PERFORMANCE OF LIGHTWEIGHT CONCRETE USING PALM OIL .
aggregate, tests on aggregate crushing value and aggregate impact value were carried out. It was found that the coarse and fine POC aggregates produce a density of kg/m 3 and kg/m, respectively, which were lighter than normal granite and sand as much as % and %. This is due to the porous nature of POC aggregates. POC absorbs excessive water which contributes to .

Pavement materials: Aggregates
· Then crushed aggregates are then sieved through mm sieve and weight of passing material (W 2) is expressed as percentage of the weight of the total sample (W 1) which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.

Strength and Durability Evaluation of Recycled Aggregate ...
· Aggregate crushing value (ACV) provides an indiion of the aggregate strength. Aggregate with lower ACV is recommended to ensure that the aggregate will be able to resist applied loads. The test was conducted on coarse aggregate of different grades. The ACV is calculated as the ratio between the weight passing sieve and the original weight. Values were in the range of 20–30, as shown ...
