Flaky and elongated aggregates
WebMar 27, 2024 · Aggregates that are flaky and elongated. If an aggregate’s length is more than its breadth and its width is greater than its thickness, the aggregate is both flaky and elongated. Furthermore, mixing concrete with certain kinds of particles is not recommended. The production of such aggregates frequently arises from inadequate … WebDetailed Solution. Cubical aggregate has maximum strength in concrete as it has good packing and strength in all direction. Rounded aggregate is not suitable for concrete. Flaky means have less thickness, elongated means having more length. These aggregate can be easily crushed and having a minimum strength.
