506.4R-19 Guide for the Evaluation of Shotcrete

Abstract:

This document provides information on the evaluation of both dry-mix and wet-mix shotcrete. It is assumed throughout the document that shotcrete is a method of placing concrete. However, for the sake of readability, the word “shotcrete” is often used either to identify the shotcrete process (method) or the shotcrete mixture (product) in the present document. Evaluation of in-place shotcrete requires experience, education, and engineering judgment. This document serves as a guide for engineers, inspectors, contractors, and others involved in accepting, rejecting, or evaluating in-place dry- or wet-mix shotcrete.
