Concrete Delivery Fixed Mixing Concrete Stations

Jan 26, 2014 · Weekend ready-mix delivery costs 5 percent to 10 percent more. Ready-mix companies allow four to five minutes for each yard delivered. After that, the clock ticks at $2 per minute. If concrete has to be pumped from truck to site, there are additional costs and charges.

WRA has been used primarily in hot weather concrete placing, pumping, and tremie. Careful concrete placement is required, as the initial setting time of concrete will take place an hour earlier. It is also shown that the use of WRA will give a higher initial concrete compressive strength (up to 28 days) by 10% compared to the control mixture.
