摘要： The present invention allows for better control over strength in concrete mixes and mix designs, while minimizing the over-use of cement and promoting sustainability within the industry. Disclosed are novel method and system which employ a diagnostic delta data (DDD) curve, or, in other words, data that displays a curvilinear relationship when plotted on a visual graph, as obtained by considering the differences (e.g., subtractive differences or ratios) as between (i) target slump and target (or maximum) water content, and (ii) slump and water content values as determined using an automated slump monitoring system which measures slump and water content in the concrete mix during delivery. This DDD curve can then be compared to monitored delta slump and delta water content for later or other deliveries, such that adjustments can be made to the concrete mix or mix design, in a manner that encourages avoidance of cement over-dosing or over-prescription.

摘要： Method and system to measure and monitor the grey water content in a rotating concrete mixer drum mixer truck using a sensor attached to the interior of the concrete mixer drum. By measuring the grey water content before a batching process takes place, the batched water (and cement content and admixture type and content) can be modified in order to maintain expected performance of the batched load in terms of both strength and rheology, or more simply, some or all of the grey water can be discharged from the concrete mixer drum before batching.
