RESEARCH

You are invited to the inaugural meeting of the new Minnesota Concrete Council ACI Chapter that will be held Tuesday, April 2 at Midland Hills Country Club in Roseville.  The presenter will be Cathy French, Ph.D., P.E. (University of Minnesota)

The American Concrete Institute expects to publish “ACI 318-19: Building Code Requirements for Structural Concrete,” in 2019. The new edition will be the first since the reorganized format was published in 2014 and will include new and updated code provisions along with updated color illustrations for clarity.

ACI expects 318-19 to include new code provisions on topics including transverse reinforcement and shear in wide beams, hanger reinforcement, bi-directional interaction of one-way shear, and reference to ACI certifications. Existing provisions expected to receive significant updates and clarifications include two-way shear strength, ordinary walls, seismic loads, reinforcement detailing, analysis, and numerous materials requirements. Analysis methods for two-way slabs and provisions on shearheads and composite concrete columns are expected to be removed.

Specifically, in this presentation, Dr. French will provide more in-depth information on ACI 318-19 updates including the introduction of high strength reinforcement, new shear provisions for non-prestressed concrete, and the introduction of screw anchors and shear lugs. French will highlight some of the background behind the new code provisions. This presentation will be of general interest to structural engineers who design reinforced concrete systems.

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

Cost to attend this event is $35 after March 26 or $25 early-bird before March 26.  Registration opens at 11:30 am.  Lunch will be served at noon and the presentation will begin at 12:30 pm.  The event will conclude at 1:30 pm.

Take advantage of the opportunity to obtain the ACI Flatwork Finisher Certification. This valued and important certification is specified in many projects across the US. The Minnesota Concrete Council is pleased to be able to offer this certification program to the Minnesota concrete community.

ACI CONCRETE FLATWORK FINISHER / TECHNICIAN, HOW DO THEY DIFFER?

A Concrete Flatwork Finisher is a craftsman who has demonstrated the ability to place, consolidate, finish, edge, joint, cure and protect concrete flatwork. A Concrete Flatwork Technician is a person who is knowledgeable about proper procedures to place, consolidate, finish, edge, joint, cure and protect concrete flatwork, but who as yet has not accumulated sufficient work experience to qualify as a concrete flatwork finisher.

Both programs require knowledge in the following areas of concrete construction:
• Basic concrete technology
• Concrete mix proportioning
• Concrete control tests
• Proper use of finishing tools
• Placing, consolidation, and finishing
• Edging, jointing, curing, and protection

ACI will grant certification to those applicants who obtain a passing grade on the written examination, and either:

A. Possess one year (1500 hours) of approved flatwork related work experience and successfully complete the ACI performance examination orB. Possess 3 years (4500 hours) of approved work experience and successfully complete the Alternative Performance Affidavit.

The work experience must include placing, consolidation, finishing, edging, jointing, curing, and protection of concrete flatwork. Verification of the amount and range of work experience by the applicant’s employer(s) is required.

The Federal Highway Administration (FHWA), sixteen state departments of transportation, and four national associations representing the concrete paving industry have come together in a pooled fund project to bring together newer testing technologies to maximize concrete pavement performance. Minnesota is currently participating in this multi-year pooled fund project and shadow testing portions of the current AASHTO PP-84 standard practice. As part of this effort, the FHWA brought the mobile concrete trailer (MCT) to the I-35 concrete paving project near Forest Lake, MN. The speaker will share the results from the FHWA MCT as well as additional results from past and upcoming shadow testing projects.

The presenter will be Robert Golish, PE (Minnesota Department of Transportation).

Registration opens at 9:30 am.  The presentation begins at 10:00 am and will conclude by 11:30 am.
