Durability Investigation of Ultra-Rapid Strength-Gain Dry-Mix Shotcrete
It has already been shown that rapid strengthgain dry-mix shotcrete using calcium sulfoaluminate (CSA) cement and providing about 2900 psi (20 MPa) after only 2 hours can be effectively produced and placed in mining applications (Reny and Clements 2013).
Evaluating Ready Mix Suppliers
Oscar Duckworth has covered the keys of the equipment necessary for successful wet-mix shotcrete in the past few ?Nozzleman Know ledge? articles. This article discusses the importance of the material supplier in the equation.
The Hidden Danger of Noise
Shotcrete workers are subject to noise, much of which is at potentially dangerous decibel levels.
The Durability of Shotcrete? Looking Back at Projects from 30 to 40 Years Ago
Anyone who has ever had to remove old gunite from a bridge or an overpass knows how incredibly difficult it can be to tear out.
A Closer Look at the Benefits of Predampening
Much has been written on the benefits of predampening dry-mix shotcrete (gunite) materials before application; however, it is worth exploring these benefits in greater detail.
