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.
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.
Moisture-related floor covering and coating failures are a very costly and disruptive issue with the direct and in-direct costs associated with such issues estimated to be in the hundreds of millions of dollars each year in the United States alone. In this session, a brief overview of the previous sessions will be provided and experts in the field of slab moisture, concrete, testing and forensics will answer your industry questions related to the subject.
Richard Miller Treatment Plant is a 240 mgd cap. potable water treatment facility located in the California area of the Cincinnati, Ohio, US. After installing an advanced ultraviolet (UV) disinfection treatment system in 2013, GCWW became the largest water utility in North America to use UV light following sand filtration and granular activated carbon. The concrete filter gallery building was originally constructed in 1907 with 26 filters, with a 14-filter addition in 1937 and 7 filters added in 1964. After over 110 years of service, the structures started showing significant signs of deterioration, most commonly concrete spalling and reinforcing steel corrosion. This case study will highlight the methods used to evaluate the structures that involved conventional methods such as sounding, crack mapping, chemical and petrographic examinations, along with technology such as Half-Cell Potential/ICOR, Impact-Echo, Ground Penetrating Radar, and UAS (Drone) services.
The demonstration will show the ins and outs of Sika's FRP installation process with the multiple system options Sika offers to help with your needs for a proper install on site.
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.
This video will illustrate an example of how various sections of ACI 562 are applied in the execution of a complex repair project, the repurposing of a historic train deck into a transportation hub for light rail trains and busses. Methods of evaluation and analysis, as guided by ACI 562, will be presented with a discussion of how these provisions lead to various repair approaches presented to the owner.
Sikalastic One Shot products, Sikalastic-720 One Shot & Sikalastic-726 Balcony One Shot, will be demonstrated. Sikalastic One Shot products are an innovation in traffic coating membranes that replace the need for a base coat and multiple top-coats in a single step. These products re-imagine how traffic coating systems are designed with a polyurethane resin that has both a flexible crack-bridging ability and is extremely durable. Sikalastic-720 One Shot is a one coat system of 45 mils with a proprietary aggregate blend designed for vehicular traffic. Sikalastic-726 Balcony One Shot is a primer-less single step polyurethane system of 35 mils with a proprietary integral texture designed for balconies and pedestrian traffic....
This presentation looks at buildings that are new or being rehabilitated and the impact on making buildings more energy efficient. Starting with the 2012 IBC, and specifically the 2012 IECC portion of the building code and newer versions, the presentation will look at three aspects of the building envelope: Water Resistance, Air Leakage, and Moisture Transmission. It will then compare to identical buildings, the first built in 2000 and the second constructed in 2020. Illustrations and calculations will show how controlling air leakage can have an enormous impact on the service life of the structure, initial cost of construction, and on-going operations. Lastly, the presentation will look at how incorporating simple additions during the repair/rehabilitation process can have a positive impact on the environment as well as the building owner and the building’s constituents.
Increasingly, the Construction Industry is being dramatically impacted globally by internal and external forces. These influences range from acute labor and skill shortages, demographic and urbanization shifts, as well as, the Industry’s conversion from analog-based processes to digital workflows. This presentation will overview ten significant trends which are uniquely affecting the Construction Industry, creating both new challenges and opportunities, while transforming the Construction Industry.
