Research on the Engineering Properties of Fly Ash as Backfill

Abstract:

The foundation backfill materials with pulverized coal ash and admixture gypsum fly ash were studied. The laboratory experiments were designed to determine its compaction characteristics, compressibility, intensity and bearing capacity of foundation with different mixture ratio. Dry density and strength property of fly ash with different water content were analysed. The result shows that the modulus, strength and foundation bearing capacity all have been greatly improved when gypsum was added into fly ash The proper mix proportion of the gypsum fly ash is very suitable for engineering application and this research provides a scientific reference for the similar projects.
