Summary:

Controlled low-strength material (CLSM) is commonly used as a backfill in utility trenches and other applications. The fill must gain sufficient strength to allow for early repaying and support traffic loads. However, the ultimate strength of the fill material must not exceed 50 to 200 psi (0.344 to 1.38 MPa) to allow for re-excavation of the trench should repairs be necessary. Concern over the long term strength gain of CLSM has prompted the National Ready Mixed Concrete Association to initiate a 2 year cooperative study that will investigate mix parameters that control long term strength. Comparisons of standard strength tests with removeability of the in-place fill will be made. The study will also evaluate ASTM provisional test methods for CLSM. Preliminary results are reported in this paper
