Abstract
There are many famous quarries that produced good quality stone in Japan. These stoneworks are produced much stone sludge as by-product. Most of the stone sludge is disposed as wastes, and creating environmental problems. It is necessary to research on methodology for large volume management of stone sludge.Authors have investigated fundamental physical properties of stone sludge for beneficial use. The authors found that the stone sludge can yield much silicate under high-alkaline condition. The Silicate can advance a pozzolanic reaction of cement.This paper describes evaluation of improved soil physical property when stone sludge and cement are mixed with pond sludge. Strength characteristics of the experimental results in uniaxial compression tests and cone penetration test. In addition, the strength development mechanism, field emission scanning electron microscope (hereinafter “FE-SEM” and so on) texture and structure, energy dispersive X-ray spectroscopy (the “EDS” and so on) is described from a quantitative analysis by.
