This demonstration shows Sika's new one coat traffic coating systems. Sikalastic®-720 One Shot is a two-component, integral texture, fast-curing, aliphatic, elastomeric polyurethane waterproofing coating intended for vehicular and pedestrian traffic. Applied in a single step, Sikalastic®-720 One Shot replaces the need for a base coat and multiple topcoats. Sikalastic®-726 Balcony One Shot is a two-component, aliphatic, elastomeric polyurethane traffic coating system that has both superior flexibility and abrasion resistance. Easily applied in a single coat, with or without primer, and designed for pedestrian traffic, specifically balcony and pedestrian applications.
The general sentiment around construction and modern technology is that the industry has been slow to embrace it. While this is true of the past, the current and future construction industry is all about modern technology. Not only does technology help to make the industry safer (something that has been a struggle for a very long time), but it is helping contractors to take back control of their budgets, to make smarter choices about project planning and equipment and is, consequently, pushing the green-construction trend forward. The purpose of this presentation is to provide a summary on the current technologies being used in the construction industry with a focus on concrete and to dig even further as to how these can be applied to repair projects. It will provide case studies on how using technology to bring ambient and concrete temperature, relative humidity and strength (among other) data online can help contractors be more efficient.
The prestressed beams in the Hampton Roads Bridge Tunnel Approach Spans were fabricated in about 1960 (west bound lane) and 1970 (east bound lane). The spans are 50-ft and 75-ft, respectively. The brackish water environment caused corrosion and failure of the bottom strands and deterioration and spalling of the cover concrete in many beams. A project in 2018 strengthened 30 of the more deteriorated beams as an alternative to posting or replacing the bridges. Carbon fiber composite wrap (CFCW) and external post-tensioning (PT) were used to strengthen the beams. Prior to construction, a PT mockup was done with one 50-ft (flexible filler) and one 75-ft (grout) beam to demonstrate that the contractor had the materials, equipment and staff to successfully do the external PT. This presentation describes the project’s mockups and construction and the anticipated increase in strength to be obtained from application of the CFCW and external PT.
Join us for an exciting hour showcasing new initiatives of ICRI; innovations at the chapter level; and a high energy panel discussion exploring lessons from the pandemic that are re-shaping our industry.
The demonstration will show the repair of cracks in concrete using structural polyurethane injection without pumps, ports or cutting, featuring Roadware 10-Minute Concrete Mender and Easy Injection System. This no cutting method generates almost no dust, making silica dust mitigation much easier.
Demonstration will show the use of an anti-washout additive for use in cementitious repair systems. The demonstration will show systems with and without the additive to exhibit the system’s function in water. The additive holds the mortar together to reduce loss of paste material into the surrounding water. This reduces water contamination and improves the performance of the hardened state concrete.
We will provide a brief presentation on the AET team, the AET services and business, how we operate as a team and perform our testing services, and what benefits we can provide our customers. We strive to get to know our clients well, educate them, and provide innovative, multi-disciplinary, and personalized service.
This demonstration will show FastPatch DPR, an easy to install, long-lasting repair material for distressed pavement that can be applied in warm or cooler climates. It can be used with FastPatch Kicker (accelerator) to form a fast-curing permanent repair that is ready for traffic in a short period of time. DPR has excellent adhesion, absorbs impact and is freeze-thaw resistant. It can easily create smooth transitions and ultra-tough level surfaces. Its minimal site preparation and fast cure times reduce traffic interruptions. The product is completely odorless making it also suitable for indoor applications.
This demonstration will take the audience through the entire process involved in the safe and effective installation of our GeoTree RenewWrap CFRP product.
The application of nondestructive testing and evaluation for detecting existing defects and anomalies in concrete structures will be presented. Proper inspection and assessment is an integral part of a successful repair and rehabilitation. A well-defined inspection will help asset owners and their consultants in identifying the location and extent of existing defects, and enabling them in selecting proper repair materials and optimizing the area that needs rehabilitation. Moreover, NDT methods can help identify potential defects that are not visible to the naked eye, such as early-stage delamination, corrosion, and other durability related issues. In this presentation, several cases in Canada will be demonstrated, where the results of nondestructive testing and evaluation have been used to help consultants and contractors with cost-effective and reliable repair planning. Applications of ground penetrating radar, ultrasonic pulse echo tomography, seismic tomography, will be discussed.
