Field Trials Validate Safecrete Technology for Oyu Tolgoi

December 1, 2025

Safecrete Technology successfully completed field trials using Oyu Tolgoi batch mix designs at the Sika Mongolia office, validating the headings management system's accuracy for one of the world's largest copper mining operations.

The week-long validation programme included shotcrete handspraying trials using Oyu Tolgoi's actual batch mix designs and materials, testing multiple formulations with varying silica fume and accelerator dosages to validate Safecrete's maturity method technology.

Demonstrating 95%+ R² correlation accuracy to operational teams and senior leadership — including General Managers of underground and surface operations — the trials confirmed Safecrete's technology delivers reliable strength predictions for world-class mining applications.

Field Validation for Tier-One Mining

Demonstrating technology accuracy for world-class mining operations requires rigorous field trials using actual mine materials and operational parameters to validate monitoring capabilities.

Validation Requirements

Tier-one mining operations demand proven technology accuracy using their specific batch mix designs, materials, and operational parameters before deployment.
Maturity method calibration requires testing across multiple formulation variables to ensure prediction reliability under diverse shotcrete specifications.
Statistical validation with R² > 0.90 correlation provides confidence that monitoring technology delivers operationally useful strength predictions.

Successful Field Trials

Week-long handspraying programme tested multiple shotcrete panels with varying silica fume and accelerator dosages using Oyu Tolgoi batch mix designs.
Achieved exceptional 95%+ R² correlation between predicted and measured strengths, exceeding industry standards for maturity method accuracy.
Demonstrated technology validity directly to operational teams and senior leadership, establishing confidence for potential large-scale deployment.

Field Trial Programme

Shotcrete Handspraying Trials

Sika facilitated a week-long field trial programme at their Mongolia office using Oyu Tolgoi's actual batch mix designs and site materials. Multiple shotcrete panels were handsprayed with systematically varied silica fume content and accelerator dosages to test the maturity method across diverse formulation parameters. Each panel was continuously monitored with Safecrete's temperature sensors throughout the curing process, whilst physical strength testing provided ground truth data for calibrating maturity curves and validating prediction accuracy.

Exceptional Validation Results

The trials achieved 95%+ R² correlation between predicted and measured uniaxial compressive strengths, demonstrating that Safecrete's maturity method delivers exceptional accuracy for Oyu Tolgoi's specific materials and formulations. This level of statistical correlation, validated in real field conditions rather than laboratory environments, confirms the technology's reliability for operational deployment. The results were presented directly to operational teams and senior leadership, providing tangible evidence of monitoring value for underground development and surface construction applications.

Sika Partnership Enablement

Sika's facilitation extended beyond market introductions to hands-on trial support, providing technical expertise, site access, and material coordination throughout the validation programme. This partnership approach demonstrates how collaboration between technology providers and established industry suppliers creates mutual value — Safecrete gains validated accuracy for a world-class operation, whilst Sika delivers enhanced monitoring capabilities to strategic customers. The successful trials position both companies to serve Oyu Tolgoi with integrated shotcrete supply and monitoring solutions.

Partnership Appreciation

Safecrete extends sincere appreciation to Sika for facilitating this significant engagement opportunity and opening doors to world-class mining operations through their trusted global relationships.

The partnership demonstrates how strategic collaboration between technology providers and established industry suppliers creates mutual value and accelerates market adoption of innovative monitoring solutions.
