Murphy Knives, www.rmurphyknives.com Advertisers INDEX Automated Slump Management Verifi LLC has launched the Verifi Disperse, a new system that enhances and extends the Verifi Process Control Sys‐ tem, by automatically adding not only water, but also dis‐ persants to the concrete mix, while in transit. The automated slump management ensures that concrete will always arrive at the job site within the target slump rate. The system delivers significant improvements in control‐ ling concrete slump and other plastic concrete properties, resulting from the addition of admixtures much closer to the point of discharge. Through Verifi Disperse, slump can be increased at the job site on contractor request without compromising strength. Water‐cement ratio can be main‐ tained, while still providing workability through disper‐ sants. Another benefit is the system's ability to allow for the full truck capacity to be used in high slump mixes, by enabling the truck to travel with low slump concrete and then automatically dose disper‐ sant to high target slump upon job site arrival.
