Israel LHLDY-0362 Coarse Aggregate Flow Time Tester

This instrument is used to determine the time required for a certain volume of coarse aggregate to pass through a fixed size opening, indirectly evaluating the angularity of the coarse aggregate. This method is applicable to the angularity determination of coarse aggregate with a nominal maximum size of 9'~19mm.

Product Description

This instrument is used to determine the time required for a certain volume of coarse aggregate to pass through an opening of a fixed size, indirectly evaluating the angularity of the coarse aggregate. This method is suitable for determining the angularity of coarse aggregate with a nominal maximum particle size of 9'~19mm.

Complies with the national mandatory industry standard JTG 3432-2024 "Highway Engineering Aggregate Test Procedures"
