Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm ( in.) and generally between mm and mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pitrun gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...

After mixing, workability of the concrete was determined using slump test. It was confirmed that the slump values of concrete at different glass replacement level remained within the target slump range of 100–125 mm without changing the water content. The concrete was placed, compacted and surface finished with a smooth steel trowel in cube mold.
