Delivery of Ready-Mix Concrete

Ask the ready mix supplier how many days of lead time are necessary for an order and whether the concrete can be delivered at the time of day you want it (such as before dawn or early evening to avoid placements during the heat of the day). Giving your supplier ample notice will help to ensure priority service and on-time delivery.

time long enough to allow the hydration process to approach completion. With proper curing, hydration takes place very rapidly at first, and then decreases slowly for a long time. This allows the concrete to develop its strength and durability. Concrete needs continued moisture to develop its full potential. It should not dry out too quickly.
