RUSS-FLO – Flowable fill admixture is a dry powdered material that aids in producing a highly flowable and volume stable flowable fill mixture also known as controlled low strength material (CLSM), controlled density fill (CDF) and low strength mortar (LSM). The use of RUSS-FLO – flowable fill admixture results in improved flowability while reducing the amount of mix water required to obtain a flowable mix. RUSS-FLO – Flowable fill admixture is packaged in two layer plastic bags.
