Past studies on mechanical properties of grout were critically investigated and classified. Small scale and large scale samples were cast using cube and cylindrical moulds. Samples were left undisturbed to cure for various time intervals ranging from 1 to 21 days. Effects of sample scaling on the Uniaxial Compressive Strength (UCS) of Minova Stratabinder HS were studied, using a universal compression testing machine. In addition, rectangular samples were cast to investigate bending resistance of the grout product. Four point bending test was carried out on the samples with curing time ranging from 1 to 21 days. It was found that compression resistance of the grout increased with respect to curing time and initial studies on flexural strength showed that the bending resistance of grout reduced with prolonged curing times.
