ABSTRACT:
An apparatus for high capacity production of high-fluidity, colloidally mixed cement slurry. Water and cement dust are combined at metered rates by a premixing assembly which discharges into a mixing tub. The high-speed, high-shear pump recirculates the material through the tub to produce the colloidally-mixed slurry. The high-fluidity slurry may be provided to a second pump, preferably of the positive-displacement, progressive-cavity, rotor-stator type, for supplying the slurry at a metered rate. Finished foam material may also be provided to the slurry metering pump at the metered rate, so the materials are mixed to form a foamed cement grout in which the weight and quality of the material is precisely adjustable.
