In recent years there has been a renewed emphasis on improving durability and increasing service life of structures. It is becoming increasingly apparent that the financial impact of rehabilitating structures that have failed prematurely due to improper design and construction methods is enormous. Owners and the general public are demanding that bridges, roadways, parking structures, marine structures, and other buildings be designed to last in excess of 100 years to reduce the time and frequency of repairs throughout the life of a structure. One way to increase service life is to design, specify, and build structures using high-performance concrete. High performance concrete incorporates advanced materials including supplementary cementitious materials, chemical admixtures, design details, and construction techniques to improve the durability and long-term performance of structures.
This course will help design engineers develop details and write project specifications to enhance concrete durability. Suggestions will be provided for designing and specifying concrete that can resist failure mechanisms such as corrosion, alkali-silica reactivity, sulfate attack, and freezing and thawing. Recommendations will also be provided for special applications such as mass concrete, self-consolidating concrete, and high-strength concrete.
Topics Covered:- Concrete in Extreme Conditions
Concrete is often the material of choice for structures subjected to severe conditions. This seminar will review potential failure mechanisms such as freezing and thawing, chemical attack, and corrosion. - Concrete Details
Details of reinforcement, joints, and embedded items are key to durable concrete structures. Recommended details will be presented for various extreme conditions. - Quality Concrete Construction
A review of quality concrete construction including the materials used, batching and delivery methods, and construction methods will be provided. In addition,
this review will cover the basics of quality control and quality assurance programs for concrete construction. - Performance-based Specifications
Methods for specifying concrete in terms of performance-based criteria to assure durability in all climates will be presented. The role of the engineer, contractor, and concrete supplier in building durable concrete structures will be discussed. - Advanced Construction Methods
Advanced construction methods will be presented including concrete placement techniques and curing methods. - Concrete Testing
A review of concrete tests used for quality control and quality assurance will be presented in addition to other tests used for durability. Background information will be provided on the significance and variability of the tests. - Solving Potential Problems
Potential problems with concrete both in the plastic and hardened state will be discussed and recommendations for solving and reducing these problems will be
provided.

This course is intended for engineers who design concrete structures exposed to harsh environments such as bridges, roadways, plazas, parking structures, marine structures or any building with exposed concrete. Nearly every structure has one or more components that are potentially subjected to a harsh environment including freeze-thaw and chemical attack. Engineers must have a good understanding of these failure mechanisms to provide effective design solutions. Contractors and product suppliers will also benefit from this seminar.
