ACI Code Advocacy
Advocacy You Can Do! – Local Advocacy Is an Important Part of the Adoption Process
This presentation provides an overview of general building code development and applications, highlighting the need to reference ACI committee work in building codes. The use of model codes and reference standards is addressed. Understanding the politics, both the potential for support and opposition, for modifying building codes is described as a lead in to identifying opportunities to have a role in code advocacy efforts. ACI codes and many of its standards and programs are intended to provide for the good of the general public by providing minimum requirements for safety, health, and welfare. The benefits of exhaustive ACI committee work and mission of ACI as a technical professional society best serve the public where appropriate, current ACI requirements are integrated into the general building code and enforced.
- Describe ACI’s revised mission statement
- Summarize the components of building codes
- Explain the model code development process
- Identify model code development advocacy roles
- Explain the state code development process
- Identify state code development advocacy roles
ACI Certification, Now and the Future
This presentation will introduce and review new certification programs as well as what’s on the horizon.

ACI Reference Specifications: Unraveling Concrete Specs
The art of writing good concrete specifications can be a daunting task. ACI reference specifications are designed to help engineers easily and consistently write quality concrete specifications and benefit contractors through a consistent standard of practice. The most common reference specification for concrete construction is ACI 301, “Specifications for Structural Concrete.” This presentation will cover how to properly use reference specifications to enhance project specifications and minimize the amount of specification editing required for a project. Significant changes and updates to ACI 301 that help specifiers and contractors place more durable and resilient concrete structures will also be presented. These changes not only address some new issues, such as changes in minimum cementitious content, but also coordinate ACI 301-20 with the requirement of ACI 318-19. Topics covered in this presentation include:
- What are ACI specifications
- Common features of ACI specifications, using ACI 301
- Summary of the ACI 301 checklists
- Important upgrades in ACI 301-20
ACI Repair Code 562-19
This talk will introduce ACI 562-19, “Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary,” which is the first code produced specifically for the repair of reinforced concrete. A new guide document for the code with additional information and project examples that help users interpret the code requirements will also be highlighted. Topics covered in this presentation will include:
- Why a repair code is needed
- The philosophy behind ACI 562
- How the code promotes consistency in repair design
- Recognizing repair construction challenges
- Significance of a quality assurance program for successful repairs
- How the code can save the owner money
Adhesive Anchor Installer and Inspector Certifications

Changes to the Concrete Design Standard
This new edition of "Building Code Requirements for Structural Concrete" (Code) is the first since the reorganized format was published in 2014 and includes new and updated code provisions along with updated color illustrations for added clarity. The Code provides minimum requirements for the materials, design, and detailing of structural concrete buildings and, where applicable, nonbuilding structures. This presentation covers a few of the significant changes to this code including high-strength reinforcement, shear strength, development length, and shear lugs.
- Understand where higher grades of reinforcement are accepted and changes to the requirements for structural concrete to allow the higher reinforcement grades.
- Identify changes to development lengths for straight bars, hooks, and headed deformed bars.
- Learn the new requirements for post-installed screw type anchors and shear lug design for anchoring to concrete.
- Describe the changes to shear design provisions and equations.
This topic is both a contentious and unfortunately common issue. Often, the key to addressing cracking is learning how to properly determine the cause of the crack so it can be mitigated and prevented in future projects. Topics covered in this presentation will include:
- Causes and control of cracking
- Evaluation methods
- Crack repair
Durability – how do we measure it?
This presentation will discuss the importance of durability and current test methods. Topics covered in this presentation include:
- How to define durability
- Where to find durability requirements and guidance
- Commonly used durability tests for freeze-thaw and alkali-aggregate reactivity
FRP – Strengthening
Topics covered in this presentation include:
- Strengthening options
- Components and general properties
- System selection
- System design
Low Compressive Strength Test Results? What They Mean and Next Steps…
Compressive strength tests are used for concrete acceptance based on criteria defined in ACI 318 and ACI 301. Tests results not meeting these criteria are referred to as low strengths. This presentation covers the “low strengths” topic in detail and provides answers to questions such as: what is considered a strength test and what is not, what the minimum frequency of testing is, what the acceptance criteria for strength tests are, and how to investigate strength tests not meeting the acceptance requirements. In addition, steps needed by a concrete supplier, in case acceptance criteria are not met, will also be discussed. To better understand discussed concepts, the presentation will use statistical concepts and numerical examples. A list of reading resources will be provided for those interested to study it in more detail. Topics covered in this presentation include:
- Definitions related to strength testing
- Methods of sampling, fabrication, handling, and curing strength test specimens
- Acceptance criteria for strength tests
- Interpretation of strength test results not meeting acceptance requirements
- Investigation of non-compliant concrete
- Addressing low strength concrete issues in production
Mass concrete — How Big is Big?
What is mass concrete? ACI 207.1R defines mass concrete as any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of the cement and attendant volume change to minimize cracking. But how does one predict whether mass concrete problems will occur and what steps should be taken? This presentation will discuss how to identify mass concrete, ACI 301 requirements pertaining to it, and good construction practices. Topics covered in this presentation will include:
- Examples of mass concrete structures
- Identifying mass concrete in the field
- Specification requirements
- Factors influencing mass concrete
- Mitigation or design
Slag Cement for Sustainable Concrete Construction
This session focuses on the sustainable benefits of slag cement use. The presentation will cover how the use of slag cement can reduce the environmental footprint of a structure, help projects qualify for LEED accreditation, and contribute to enhanced concrete performance. Case studies will illustrate how different mix designs using slag cement can reduce carbon emissions while increasing the strength and durability of concrete. Attendees will also get a tutorial of the Slag Cement EPD and Life Cycle Assessment Calculator tool available to download on the SCA website.
Slag Cement in Concrete
This session covers the basics of slag cement use in concrete mix design as well as how slag cement enhances the strength, durability, and overall performance of concrete. Learn how to incorporate slag cement in combination with portland cement and/or other supplementary cementitious materials to reach your project’s desired outcomes, creating a less permeable and more sustainable concrete. Presenters will also review the various specifications and standards regarding slag cement use. The session will wrap up with case study examples of projects that used slag cement successfully in a variety of applications.
What does coal have to do with concrete?
The cement and concrete industries consume almost 20 million tons of fly ash, bottom ash, and synthetic gypsum annually. These materials are recovered following the combustion of coal in power plants generating electricity. This presentation by the American Coal Ash Association will provide an overview of the utility industry and a look at the future supply of these materials.
