The measurement of fresh properties of cement-based grout containing waste marble powder

This paper shows the results of an experimental study conducted to investigate the effect of waste marble powder (WMP) on the fluidity (marsh cone flow time (MCFT), mini-slump diameter and plate cohesion meter (PCM)) and the rheological properties (viscosity and yield stress) of cement based grout (CBG) mixtures. The experiments were done with the CBG mixture including 0.75, 1.00, 1.25, 1.50 water-binder (w/b) ratios and 5, 10, 15, 20 and 25% content of WMP. Test results illustrated that the rheological properties of the CBGs had been improved greatly by the addition of WMP to grout mix at various w/b ratios. It was observed that the CBG mixtures showed a strong shear thickening behavior all WMP content and all w/b ratios. Moreover, the increase in the w/b ratio decreases the MCFT at the constant WMP content. Additionally, the increase in the percentage of WMP amount up to %15 did not effect on mini slump flow diameter, however the mini - slump flow diameter decreased above %15 WMP. (C) 2019 Elsevier Ltd.
