Oct 01, 2020  The results of the parametric study showed that increasing the concrete density, decreasing the slab depth leads to an increase in the failure strength, the failure rotation, and the ductility. In addition, increasing the flexure reinforcement ratio increase the strength but decreases the failure rotation and ductility.

Ductility is a desirable trait in an otherwise brittle concrete which is conventionally achieved via methods like introduction of steel reinforcement. While thin spray-on liner (TSL) is a material used in underground support systems to enhance the strength and ductility of rock and shotcrete, its application in concrete is a promising prospect.
