A. MATERIALS:

1. Concrete shall contain cement, coarse aggregate, and fine aggregate with a minimum of 4,000 pounds of compressive strength per square inch at 28 days.

Concrete color, “weathered oak” from the Master Builder’s Color Chart, shall be added for deliveries to all locations except the optional Admin area. Additives such as non-chloride accelerator, fibers, superplasticizer, and set retardant shall be added as recommended by the manufacturer.

3. Deliver each load at the job site accompanied by a ticket showing the mix design number, volume of concrete, the weight of cement in pounds, and the total weight of each ingredient in pounds. Must also show the time at which the materials were batched and the reading of the revolution counter at the time the truck mixer was charged.

4. Air entrainment should be included in the concrete mix. And add mixtures to delay cure time to allow for the delivery to the project site if greater than 1-hour transit from mix site to placement location.

5. No re-tempering of partially hardened material is permitted. Do not use partially hardened concrete in the work.

6. Testing and verification of material compliance will be done on-site

C. BATCHING IN ADVERSE WEATHER:

1. Cold Weather: When the atmospheric temperature is below 40°F, or is likely to fall below 40°F during the 24 hours after placing, heat the materials before mixing, so that the temperature of the mix when deposited shall be between 65° and 80°F. Do not heat the mixing water or the cement over 160°F. Remove lumps of frozen material and ice from the aggregates before they are placed in the mixer.

2. Hot Weather: When temperatures are above 90°F, reduce the temperature of the concrete mix by using iced mixing water, and protecting aggregates and cement from direct rays of the sun. Do not place concrete exceeding 80°F.
