Enhancement of the tensile strengths of rock and shotcrete by thin spray-on liners

[Display omitted] •Paper deals with tensile strength enhancement by thin spray-on liners (TSLs).•Tensile tests on rock and shotcrete, coated/uncoated with TSLs, are reported.•Tensile enhancement is typically ∼30% for brittle rock and >40% for shotcrete.•Bending tests on rock beams showed similar...
