What is a key benefit of using controlled low strength material in construction?

Controlled low strength material (CLSM) is specifically designed to flow easily and fill voids in construction applications while requiring minimal compaction efforts. This characteristic offers significant advantages in construction, particularly in projects where achieving tight compaction would be difficult or impractical. By not needing compaction, CLSM can be placed quickly and efficiently, reducing labor costs and the time required to finalize a project.

The flowable nature of CLSM allows it to conform to the shape of the area being filled, ensuring complete coverage without the risk of voids that can occur with traditional materials that require extensive compaction. This makes it particularly useful for backfilling trenches or as a base material in various applications, as it ensures stability and support while simplifying the installation process.

The other options refer to qualities that may not apply directly to the benefits of CLSM. While it has specific strengths, its standout feature is truly its ease of placement, especially in contexts where compaction is challenging. This combination of simplicity and effectiveness is what makes controlled low strength material valuable in construction practices.
