ACI Concrete Flatwork Associate and Advanced Concrete Flatwork Finisher Certification Review and Written Examination

Concrete Flatwork Associate

A Concrete Flatwork Associate (formerly Concrete Flatwork Technician) is a person who has demonstrated knowledge (via a written examination) on proper procedures to place, consolidate, finish, edge, joint, cure and protect concrete flatwork.

Certification Requirements:  ACI will grant certification to those candidates who obtain a passing grade on the written examination.  The two-hour written examination is closed-book and consists of approximately 50 multiple-choice questions. The passing grade for the written examination is 70%.

Recertification is necessary every five years and requires successful completion of a written examination OR 10 hours documented continuing education from an approved source. Individuals with Concrete Flatwork Associate certification can upgrade to Advanced Finisher status upon submittal and approval of sufficient work experience or combination of sufficient work experience and passing the ACI performance examination. Certification at the Advanced Finisher level is valid for the remainder of the original Associate certification period.

Advanced Concrete Flatwork Finisher

An Advanced Concrete Flatwork Finisher (formerly Concrete Flatwork Finisher and Technician) is a craftsman who has demonstrated the knowledge AND skills and/or experience necessary to place, consolidate, finish, edge, joint, cure and protect concrete flatwork.

Certification Requirements:  ACI will grant certification to those candidates who obtain a passing grade on the written examination PLUS either:

Possess 4,500 hours of actual on-the-job finishing* experience (approximately three years of regular full-time work) OR possess 1,500 hours of actual on-the-job finishing* experience (approximately one year of regular full-time work) AND successfully complete the performance examination**.

**MCC will NOT be offering a performance examination at this class, so anyone seeking Advanced Concrete Flatwork Finisher Certification at this class MUST possess 4,500 hours of actual on-the-job finishing experience.

Recertification is necessary every five years and requires successful completion of either a written examination, or a combination of 10 hours documented continuing education from an approved source and 4500 hours of verified continuing work experience attained within the previous 5 years.

*Finishing experience includes concrete placement, consolidation, jointing, curing and protection, finishing, form setting, prep work, rubbing, patching, and saw cutting. Verification of the work experience by the candidate's employer(s) is required.

Contractors want concrete to be as workable as possible to facilitate placement and consolidation without compromising performance in the hardened state. Concrete producers strive to consistently deliver expected performance attributes. Yet, hydration of Portland cement leads to a change in fresh concrete properties immediately after batching, most notably with respect to mix slump or workability. In air-entrained concrete mixtures, furthermore, modified slump can lead to changes in air content, typically a reduction, and potential rejection of the load. Invariably, rejected loads result in loss of revenue and reduced profits for concrete producers. This presentation will discuss workability retention and the various methods traditionally used to manage it. Additionally, an innovative, new admixture is introduced that provides workability retention without the adverse effects of current practices.

The presenter will be Joseph Daczko  (Master Builders Solutions)

Attendees who have fully participated in the webinar will receive a certificate of attendance for one professional development hour or 1 AIA CES LU.

This webinar was developed cooperatively by concrete-related associations from Minnesota, North Dakota, South Dakota and Wisconsin.  The goal of the cooperative effort is to bring a greater awareness of cast-in-place concrete to the design and construction communities via quality continuing education programs.
