Abstract
Disclosed are dosing methods for 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 added into concrete. Instead of introducing the entire clay mitigation agent (CMA) into the aggregate material before or during batching in the cement batch plant in a singular, upfront dose, the present invention comprises administering CMA doses on at least two instances in a rotatable truck-mounted mixer drum, wherein at least 21%-100% of the total CMA added into the concrete is added after initial batching of water, cement binder, and clay-bearing aggregates in the rotatable truck-mounted mixer drum during the transit portion of the delivery between initial batching at the cement batch plant and the pour event at the job site.
