WebSince CLSM is designed to be fluid, it can be easily placed as backfill in a hole. Soil backfill, even if compacted properly in the required layer thicknesses, cannot achieve the uniformity and density of CLSM. CLSM mixtures typically consist of water, portland cement, fly ash, and fine or course aggregates, or both. Some mixtures contain only ... WebCLSM may also be used as structural fill such as foundation support. For example, if weak soils are prevalent under a structure CLSM is effective in distributing the structure’s load over a great area. CLSM can also provide a uniform and level surface for foundation footings and slabs that might otherwise bear on uneven or nonuniform subgrades.
