Post-batching CMA dosing into concrete
The present invention relates to mitigating the deleterious effect of clays, which are born or conveyed by sand aggregates, crushed rock, gravel, and other aggregates used in the manufacture of concrete, upon the dosage efficiency of cement dispersants or other admixtures which are added into concrete. Instead of introducing the entire cement mitigation agent (CMA) into the aggregate material at a quarry or upon batching in the mix plant in a singular, upfront dose, the present invention comprises combining at least 51% and up to 100%, and, most preferably, at least 75% and up to 100%, of the total dosage amount of the CMAs into a given concrete mix batch during the transit portion of the delivery between initial batching at the mix plant and the pour event at the job site.
