Concrete Mix Design - sginstitute

American Concrete Institute Method of Mix Design (ACI–211.1) This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include, among other modifications, the use of entrained air. In 1970, the method of mix design became the responsibility of ACI committee 211.

Jan 01, 1976  A pumpable concrete mix must be able to maintain its consistency in pump and pipeline. Where rapid changes occur in cross-section of the pump or pipe, 2 or at high rates of placing pump pressures as high as 5MPa (5 MN/m ) may be needed, with corresponding severe pressure gradients in the concrete.
