Mirzaghorbanali, Ali and Gregor, Peter and Ebrahim, Zeinab and Alfahed, Abdullah and Aziz, Naj and McDougall, Kevin (2019) Strength properties of grout for strata reinforcement. In: 2019 Coal Operators' Conference, 18-20 Feb 2019, Wollongong, NSW, Australia.
Abstract
Past studies on the mechanical properties of grout were critically investigated and classified. Grout samples were cast using a specially designed dog bone mould. Effects of curing time on tensile strength properties were investigated, using a universal tensile testing machine for curing times intervals ranging from 1 to 28 days. In addition, various percentages of fly ash were added to cube grout samples. Fly ash mixed samples were cured for different curing times and subsequently subjected to Uniaxial Compression Testing (UCS). It was found that tensile resistance of grout samples increased with respect to curing time. Moreover, it was concluded that addition of fly ash to grout mixture increased the uniaxial compression strength of grout samples.
