Abstract: A system for monitoring and reporting sensor data associated with the delivery of concrete from a provider site to a client site by a concrete delivery mixing truck having a status sensor capable of obtaining slump related data is provided. The status sensor obtains slump related data which is read by a computing device that calculates a slump value, compares the slump value to a delivery slump value, and indicates that a transmission event has occurred if a difference between the delivery slump value and the calculated slump value exceeds a tolerance level. If a transmission event has occurred, event data associated with the transmission event is collected and delivered to a remote location or device.

Abstract: A method for delivering concrete to a construction site comprises charging concrete ingredients into a concrete delivery mixing truck, mixing the ingredients, to form concrete of a slump, monitoring the slump of the concrete, adding water to the concrete to adjust the slump, storing the slump in a memory device on the concrete delivery mixing truck at least a plurality of times during delivery of the concrete, displaying the slump on a display device on the concrete delivery mixing truck, substantially repeating the method, unloading the concrete at the construction site, and downloading contents of the memory device to a computer located at a dispatch site for the concrete delivery mixing truck via a wireline transfer.
