Controlled low strength material (CLSM) is designed to provide a low strength, self-compacting fill material. One of the key characteristics of CLSM is that it does not need to be compacted like traditional soil fills. Instead, the material flows and settles into place, which eliminates the need for mechanical compaction. This property makes it advantageous for use in various applications, such as backfilling trenches or filling voids, as it allows for quicker and more efficient placement without the need for additional equipment or labor associated with compaction.

The other options involve processes or characteristics typically required in conventional construction materials. Mixing is essential to achieve a uniform blend of components in the material, testing for density is important to ascertain the quality and performance characteristics of the material, and ensuring a curved shape may apply to certain applications but is not universally required for CLSM. Therefore, knowing that CLSM does not necessitate compaction reinforces its utility in construction and applications requiring lightweight fill materials.
