Abstract:
Strength and slump tests are reported for ready- mxied concrete mixed in stationary mixer and hauled in a standard truck-mixer-agitator for various periods up to 7 hr. One group of tests was conducted during early spring and another during summer to study effect of temperature. Wash analyses made on con- crete samples before starting haul and at end of haul Effect of retempering by adding water to restore lost slump was studied.
