  • New methods for accurate water dosage in concrete central

    Jan 25, 2008 · Equipment. In order to evaluate the calibration method, tests were performed in a Skako-Couvrot central mixing plant delivering ready-mixed concrete. This plant is a Point P production unit located at Argentan, France. The concrete components were weighed and then homogenized in a 1.5-m 3 planetary mixer. The mixing power was measured at a rate of 1 measurement per second.

    Modern plants can weigh aggregates with an accuracy of up to ± 0.5%. If the amount of moisture in a batch of sand or aggregates varies from between 2% to 10% then this will affect the accuracy and proportions of the weighed materials since water is effectively being weighed and not dry materials.
