Brief Description of Research Project

The overarching purpose of this research is development of knowledge and a novel technique to enhance properties of Eco-Bridge-Crete, FR-SCC and FR-SWC for higher crack resistance and improved flexural properties in construction and repair by taking advantage of hybrid fibers, chemical admixtures (shrinkage reducing agents and expansive agents) and lightweight sand. A binary or ternary system of EA, SRA and LWS with selected fibers will be optimized to enhance shrinkage cracking resistance, mechanical properties and durability of the targeted mixtures. The incorporation of fibers with EA, SRA and LWS can increase the flexural properties and help to replace a portion of steel reinforcement bars in flexural members or reduce thickness of repair overlays without compromising flexural strength/toughness and crack resistance. The selected mixtures will be used in large-scale members to assess their structural performance in construction and repair.
