What is the strength threshold for CSLM to be excavatable?

The strength threshold for Controlled Strength Materials (CSLM) to be excavatable is typically around 150 psi. At this strength level, CSLM achieves a balanced performance, allowing for sufficient load-bearing capacity while still being workable for excavation process post-curing. Below this threshold, the material may not provide adequate support for structural stability, and above it, excavation becomes increasingly difficult, potentially impacting the efficiency and feasibility of construction operations. As such, 150 psi is considered the practical limit for ease of excavation while still maintaining the material's functional requirements.
