Length Gauge (Elongation Index)

Category:
  • 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.

Aggregate size fractions:

    • 6.30 – 10.0 mm
    • 10.0 – 14.0 mm
    • 14.0 – 20.0 mm
    • 20.0 – 28.0 mm
    • 28.0 – 37.5 mm
    • 37.5 – 50.0 mm
  • CM 0165: Lenght Gauge (Elongation Index)
