MCC | MN Concrete Forum: Near Surface Aggregate Reactivity & Petrography - What We Know

Date: November 29, 2018
Time:
  • 9:30 am - 11:30 am
Location: Midland Hills Country Club
Please See Registration Link Below
Description

The concrete petrographer is often called upon to explain the causes of deterioration of a concrete placement. The laboratory work of the petrographer includes identification of the cause(s) of distress through an examination of the concrete surfaces, paste and aggregate conditions. Sometimes the alkaline cement paste can cause dissolution of siliceous aggregates or cause chemical and volume changes carbonate rocks. These reactions are collectively called alkali-aggregate reactions. These reactions are deleterious when they cause enough expansive force within concrete to rupture the concrete despite the powerful bonding within the cement paste. This presentation will cover what we commonly look for when assessing Alkali Aggregate Reactions (AAR) in hardened concrete.

The presenter will be Gerard Moulzolf, PG (American Engineering Testing).

Attendees will be emailed a certificate of attendance for one professional development hour (PDH) at the conclusion of the event.

There is no charge to attend this event but pre-registration is required because space is limited. 

Date: Thursday, November 29
Time: Registration opens at 9:30 am. The presentation will begin at 10:00 am. Q&A will begin at 11:00 am. The event will conclude no later than 11:30 am.
Location: Midland Hills Country Club (2001 Fulham Street, Roseville, MN)
