Reports the tests of a variety of concrete mixes made in I-, 21/z- and 4-cu yd Jaeger truck-transit mixers. The mixing time in some cases-extending to 90 min. Purposes of the tests were (I) to determine the relation between the strength of the concrete and the time of mix, (2) the relation of time of mix to the degree of uniformity of the concrete produced, and (3) the relation of other observable features of the mixing operations to both strength and uniformity of output.
