Abstract
This study had propose that a characteristic of recently developed Silicasol to make a close in this study, grouting material usually used portland cement and a characteristic is compared between Silicasol and sodium silicate in this study, examined strength and environmentally friendly for compare characteristics of sodium silicate and Silicasol through unconfined compressive strength, SEM analysis, Permeability test, Chemical Resistance test, leaching test etc. In the test, I gained that unconfined compressive strength of Silicasol three times promoted than sodium silicate Within 72 hours and I gined through analysis of SEM that Silicasol is more compactivetive than sodium silicate. In the result of test, it was found to be a environmentally friendly material as the toatal amount of eluviated elementary had small quantity.
