Abstract:
1. A system for managing one or more conditions of concrete in a concrete delivery vehicle from immediately after concrete is loaded on said vehicle at the batch plant and the loaded ingredients are mixed until discharge from said vehicle, comprising: a mixing drum for containing concrete and mounted on said concrete delivery vehicle; a controller mounted on said concrete delivery vehicle; a chemical additive supply coupled to the controller and mounted on said concrete delivery vehicle, the chemical additive supply comprising two or more supply containers each containing a different chemical additive; and fluid connections between said supply containers and said mixing drum; a temperature sensor mounted to said mixing drum, and optionally one or more of a hydraulic pressure sensor mounted to said delivery vehicle to determine an amount of hydraulic pressure to rotate the said mixing drum, and a drum speed sensor mounted to the said deliver vehicle or the said mixing drum; said controller obtaining information on a condition of said concrete, and in response causing said chemical additive supply to selectively deliver chemical additive to said concrete, wherein the controller collects data on the condition of said concrete from two or more of: a temperature measurement of said concrete; rate or amount of measured temperature change of said concrete measured during a time period; and a measured amount of energy required in mixing said concrete; and measured completion of mixing of said concrete.
