The Length Gauge is designed to determine the elongation index of coarse aggregates, identifying particles whose length exceeds 1.8 times their mean sieve size.
This evaluation is critical in assessing aggregate shape characteristics, which can significantly influence the mechanical properties and durability of construction materials.
The gauge comprises six precisely spaced pins mounted on a robust base, facilitating accurate measurement across various aggregate size fractions.
Designed for ease of use in laboratory settings, the device ensures compliance with BS 812-105.2 standards, providing reliable performance for quality control and research applications.
