Mixing machine for mixing cement components with water to provide a pumpable slurry, and a method for its use. The machine includes a mixing vessel having an inlet for water at an average flow rate and for dry cement components, and a water tank for supplying water at a high flow rate to the mixing vessel and having an internal diaphragm separating the tank into water and air compartments. The water tank includes an inlet for admitting water to the water compartment and a conduit communicating the water compartment with the mixing vessel and capable of accommodating the flow of water at an average flow rate substantially greater than the average flow rate of water into the water compartment. The conduit includes a water meter and valve to monitor and regulate, respectively, the quantity of water supplied to the mixing vessel.
