Bulk Density and Void Percentage Test for Aggregates
The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) 1963, or BS 812-2:1995. The procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a). The bulk density or unit weight is the weight per unit volume (mass per unit volume or density

Effect of Aggregates on the Properties of Concrete
It is based on the percentage voids in the aggregate after compaction as per IS 2386-1963 part-1. This test gives a value called as angularity number. The percentage voids are calculated as follows: A single sized aggregate is filled in a metallic cylinder of three litre capacity. The aggregate is compacted in a standard manner and percentage voids calculated. The voids can be found out by

A Detailed Guide on Grading of Aggregates.
The basis for mixing coarse and fine aggregates of specific fineness modulus is the presence of voids or open spaces when the aggregates are packed together. In pure coarse aggregates packing may leave 30-40 percent voids, which can be removed only by filling with finer particles. Similarly, in fine aggregates also, voids are left that have to be filled with still finer particles (of cement

Difference Between Fine and Coarse Aggregate Civil
Dolomite aggregates, crushed gravel or stone, natural disintegration of rock are the major sources of coarse aggregate. 5: Surface Area: The surface area of fine aggregates is higher. The surface area of coarse aggregate is less than fine aggregates. 6: Function in Concrete: The voids between the coarse aggregate are filled up by fine aggregate. Coarse aggregate acts as inert filler material

Classification of Aggregates Based on Size and Shape
Irregular aggregates may result 35- 37% of voids. These will give lesser workability when compared to rounded aggregates. The bond strength is slightly higher than rounded aggregates but not as required for high strength concrete. Angular Aggregates. The angular aggregates consist well defined edges formed at the intersection of roughly planar surfaces and these are obtained by crushing the
