COMPOSITION AND MANUFACTURING METHOD OF HIGHLY DURABLE GROUTING MATERIALS COMPRISING GEOPOLYMERIC QUICK SETTING MATERIAL FOR WATER BLOCKING AND SOIL STRENGTHENING

摘要

PURPOSE: A grouting material composition for water blocking and soil strengthening is provided to obtain a two-part environment-friendly grouting material composition with high strength and excellent durability. CONSTITUTION: A method for preparing a grouting material composition consisting of A liquid which is a geopolymeric quick setting material, and B liquid which is cement-based suspension comprises the steps of: preparing A1 liquid using powder consisting of pozolane materials, fluidifier and quick setting material; mixing A1 liquid with A2 liquid consisting of at least one material selected from liquid alkali silicate salt and silica sol to prepare the A liquid; and mixing powder with water to prepare the B liquid as a strength developer, wherein the powder includes cement, alkaline salt powder as a quick setting material and cement fluidifier.
