In life, learning from practical experiences often requires learning from our misunderstandings and mistakes.
ACI Committee 506, Shotcreting? Activities Update
ACI Committee 506, Shotcreting, is one of the most active technical committees of the American Concrete Institute (ACI).
Guide to Shotcrete
In 1910, naturalist Carl Akeley introduced a machine he invented to build mortar models of animals at the cement show in New York.
Comparative Evaluation of Transport Properties of Shotcrete Compared to Cast-in-Place Concrete
The question is sometimes asked: ?How does the durability of shotcrete compare to that of cast-in-place concrete?? The durability of shotcrete and concrete structures is strongly influenced by their transport properties.
The Use of Slag Cement, Alkali-Free Accelerator, and Macro-Synthetic Fibers
This paper presents the results of a case study conducted in a wet-mix shotcrete application of a major tunnel construction located in Sydney, Australia.
Reinforcing Bar Shadowing and What You Can Do
Nearly all shotcrete projects I come across in my travels consist of some form of steel reinforcement, such as reinforcing bars or welded wire reinforcement.
An Approach for Improving the Sustainability of Shotcrete
According to the World Commission on Environment and Development,1 sustainability is defined as ?meeting the needs of the present without compromising the ability of futuregenerations to meet their own needs.?
Traffic Construction Safety
To work safely in and around heavy traffic there are many things to be concerned about.
Cold-Weather Shotcreting
The dry-shotcrete process has a long history with placing concrete pneumatically for over 105 years.
Changing a Culture Takes Time
Changing a culture takes time. Missouri?s reputation as a ?Show Me? state stands true as MoDOT engineers had to be shown that shotcrete is a viable solution before they openedup their specifications.
