Designers and inspectors often confuse placement of multiple layers of shotcrete in building out a section with cold joints experienced in cast-in-place concrete construction.
Better Bonding to the Substrate Enhances Durability
Concrete is, by the definition of sustainability, the perfect construction material.
Limestone Cement in Shotcrete
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.
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.

Sustainable Shotcrete Using Blast-Furnace Slag
Two shotcrete mixtures were designed based on sustainability for use in mining ground support.
Material Velocity at the Nozzle
Since the early days of shotcrete, the reduction of rebound has been one of the major technical challenges of the industry due to its obvious impact on material and labor costs and, although less recognized, its detrimental effect on material properties.
