2010-12-09· Concrete prices can fluctuate regularly, based on the cost of the extraction of the components of concrete, and the cost of fossil fuels. At the time of writing, concrete costs about $90-$115 per cubic yard. 3000 psi concrete, which is the most commonly used grade, costs around $100-$110.This is just the cost of concrete itself, not including the various necessary peripheral processes.

(ii) The water lubricates the aggregates and it facilitates the passage of cement through voids of aggregates. This means that water makes the concrete workable.

Even if your local batch company quotes a price of $100 per cubic yard, it still might refuse to sell you a single cubic yard without charging you a short load fee that could range from $50 to $200. Before ordering, ask the batch company representative about tack-on fees, which can include:
