Early-Age Verification of DEF Potential

Sunday, October 29, 2023  3:30 PM - 5:30 PM

High concrete curing temperatures above 158°F can in some cases result in a condition called delayed ettringite formation (DEF) that can cause severe cracking and concrete deterioration. Occasionally a concrete member will exceed this temperature during curing, causing concern about the potential for DEF in the member.

Learning Objectives:
(1) Discuss mechanisms that cause DEF in concrete;
(2) Discuss mitigation methods for DEF in concrete;
(3) Discuss methods to determine if DEF will be a problem for a structure that experienced high temperatures during curing;

No presentations scheduled at this time.
