Abstract
A method and system for initiating a majority percentage of chemical admixture dosage into a delivered concrete load preferably just before arrival of the concrete delivery truck at the delivery pour site, such that a maximized slump (or slump flow, or other slump characteristic) increase occurs just before discharge/pour. The invention employs a concrete slump management system having a processor that is programed to consider time of pour (discharge) and stored data that includes dosage response (change of slump characteristic) of the concrete mix due to past additions in the same type of concrete mix, and thus maximizes pre-pour increase in slump characteristic while minimizing or avoiding the risk of overshooting the slump target as well as limiting the time required for adjusting concrete to attain the target slump value at the jobsite.
