Twisted Steel Micro-Rebar in Load-Carrying Concrete Walls

by Samhar Hoz, Jeff Novak, Luke Pinkerton   Concrete walls are widely used in building construction. Concrete is strong in compression; however, its tensile strength is only 8 to 15 percent of the compressive strength. Thus, plain concrete does not have good tensile properties. Cracks can develop due to loads, restrained shrinkage, or temperature changes […]
