The introduction of limestone filler in concrete mixtures has received increasing attention from researchers over the last decade.

In the inaugural edition of Shotcrete in February 1999, I had the privilege of writing the first Shotcrete Corner for the magazine.

Can dry-mix shotcrete be air entrained? Is shotcrete not a proven method of pneumatically placing concrete?

At times, safety on construction projects can be challenging. Therefore, it is important to have pretask meetings and proper training prior to starting a job.

Sometimes the significance of the ingredients of shotcrete is overlooked. Water is a good example.

Refractory producers and contractors have a history of trying to put themselves out of business.

The overall process of refractory shotcrete installation is similar to that of commercial and residential concrete installations.

In spite of advancements in cement technology, and research and development efforts on the part of refractory manufactures to develop the ideal gunning mixture, pneumatic placement of refractory castables remains more of an art than an exact science.
