Elongated Aggregate
Definition:
Elongated aggregates are those aggregates whose length is greater than 1.8 times their mean dimension, i.e., their length is more than 1.8 times their width or thickness.
Criteria to determine elongated aggregates:
According to IS 2386 (Part 1), if aggregates completely pass through a sieve of size 75 mm and are retained on a sieve of size 60 mm, the aggregates will be known as elongated aggregate if its length is not less than 121.5 mm.
Explanation:
- The size of the sieve used to determine elongated aggregates is 75 mm and 60 mm. The aggregates should pass through the 75 mm sieve and be retained on the 60 mm sieve.
- The length of the aggregates should be measured along their longest dimension.
- To determine whether an aggregate is elongated or not, the length of the aggregate should be compared with its width or thickness. If the length is more than 1.8 times the width or thickness, the aggregate is considered elongated.
- According to IS 2386 (Part 1), if aggregates pass through the 75 mm sieve and are retained on the 60 mm sieve, and their length is not less than 121.5 mm, they are considered elongated aggregates.
Conclusion:
Elongated aggregates have a negative impact on the workability and strength of concrete. Therefore, it is important to identify and remove them from the aggregates before using them in concrete. The criteria to determine elongated aggregates should be strictly followed to ensure the quality of aggregates used in concrete.
