Module 1 covers the introduction to the program and discusses the definition of reinforced concrete and common types of reinforced concrete deterioration, focusing on deterioration resulting from embedded metal corrosion and its effect on existing structures. The process leading to reinforcing steel corrosion is further discussed, including the effects of chlorides, carbonation and access to the reinforcing steel (including cracks and joints, low quality concrete, and reduced concrete cover).
The Certification course, ICRI Concrete Surface Repair Technician—Grade 1, is for individuals who want to become a qualified inspector for concrete repair and qualifies the individual to perform pre- and post-placement inspections and testing.
This option is available for those who purchased the Certification course and completed the training Modules 1-5 and the knowledge exam — but failed one or more of the tests in the performance exam.
From the days of boiled Linseed oil, to the discovery of membrane forming cures, to the development of carbon dioxide injection; curing has evolved to accommodate the demands of the construction industry. This presentation will look back at the early standards developed by ASTM, contrasting them to the standards that are currently under consideration. There are many ways to cure concrete, this presentation will review the various product options framed in the context of weather. Lastly, the presentation will explore the various methods discussing the features and benefits of the common curing practices of today.
Dallas City Hall and Plaza are recognized by many due to the opening scenes of Dallas, the television show. What is less known is that the structure is a significant early example of bonded post-tensioned concrete which was utilized throughout the superstructure and two-story parking garage constructed beneath the plaza. Opened in 1977, the parking garage is a two-way bonded post-tensioned concrete slab with unreinforced drop panels supported by flared circular concrete columns. The garage covers two city blocks, extends under two adjacent multi-lane streets, and supports mature landscaping, pool, fountain, and up to 11’-0” of soil. In 2017, several square feet of a drop panel fell from the structure and subsequent observations found multiple locations of drop panel and column capital failures. A structural investigation including destructive and non-destructive testing, and analysis of the existing structure was undertaken to determine the cause of the failures.
In this presentation, industry expert David Whitmore will explain how various factors govern the service life of zinc based cathodic protection systems and how we can achieve accurate service life designs.
The demonstration will cover the basic steps, products, and processes involved with dying and polishing concrete. The equipment, tooling, chemicals, and processes used to achieve a polished floor will be demonstrated.
EDCC is an extremely novel and first of its kind application for use primarily in the seismic retrofit of unreinforced masonry walls. This spray-on technology incorporates a highly sustainable and cost-effective mixture of recycled admixtures that have proven to be extremely effective at greatly enhancing the ductility and strength of unreinforced structures. Its ease of placement and unique flexural advantages make it very unique in the field of seismic upgrade with the potential for additional applications with other infrastructure improvements.
