Practical Method for Mix Design of Cement-based Grout
2017-1-24application of more sand in the mix will reduce material cost but will also reduce the grout flowability. A higher water-cement ratio is required if more sand is used in the mix to maintain the grout flowability. For instance the 1 2 mix must have a water-cement ratio of 0.65 to pass the flow cone test, meanwhile the 1 1.5 and 1 1 mixes only
