Codes and standards are developed for use by design professionals; however, the use of codes and standards significantly impacts Owners and Contractors. The ACI 562 code was motivated by the poor performance of repaired concrete structures, specifically premature failure of repairs and limited durability of repaired structures. Development of the code was intended to benefit owners and contractors by improving performance and perceptions regarding repairs to existing structures.
Demonstration will show how to apply solvent-based concrete sealers and discuss the various considerations to keep in mind, tools you will need, how to prepare your surface area, ideal environmental conditions for use of the sealers, the step-by-step application process, and how to safely clean up the area following application.
This is your opportunity to learn what’s happening with ICRI. 2020 President Mark LeMay will host a recap of the past year, with 2021 President Elena Kessi providing some highlights of what to expect in the near future. We will update you on our newest class of 40 Under 40 recipients and acknowledge our Supporting Members. This is also our opportunity to introduce to you the association’s 2021 Board of Directors and express gratitude to those remarkable volunteers whose technical and administrative committee service ended in 2020.
This demonstration will highlight the various product forms that can be integrated in a retrofit solution for extreme loading, that the product utilizes existing retrofit construction implementation practices and provides a lighter-weight retrofit solution when compared to retrofits that utilize standard or high-strength concrete solutions, and has superior multi-threat mitigation performance when compared with other concrete retrofit mitigation solutions for extreme loading events.
This session will describe the use of tensile pull-off (bond) testing for concrete repairs and bonded overlays. It will provide guidance on applications of the test, industry standards and guidelines, acceptance criteria, proper testing procedures, appropriate equipment, and interpretation and reporting of test results. Bond is important because it relates to structural requirements (e.g. for strengthening and structural repairs) and for durability requirements (e.g. for overlays and cosmetic repairs). Testing of bond is needed to verify that the specified bond requirements have been met and a satisfactory result has been obtained.
Moisture accumulation and water leakage into retail, commercial, and residential habitable spaces, including industrial facilities and below-grade parking structures, is the number one construction defect claim in our industry. The entire building envelope is a moisture barrier. Below-grade moisture barriers are required to keep water from leaking “into” and/or “out from” the structure. Water leakage inflow or outflow, and moisture accumulation within, can lead to health, safety and environmental issues involving the cost of operations and facility maintenance. Active water leakage, intermittent wetness, cavity wall moisture accumulation, and vapor transmission, can lead to costly problems: mold and mildew development, corrosion, contaminated water clean-up and disposal, slippery surfaces, and property damage.
This demonstration covers MiraGard Granite, a water-based dual component, self-crosslinking acrylic resin binder specifically designed for use as a decorative vinyl flake broadcast system to simulate the depth and texture of natural granite stone. The product is moisture vapor permeable and can be used as a beautiful decorative topcoat over new concrete or existing concrete needing repairs whether exterior, interior, slabs-on-grade or elevated slabs. It is also rapid curing and can be completed in one day with fast return to service typically in as little as only 24 hours, and offers outstanding durability and wear resistance, UV stable for superior color retention and weathering resistance, good resistance to moisture absorption, environmentally friendly and VOC compliant and water-based for easy clean-up.
This presentation will look at how technology is used to perform condition assessments at height and in places with difficult access utilizing a virtual toolbox that includes a wide range of instruments and tools for non-destructive evaluation and testing, and a fleet of drones, each of which has a different use. The presentation will discuss how to use drones and tools at height; how the industry is using drones in new ways; and how some municipalities are changing policies to adapt, especially with regard to facade inspections.
