Agitating speed is usu- ally about 2 to 6 rpm, and mixing speed is generally about 6 to 18 rpm. Mixing at high speeds for long periods of time, about 1 or more hours, can result in concrete strength loss, temperature rise, excessive loss of entrained air, and accelerated slump loss.

While travelling to the job site the drum is turned at agitating speed (slow speed). After arriving at the job site, the concrete is completely mixed. The drum is then turned for 70 to 100 revolutions, or about five minutes, at mixing speed.

Open-top agitators which are truck-mounted bodies of special shape with rotating blades in which previously mixed concrete is kept in motion during delivery. And open-top nonagitating units which may be specially shaped bodies or ordinary dump bodies mounted on trucks for delivering previously mixed concrete but without provisions to keep the concrete in motion during delivery.

The homogeneity of concrete is maintained after mixing and during delivery by turning the drum at agitating speed. Agitating speed is usually about 2 rpm to 6 rpm, and mixing speed is generally about 12 rpm to 18 rpm.

concrete mixtures containing water reducers, water-reducing retarders or hydration stabilizers would be affected by extending their transit time from 60 to 90 minutes, with a potential for additional testing up to a 120-minute delivery time.
