Abstract: This invention describes apparatus and method for recycling undelivered cement left as residue in cement trucks. Undelivered cement at the end of the working day is deposited on a shaker screen under action of high pressure water jets which trap large aggregate and force the large aggregate onto a first belt for collection. Sand, cement and water fall through the first screen onto a second screen which traps sand under action of high pressure jets that force the sand onto a second belt for delivery to a collection area. The remaining cement, water and slurry is collected in a trough and pumped to a settling tank having an auger that periodically mixes the water and cement to prevent hardening. A skimmer located at the uppermost portion of the settling tank collects clear water used to clean the aggregate and cement previously mentioned. The cement, water and slurry collected in the settling tank is used in combination with fresh sand and cement to provide a fresh charge to waiting cement trucks.
