Aggregate Sizing Explained - Chaney Enterprises

Jan 15, 2016  For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.

Nov 20, 2019  Each of the mentioned morphological indices is just calculated for one aggregate. In this study, 200 particles were randomly selected from each size fraction out of four size groups for one aggregate sample. Therefore, the average value of each index has to be calculated for a total of 200 aggregates of each size group.

The Coarse Aggregate Test (ASTM C127 and AASHTO T 85) is simply a volume determination by displacement of water. A basic test can be performed with a woven-wire basket and water container , or the complete test can be performed more efficiently using a specific gravity bench for suspended weighing of the specimen from an electronic balance.

The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

The Second group performed the reduction of the coarse aggregates by method of Quartering. The sample originally had a weight of 11 kg that needed to be reduced to a specific testing size that is able to represent the composition of the entire original sample. The method of quartering was repetitive. The group had to perform the method twice.
