The American Concrete Institute (ACI) defines CLSM as having a compressive strength less than 1,200 psi, however most current CLSM applications require unconfined compressive strengths of less than 300 psi. This lower strength is more than comparable with strength of compacted soil backfill, but is necessary to allow for possible future excavation.

Choosing Granite for Grave Markers. When trying to memorialize a lifetimes worth of memories, especially when creating a memorial monument to a lost loved one, the buyer, of course, must ensure that the materials used are not only beautiful, but long lasting. This stands to reason, without arguement in fact, becuase these monuments are final, permenant remembrances left behind.
