To Determine Crushing Strength of given Aggregate- Concrete
Jun 19, 2016Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Coarse Aggregate Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called Coarse Aggregates. Fine Aggregate
