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.
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 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.
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.
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.
ICRI in-person conventions consist of numerous networking opportunities. In many cases, we catch up with old friends who we have not seen in a while, and get to know new friends. Great stories abound, including how ICRI members came to be involved in the organization. Tune in to hear some of these stories in a relaxed, “sitting-at-the-bar” exchange among notable ICRI leaders.
Technology is not limited to innovative materials or equipment on a jobsite. Digital technology is changing how teams operate and is dramatically increasing efficiency and effectiveness. Cloud-based project management software allows key stakeholders to consolidate project data on to one mobile platform for easy collaboration. The entire project team, from general contractors, specialty contractors, owners, architects, engineers, conservators, and others can exchange data and documents with the tap of a screen. Communication between the field and the office is streamlined where everyone has access to real-time project details. This helps avoid duplicate entry errors and rework because teams built from an outdated drawing. In addition to drawings and details, project management software brings contracts, submittals, RFIs, billings, safety reporting, meeting minutes, photos, and financial reporting into one platform.
Shotcrete has been used widely for rehabilitation and retrofit of concrete structures. More and more large infrastructures, in particular, in the hydro power industry, is using shotcrete for major rehabilitation and retrofit. Recently, the US Army Corps of Engineers has been engaged in structural modifications to reinforced concrete draft tube exits from the turbines in the Ice Harbor Lock and Dam located on the Snake River, Washington. This presentation details the structural modification to the draft tube which was successfully completed using wet-mix shotcrete.
This session on Structural Strengthening with Fiber-Reinforced Polymer (FRP) Composites provides a comprehensive exploration of the methods, materials, and considerations involved in enhancing the performance and resilience of structures.
