Introduce to the UHPC Certificate Program: Fresh and Hardened Properties

Monday, November 4, 2024  11:00 AM - 1:00 PM, Grand BR Salon A

The UHPC Certificate Program is being developed by ACI Committee 239-E to introduce the concrete community to field and laboratory testing of UHPC. The certificate program is being rolled out by Committee 239-E in three modules. An overview of Module 1, which focused on General Knowledge of UHPC, was presented at the ACI Spring 2023 Convention in San Francisco. In Fall 2024, Modules 2 and 3 will be introduced through special sessions that will focus on collecting samples, characterizing fresh properties, and testing UHPC to characterize hardened properties.

Learning Objectives:
(1) Describe procedures to fabricate specimens made of UHPC in the field and laboratory;
(2) Explain how to measure fresh properties of UHPC through standard methods;
(3) Summarize procedures to characterize the hardened properties of UHPC;
(4) Describe durability testing procedures of UHPC.

Fabricating and Testing Specimens of UHPC

Presented By: Matthew Bandelt
Affiliation: New Jersey Institute of Technology
Description: This presentation will give an overview of procedures for fabricating and testing specimens of UHPC. A discussion of testing standards for UHPC will be presented, highlighting key differences from working with ordinary concrete materials. This talk is being delivered as part of ACI Committee 239-E’s development of the UHPC certificate program.

Testing UHPC Fresh Properties

Presented By: Robert Thomas
Affiliation: Clarkson University
Description: This presentation will describe procedures for testing the fresh properties of ultra-high performance concrete. Topics covered include flow and setting time of UHPC. This talk is being delivered as part of ACI Committee 239-E’s development of the UHPC certificate program.

Making and Testing UHPC Specimens in the Field

Presented By: Peter Seibert
Affiliation: UHPC Solutions North America
Description: This presentation will discuss considerations for making and testing UHPC specimens in the field. This talk is being delivered as part of ACI Committee 239-E’s development of the UHPC certificate program.

Testing UHPC Mechanical Properties

Presented By: Cesario Tavares
Affiliation: ICON
Description: This presentation will give an overview of special considerations that need to be made when testing the mechanical properties of ultra-high performance concrete. Topics covered include compressive strength, flexural performance, and static modulus of elasticity measurements. This talk is being delivered as part of ACI Committee 239-E’s development of the UHPC certificate program.

Testing UHPC Durability Properties

Presented By: Garrett Tatum
Affiliation: Ohio State University
Description: This presentation will discuss testing procedures for evaluating the durability properties of ultra-high performance concrete. Topics covered include length change, resistance to freezing and thawing, and chloride ion penetration. This talk is being delivered as part of ACI Committee 239-E’s development of the UHPC certificate program.
