Abstract:
This report describes the use of shrinkage-compensating concrete for a spillway chute invert. The contractor elected to use the Type K expansive cement alternate in lieu of the conventional Type II portland cement. A study was made to evaluate compressive strengths for various water-cement ratios, slump loss, restrained expansion, modulus of elasticity, and freeze-thaw durability. Quality assurance testing at the project consisted of casting standard compressive strength specimens and restrained expansion prisms for each of the 18 panels. This use of shrinkage-compensating concrete provided an effective means of crack control for a spillway chute invert slab.
