    When the length of aggregate is greater than 180 of its mean dimension (thickness and width combined) then it is considered elongated. Aggregate is deemed flaky and elongated when it satisfies both the previously mentioned conditions. Elongated or flaky particles exceeding 15 should be considered unsuitable for concrete use.
