The use of structural shotcrete in lieu of ?form-andpour? is growing rapidly in the urban concrete building construction and civil infrastructure sectors throughout North America.
The History of Shotcrete Equipment
Transcrete specialized in building pumps for highrise buildings and large concrete placements. The concrete used on these projects was normally low-slump, high-strength mixtures.
ACI Nozzleman Certification – Why, Who, When, and How
ASA is the largest ACI sponsoring group offering ACI Shotcrete Nozzleman Certification in the world.
Overhead Shooting against PVC Membrane
Overhead shotcrete application against any substrate is challenging. Shooting against a polyvinyl chloride (PVC) membrane waterproofing system increases the difficulty and danger of the process.
Tips for Maintaining High- and Low-Pressure Concrete Pumps
Cleaning and maintenance is one of those ?necessary evils.? It takes time away from shotcrete placement on the project but skipping it can be even moretime consuming, as well as costly.
Responding to an OSHA Inspection
Whether an OSHA inspection of your workplace or construction site is triggered by a workplace injury, a formal complaint, a programmed wallto- wall inspection, or just a spot decision while OSHA happens to drive by your construction site, being preparedbeforehand will help limit exposure and help defend against any citations that may be issued.
Shotcreting the East Side Access Program
Prior to 9/11, all structural wall and tunnel concrete applications in New York, NY, used the form-and-pour concrete placement method.
Shotcrete Lining Innovations in the United States
Historically, the permanent concrete linings for underground structures have been installed using form-and-pour methods but the use of shotcrete or sprayed concrete for the structural linings is becoming increasingly more common.
Chemistry and Heat Treatment
If you stop and take a look around your shop at your equipment and tools, and maybe the walls and beams of the building itself, you are bound to see dozens or hundreds of individual metal components.
Can Supplemental Consolidation Extend the Limits of Shotcrete Placement
In many major metropolitan regions of the United States, shotcrete methods are being used daily to place concrete within elements incorporating large, highly congested reinforcement layouts.
