Ready-mix trucks hold 9-10 cubic yards per truck. Suppliers price by the CY plus a short-load fee on orders under 4-5 CY. Pricing varies by mix design (psi rating, aggregate size, air entrainment, integral color, special admixtures).
When placing an order, specify: cubic yards needed (round up to next 1/4 yard), mix design (3,000 / 4,000 / 5,000 psi), slump, air entrainment for cold-climate exposure, any color or admixtures, and the delivery time window. Watch the delivery ticket on arrival — it lists actual CY delivered.
Estimators size ready-mix orders from the geometric volume of slabs, footings, walls, and columns plus a waste percentage (typically 5-15%). Order to the next 1/4 yard increment.
