Presented by Henry Prenger, PE, Technical Service Engineer with LafargeHolcim
Our Industry is driven by specifications; from the inspection of concrete plants, the development of concrete mixtures, the time period when concrete is allowed to be placed, the plastic properties of the concrete, all the way to the ultimate strength of the hardened concrete. Specifications are designed to provide protection to the owner while providing guidance and restrictions to the engineer, the ready mix producer, and the concrete contractor. Financially, specifications can also make or break a contractor or ready mix producer. The speaker will discuss recent and proposed specification changes and discuss their potential affects on concrete properties and concrete cost. If you are a Registered Engineer or Architect looking for Continuing Education Hours, we can provide a certificate to you at the meeting for you to self report.
