Today, the use of supplemental cementitious material (SCM) (fly ash, microsilica, or slag) with portland cement is commonplace.
The Use of Recycled Glass in Shotcrete
Right after the G8 summit in Japan 2008, the International Energy Agency was mandated to work on the development of technology roadmaps meant to identify specific industries and help governments in their quest for sustainable development.
Where Are We Now with Sprayed Concrete Lining in Tunnels?
Traditional methods of sprayed concrete lining (SCL) tunnels (in soft ground) comprise a temporary primary lining of sprayed concrete with a sheet membrane inside and a permanent cast in-situ concrete lining, usually reinforced with steel bars
Volumetric Batching of Wet-Mix Shotcrete
For decades, volumetric batching has been commonplace in the dry-mix shotcrete process.
Dry-Mix Equipment Maintenance
Maintaining your dry-mix shotcrete (gunite) equipment ensures that your crew will get the most efficient production, maximum service life, and safest operation from your machinery and accessories.
Success in Shotcreting Begins with Forming
In the creation of swimming pools, forming is one of the core components to building a successful shotcrete structure, and can be done in a variety of ways.

Reaching 20 MPa (2900 psi) in 2 Hours is Possible
In the mining and tunneling industries, time is critical; and as the mining/tunneling cycle becomes shorter, production increases.
Sustainable Shotcrete Using Blast-Furnace Slag
Two shotcrete mixtures were designed based on sustainability for use in mining ground support.
