ABSTRACT:
A computer controlled pumping and measuring system is used to dispense chemicals into a concrete mix. The redundant use of positive displacement pumps and flow meters ensure that any problems with the chemical dispensing are immediately caught. The computerized control system may be operable to control exact batch configurations of concrete and aggregate in conjunction with the chemical dispensing, as well as provide precise mixture control and recording of the various components.
