In this Concrete Logic Podcast episode, Seth, Rich, and Dr. Jon discuss the potential issues with water-to-cement ratios in concrete production. They highlight the challenges of using new cement and fly ash materials, as well as the variability in water content and cement quantities. The conversation emphasizes the importance of managing risk and the need for accurate calculations to ensure the desired concrete properties.

The episode revolves around the need to re-educate construction industry designers and engineers about the changing definitions and standards in concrete production. The speakers discuss the importance of communication, risk management, and practical problem-solving in the field.

Takeaways 

• The use of new cement and fly ash materials can introduce variability in water-to-cement ratios in concrete production. 
• Managing risk and accurately calculating water-to-cement ratios is crucial for achieving desired concrete properties. 
• Moisture probes and variations in water content and cement quantities can further complicate the calculation of water-to-cement ratios. 
• Concrete production involves a balance between book Crete (lab calculations), lab Crete (batch plant production), real Crete (on-site delivery), and street Crete (field adjustments). 
• The construction industry needs to re-educate designers and engineers about changing definitions and standards in concrete production. 
• Practical problem-solving and risk management are essential in the field.
