Aggregate Angularity & Elongation
Aggregate shape properties affect performance and workability of a mixture. Gilson equipment measures performance factors such as aggregate angularity and elongation, as well as uncompacted void content.
- Void Content measures the angularity, sphericity, and surface texture of fine and coarse aggregates.
- Proportional Calipers are efficient devices that quickly determine percentages of elongated and flat particles in coarse aggregate fractions.
- Flakiness & Elongation of Aggregates are measured using a thickness gauge and a length gauge to hand-try particles when determining flakiness index and elongation index.
