GCP's award-winning research into rheology control for shotcrete

EVALUATION OF THE USE OF COLLOIDAL SILICA AS A SILICA FUME REPLACEMENT IN WET-MIX SHOTCRETE

The objective of this project was to evaluate the suitability of colloidal silica as a replacement for silica fume in wet-mix shotcrete.

Goin’ Underground: Enhancement of Shotcrete Performance with a Pozzolanic-Based Rheology Control Agent

In underground applications such as mining and tunneling, shotcrete is widely used for structural support of permanent openings, linings, and rock stabilization.

Effect of Pozzolanic-Based Rheology Control Agent on Wet-Mix Shotcrete Performance

The purpose of this article is to present the performance evaluation of wet-mix shotcrete containing a pozzolanic-based rheology control (RC) agent as a replacement for silica fume (SF).

A Case Study on the Impact of Pozzolanic-Based Rheology Control Agent on Wet-Mix Shotcrete Performance in Underground Applications

This paper presents the results of a case study conducted with a major mining operation to assess the impact of pozzolanic-based rheology control agent on the performance of a wet-mix having a specified mix design.

THE USE OF POZZOLANIC-BASED RHEOLOGY CONTROL AGENT IN WET-MIX SHOTCRETE

The objective of this paper is to present the performance evaluation of wet-mix shotcrete incorporating a pozzolanic-based rheology control agent which is a liquid-based product that contains nano-scaled colloidal silica particles with high pozzolanic reactivity.
