Concrete Essentials Seminar Series

The Concrete Essentials Seminar Series, presented by the American Concrete Institute, is a two-day educational event taking place 28-29 November 2018 at The Big 5 Heavy. This seminar series will give participants an in-depth look into topics including concrete durability, repair, self-consolidating concrete, and more.

 

The American Concrete Institute is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational & training programs. With more than 20,000 members spanning over 120 countries, ACI members represent the best in the concrete community. During this session, learn about the history of the American Concrete Institute and how it is currently working for a future where everyone has the knowledge needed to use concrete effectively to meet the demands of a changing world.

12:30 - 13:30 Concrete Basics

Many issues related to construction can be alleviated by a fundamental understanding of the basics of concrete. This starts with knowledge of the standard components of a concrete mixture including cementitious materials, aggregates, water, and admixtures and their importance on the properties of fresh and hardened concrete. The combination of these materials in various proportions can produce mixtures suitable for a wide range of applications and placement methods. Once placed, the concrete must be properly cured to develop its intended properties. The fundamentals of each step of this process are covered in this course.

The structural design of reinforced concrete structures is facilitated by ACI 318, developed by experts in design and analysis. This document sets the minimum requirements for life safety.

It also deals with durability of the structure by setting performance and prescriptive requirements on the concrete materials. The protections for sulphate exposure and permeability will be reviewed. In addition, there are numerous structures where the owner desires a defined service life. The definitions of service life, the environmental exposures and the performance and prescriptive requirements will be reviewed, with an emphasis on reliability engineering methods. ACI is currently developing a durability code to supplement the requirements of ACI 318. These topics will be reviewed in terms of specification and production of concrete where durability, not strength, is the governing durability criteria.

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

Self-Consolidating Concrete (SCC) technology has been available in North America for 20+ years. It is highly flowable concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without segregating and without the use of mechanical consolidation. It has the same properties as typical concrete but has substantial additional benefits that include reduced placement labor, improved constructability, better consolidation in congested areas, and surface finish properties that make it very beneficial for many applications.  This presentation will review the unique mixture proportioning, quality control, and formwork design considerations that accompany the use of SCC and the advantages of its use in specific applications.

ACI 318-14, Chapter 17, covers anchorage to concrete for both cast-in-place anchors and post installed mechanical and adhesive anchors. It also lists installation and inspection requirements for some installations. An overview of the failure modes for anchorage will be provided along with a discussion of the installation, inspection, and certification provisions contained in the chapter.

This presentation will introduce the ACI 562-16, “Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary.” This is the first U.S. code produced specifically for the repair of reinforced concrete structures. Topics covered in this presentation will include:

  • Need for a repair code
  • 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 does the code benefit the owner

A new guide document for the code with additional information and project examples that help users interpret the code requirements will also be highlighted.

The newest edition of ACI 318, “Building Code Requirements for Structural Concrete (ACI 318-14),” was completely reorganized from a designer’s perspective. This course will help you get acquainted with the new organization so that you can learn to quickly navigate the code and demonstrate how you can ensure that your design fully complies with ACI 318. Design examples will be used to demonstrate the use of the code and also introduce the ACI design requirements for elements of structures often used for design in seismic regions. These design examples will cover requirements for:

  • Strut-and-tie models
  • Walls and boundary elements
