A quick setting grout made from a mixture of cement/sandwater and an additive is needed for a tunnelling project

Two trial mixes have been made with the following combinations of grout and additive.

5 litres of sand/cement/water + 1 litre of additive =6 liter of grout mass=12.487kg

5 liters of sand/cement/water =1.5litre of additive=6.5liter of grout mass=12.98kg

(a) From this information find the densities of the sand/cement/water mixture and the additive in kg/litre, giving your answers accurate to three decimal place.

(b) Using this information determine the quantities needed to make 5 litres of grout with a density of 2.000kg/litre
