EDX) was ...

The word "workability" defines an amalgam and composite of four concrete flow-making physical properties like mixability, transportability, mouldability, and compatibility. You can't ignore this physical parameter because of the fact that it effects the strength, durability, cost of labor, compaction effort, and also the final appearance.

Workability of the concrete depends on a number of interrelating factors. Water content, aggregate properties, use of admixtures, fineness of cement are the factors affecting workability. Water content: The increase in water content …
