General Standard: ASTM Grade / BS Standard
Application: Aggregate Testing
Usage: Construction Material Testing Laboratory
Country of Origin: India
Material & Construction Material: Wood and Mild Steel (MS)
Design: Precision slots designed to determine the elongation index of aggregates
Function Measures aggregate length to determine the elongation index.
Helps identify elongated particles affecting concrete strength and workability.
Testing Range Not applicable for aggregates:
Passing 6.30 mm sieve
Retained on 50.0 mm sieve
Test Procedure Perform sieve analysis with standard sieves.
Discard aggregates >50.0 mm and Separate aggregates into size fractions.
Weigh and store each fraction in labeled trays.
Measure particles using the length gauge slots
Length gauge is an ASTM-standard measuring device that uses a retractable rod and sensi ...
