USE OF PHOSPHOGYPSUM IN ROADBASES
| 项目名称： | USE OF PHOSPHOGYPSUM IN ROADBASES |
| 摘要： | THIS RESEARCH IS IN THREE PARTS: (1) STUDY OF THE ACTIVATION OF GRANULATED SLAG BY MEANS OF PHOSPHOGYPSUM AND OTHER AGENTS; (2) DEVELOPMENT OF OPTIMUM FORMULAE FOR GRAVEL-SAND MIXTURES STABILIZED WITH SLAG USING MAXIMUM QUANTITIES OF PHOSPHOGYPSUM; (3) DEVELOPMENT OF A BINDER CONTAINING SLAG AND PHOSPHOGYPSUM AND STUDY OF THE POSSIBILITY OF USING THIS BINDER FOR STABILIZING GRAVEL AND SAND AND FOR USING IN CONCRETE. IN 1979 IT IS PLANNED TO CONTINUE THE STUDIES STARTED IN 1978: - TO ESTABLISH A GRAVEL AND SAND-SLAG- PHOSPHOGYPSUM-SODIUM FORMULA WITH A HIGH PHOSPHOGYPSUM CONTENT; - TO ESTABLISH A FORMULA FOR PHOSPHOGYPSUM STABILIZED WITH SLAG; - TO ESTABLISH A FORMULA FOR FLY-ASH-LIME-PHOSPHOGYPSUM WITH A HIGH PHOSPHOGYPSUM CONTENT; - TO ESTABLISH A FORMULA FOR GRAVEL-FLY ASH PHOSPHOGYPSUM. STUDIES WILL ALSO BE INITIATED ON: - THE USE OF PHOSPHOGYPSUM AS CORRECTOR IN GRAVEL-CEMENT; THE OPTIMIZATION OF THE MIX DESIGN OF - ROAD CONCRETE CONTAINING PHOSPHOCEMENT (SHRINKAGE - CRACKING); - PROPORTIONING OF PHOSPHOGYPSUM SLAG AND FLY-ASH BY MEANS OF RADIOACTIVITY. THIS RESEARCH PROJECT SUPERSEDES IRRD RESEARCH PROJECTS NOS 500597 AND 500599. |
