This webinar will review issues that should be addressed when preparing a specification for concrete repair. ICRI developed an editable specification titled “Guide Specification for Structural Concrete Repairs” that can be used by design professionals. The webinar reviews the specification and discusses decisions that should be considered when developing a concrete repair specification.
Galvanized corrugated metal and concrete underground culverts are common infrastructure in North American highways and stormwater management. A shotcrete lining is a cost-effective and efficient method to strengthen and significantly extend their useful life.
This session will explore the differences between bonded and unbonded topping slabs, discuss materials- and installation-related causes of failures, and provide guidelines to properly implement each type of topping slab.
This presentation is based on the updated revisions to the original document entitled Guide for the Selection of Grouts to Control Leakage in Concrete Structures. This webinar addresses the selection of chemical grouts typically used to control and/or mitigate the ingress of water in concrete structures, specifically cracks and joints.
Discover the innovative and sustainable advantages of shotcrete, a highly efficient concrete placement technique that offers engineers unparalleled flexibility in shaping and reinforcing concrete structures while achieving superior strength and durability.
This unique webinar specifically focuses on the technology, process & application of using high-pressure water to remove concrete, called Hydro Demolition.
Concrete is the most widely used construction material and can be durable for hundreds of years; however, the main cause of concrete deterioration is from corrosion of reinforcing steel. Steel is thermodynamically unstable and will eventually oxidize to a lower energy state. The rate of deterioration in new and existing structures can be modeled to predict the service life based on the severity of the service environment, the concrete quality, the ingress of deleterious materials, and other factors to various degrees of success. This presentation will provide an overview of many of the service life models currently in use and provide an evaluation protocol for their application related to both new and existing structures.
Matching concrete sounds simple, but there are many factors that affect color, texture, and aesthetics. There is often a challenge with using modern cementitious materials for matching older and historically manufactured cements. Whether your project is historic or contemporary, this presentation will outline materials and methodology that are important to understand when concrete matching is important. With many mid-century buildings coming of repair age, this is a critical time for understanding these concepts. The presentation will include the fundamentals of concrete materials, how cementitious materials affect concrete color, how to use color measurement technology in developing a color match mix design, how aggregate exposure affects aesthetic perception, and other helpful tips when it comes to matching concrete for durable and aesthetic results. Regionally available materials will vary, but the methodology for color matching durable repairs is fundamentally the same.
