The Aggregate Shape Gauge is designed to determine the shape index of coarse aggregate particles by assessing the ratio of length to thickness.
This evaluation is essential for understanding aggregate shape characteristics, which can significantly influence the mechanical properties and durability of construction materials.
The gauge facilitates the classification of individual particles, identifying those with a length-to-thickness ratio exceeding 3:1, which are considered elongated.
Constructed from durable steel, the device ensures longevity and compliance with international testing standards.
The shape index is calculated as the mass percentage of elongated particles relative to the total dry mass of the sample.
