True or False: CLSM needs to reach its specified compressive strength before it can be loaded.

The correct answer is that CLSM (Controlled Low Strength Material) needs to reach its specified compressive strength before it can be subjected to loads. CLSM is designed to have lower strength compared to traditional concrete, often used for fill or backfill applications since it provides ease of placement and reduced labor costs. However, despite its lower strength characteristics, it still must develop a certain level of compressive strength to ensure stability and integrity in the applications for which it is used. Loading it before it reaches this strength could lead to settlement, structural failure, or compromise the performance of the surrounding structures or systems.

In specific applications where CLSM is utilized, waiting for it to achieve the specified strength before applying loads is crucial for the safety and effectiveness of the overall construction or engineering project. This stipulation applies universally to ensure that the material performs as intended under load conditions.
