Why is Slump Mandated in Project Specifications?
October 5, 2022 from 3:00pm to 4:00pm Mountain Standard Time
Colorado Convention Center - Mile High 1
With the advances in concrete technology over the last 50 years, why is slump still being mandated in project specifications? This presentation will begin by covering the history of the slump test and the development of the water/cement ratio. Then we will discuss the advent of water-reducing admixtures and show how they have advanced. We will discuss why slump should now be "means and methods" decided on by the contractor. We will also discuss how different placement methods, weather, and what is being poured should determine the slump, not the EOR. This will all be presented with the idea that the w/cm ratio is not compromised, and technology is allowing the contractor to work with a higher slump. This will be explained with supporting documents from ACI, ASCC, and ASTM.
LEARNING OBJECTIVES
- Understand the history of the slump test and how it came to fruition.
- Understand the history of the water reducing admixtures and why they are important.
- Identify why different placement methods, weather, and what is being poured should determine slump
- Explain why slump should be "means and methods" and not mandated in project specifications.

TRACK SPONSOR - IconX, LLC
ICONX LLC produces and distributes the IconX Shear Connector line. With a new 5"- 6" connector being introduced to the family this year, we are now able to support you on projects with insulation thickness from 2" all the way up to 6" and everything in between, making IconX the smart choice for your high performance insulated wall panels. The foundational goal of the IconX System was to develop a shear connector to make insulated wall panels longer, stronger, and stiffer than previously available. It was also important for the connector to work with any rigid insulation in panels reinforced with mesh or rebar. Due to the composite action that the IconX Shear Connector facilitates between the wythes of concrete, the total concrete thickness can be reduced by 3 to 4 inches over conventional non-composite panel design, saving you material costs and potentially reducing your crane size and footing and foundation sizes. Simply put, we can do more for less. We are committed to helping you have a successful project with us. Contact us by phone or email, or come meet us at the TCA show to discuss what we have to offer.
