Crushing Value of aggregates Mould: Length gauge and Thickness gauge: Length Gauge (Elongation Index BS), is used for determining the elongation index of aggregates. Thickness Gauge is used to determine if the aggregate particles are to be considered as flaky, i.e. their thickness is less than 0.6 of their nominal size. Sieve Shaker
