The Technical Specification for Production and Application of Red Mud-based Lightweight Soil outlines essential aspects such as -

• production processes
• design principles
• raw material selection
• construction preparation
• mix proportioning
• quality control
• acceptance criteria

This standard applies to various construction and municipal engineering projects requiring load reduction, work on narrow spaces, limited land acquisition, vertical construction, or specific filling needs. It offers comprehensive technical guidance and standardised procedures for using red mud-based lightweight soil across these applications.

The Red Mud-based Cementitious Materials standard defines: -

• performance requirements
• testing methods
• inspection protocols
• packaging
• labelling
• transportation and storage guidelines for these materials

Its release not only facilitates the research, development, and application of red mud-based cementitious materials but also significantly enhances the comprehensive utilisation of red mud, contributing to the advancement of the circular economy.

As a key contributor to the development of these standards, the Guangxi Branch leveraged its technical expertise and extensive experience in the comprehensive utilisation of red mud. The company provided critical technical support and practical insights, actively promoting resource efficiency and fostering the green development of red mud utilisation in China.
