CIP 16 - Flexural Strength Concrete

CIP 16 - Flexural Strength Concrete WHAT is Flexural Strength? Flexural strength is one measure of the tensile strength of concrete. It is a measure of an unreinforced con-crete beam or slab to resist failure in bending. It is measured by loading 6 x 6-inch (150 x 150-mm) con-crete beams with a span length at least three times the depth.

CIP 17 - Flowable Fill Materials

CIP 17 - Flowable Fill Materials WHAT is Flowable Fill? Flowable fill is a self-compacting low strength material with a flowable consistency that is used as an economi-cal fill or backfill material as an alternative to compacted granular fill. Flowable fill is not concrete nor it is used to replace concrete. Terminology used by ACI Committee
