A mobile concreting apparatus and method which may be used, in particular, for on-site construction of swimming pools. It includes a vehicle supporting a plurality of containers, each adapted to contain one of the ingredients of concrete. Each container is provided with its own ingredient feeder which feeds the ingredients to a mixing device mounted on the vehicle to create a concrete slurry. The slurry is transferred from the mixing device to the surface to be coated by a structure including a slurry pump, a hose and a nozzle. Each ingredient feeder can be individually varied in the rate at which it feeds its ingredient so that the relative composition of the slurry, and the flow rate of the slurry, can be rapidly and selectively varied on the job site to meet the particular requirements for each job. In addition, feed rate settings which provide a desirable composition and overall feed rate can be noted and reproduced on subsequent occasions when the same composition and feed rate are desired.

A mobile concreting apparatus for preparing a wet concrete slurry, from flowable solid ingredients therefor and water, and applying the wet slurry to a surface at a job site, the concreting apparatus comprising, a plurality of containers, each adapted to contain one of the flowable solid ingredients
A mobile concreting apparatus for preparing a wet concrete slurry, from flowable solid ingredients therefor and water, and applying the wet slurry to a surface at a job site, the concreting apparatus comprising, a plurality of containers, each adapted to contain one of the flowable solid ingredients, a plurality of separate ingredient-feeding means, one for each ingredient, each of said ingredient-feeding means being connected to an associated one of said containers for feeding the ingredient contained in said container therefrom, a plurality of control means, each said control means being connected to an associated one of said ingredient-feeding means for individually controlling the feed rate thereof, mixing means connected to said ingredient-feeding means for receiving and mixing the ingredients fed thereto, water supply means connected to said mixing means for supplying water thereto at an individually controllable rate, said mixing means mixing the flowable solid ingredients and the water to a wet concrete slurry, a vehicle connected to and carrying said containers, said ingredient conveyor means, said control means and mixing means; a hose, a nozzle connected to one end of said hose for applying concrete to the surface, and pump means connected to said mixing means and the other end of said hose for pumping the wet concrete slurry through said hose at a feed rate which is controllable independently of the feed rates of said ingredients to said mixing means.
