Concrete mixer trucks deliver ready-mix concrete to job sites with on-board mixing. Truck capacities typically range from 8 to 14 cubic yards. Delivery is coordinated through ready-mix concrete suppliers. Typical delivery costs include a per-yard charge plus delivery fees (typically $150-$300+ per load). These trucks have rotating drums that keep concrete mixed during transport, preventing segregation. Concrete must be placed within 90 minutes of mixing. Trucks require level access and adequate maneuvering space. Concrete finishers manage the discharge chute and placement. Modern trucks include GPS tracking and automated dispatch. Common applications include building foundations, concrete floors, and sidewalks. Slump (consistency) can be adjusted at the plant based on project requirements.
