T/WHCIA 1004-2023 Modification of gypsum-based filling material application technical specification
Abstract
Main technical content: This standard relies on relevant actual projects to explore new utilization paths for the comprehensive utilization of phosphogypsum, enabling the modified phosphogypsum to be used for engineering backfilling according to established procedures, and effectively improving the comprehensive utilization rate of industrial solid waste phosphogypsum. It was proposed by China Construction Third Engineering Division Co., Ltd. and China University of Geosciences (Wuhan), and is divided into 6 chapters and 3 appendices. The main contents include: General Principles, Terminology, Performance of Backfilling Materials, Design Selection, Preparation and Construction of Mixes, Quality Inspection and Acceptance, etc.
