The Benefits of Precision WaterSystem & Precision TemperatureSystem for COMMANDbatch Randy Willaman [email protected] 614-799-0600 x5230 Session Objective Describe how Command Alkon’s Precision Water and Precision Temperature Systems for COMMANDbatchcan improve the quality and consistency of concrete produced, saving time and money for our customers.
  • With Precision Water System (PWS) the producer can reduce wet/rejected loads, truck in yard time, eliminate load touch up and trips to the slump rack.
  • Precision Temperature System (PTS) dynamically adjusts water ingredients using a lowest cost method to ensure the concrete maintains the right properties until placement.
  • BAT-001 The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch Achieving consistency is a challenge
  • Loads too wet
  • Perform automatic or manual dry up activity
  • Loads too dry
  • Have trucks spend extra time at slump rack or under plant
  • Both situations waste time and money
  • Trucks must remain in yard while mixing
  • Each driver interprets what is a 4” (100mm) slump
  • If yield is thrown off or a load rejected then it’s an extra trip.
  • Drivers may or may not empty the drum
  • BAT-001 The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch Presenting Precision Water System
  • What is Precision Water System?
  • Acombination of hardware and software for COMMANDbatch. The software processes the signal from the bin moisture probes to accurately measure the amount of moisture in a variety of aggregate materials.
  • BAT-001 The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch Total Moisture Compensation 180 Precision Water Systems shipped to date
  • PWS Software Module
  • PWS Moisture Interface Controller Junction Box (MIC)
  • Up to 12 Moisture Probes
  • BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Why Precision Water System ? Adding moisture measurement all aggregates can:
  • Allow more cost effective blending of aggregates
  • Reduce slump and strength variations – this can lead to reduction of cement in mixes across the board
  • Reduce dry up loads and truck time in yard – direct impact on productivity
  • Reduce variability at job site – less time on job
  • BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Precision Water System Database with history of all samples Multiple bin-material-probe combinations Visual diagnostics to aid calibration Capture moisture test readings with the click of a button Simple entry of weights for calculations BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Precision Water System Calibration BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Integration with COMMANDbatch
  • System includes default calibrations for a range of materials, allowing immediate use of thePrecision Water System until bake outs and final calibration occurs.
  • Calibrations automatically adjust when materials are changed
  • Provides long term information for QC regarding performance.
  • Replacement probes can be calibrated with one bake out!

User Comments Plantsville, CT “We have recently installed Command Alkon's PWS (Precision Water System) in our plant's two sand bins. […] we have come to rely on them and have not been disappointed. [….] you need to run your own tests and input the data (Command has made this extremely quick and easy) […] We will, at some point, be adding these to our #8 and #67 (and possibly #6) bins.” Gary Radocchio See Gary's full comments on LinkedIn... BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Key Factors of Success
  • Training and Personnel
  • Enforcement of consistent and repeatable processes across the entire organization.
  • All departments must buy into the concept (Production, Technical, and Sales).
  • All areas of the business have to fully understand what the benefits of the system are and how to use it properly
  • BAT-003 Precision Water System Precision Water System Questions BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Precision Temperature System
  • What is Precision Temperature System?
  • A combination of hardware and software for COMMANDbatch. The software processes the signals from the material temperature probes and then adjusts hot/cold/chilled/ice ingredients to achieve the target mix temperature using the lowest cost method. BAT-001 The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch Why Precision Temperature System?
  • Hydration is an exothermic reaction, meaning it generates heat, and that reaction goes faster when the concrete is hot.
  • When the reaction is rapid, the crystals grow quickly but don't have time to grow strong.
  • Early strength will be higher but 28-day strength suffers.
  • If the concrete is about 18° hotter than normal (for example, 88° instead of 70°), the ultimate compressive strength will be about 10% lower. Source: http://www.concretenetwork.com/hot-weather-concreting/problem.html
  • BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Problems with hot concrete As the cement sets up, slump decreases rapidly and more mixing water is needed which can further reduce strength up to 10%. In integrally colored concrete variations in water content can result in significant differences in concrete color between adjacent pours. Source: http://www.concretenetwork.com/hot-weather-concreting/problem.html BAT-001. The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Problems with Hot Concrete
  • Thermal cracking – hot concrete will expand more, which means that as it cools it will shrink more and crack.
  • Crusting – accelerated curing by solar radiation can cause the top surface to set up even though the interior of the concrete is still plastic

The Benefits of Precision Water System and Precision Temperature System for COMMANDbatch. Precision Temperature System
  • Producing concrete to a specific temperature can:
  • Preserve workability (established with Precision Water System!)
  • Reduce/eliminate the need to add water at the job
  • Protect against job site color variation due to added water by the contractor
  • Provide temperature documentation on the ticket when the truck leaves the plant.
  • Produce better 28 day strengths (think reducing cement usage…)
  • Reduce claims for thermal cracking and crusting
