URETHANE-BASED COMPOSITION FOR BLOCKING WATER AND STRENGTHENING SOIL HAVING EXCELLENT COMPRESSIVE STRENGTH AND BENDING STRENGTH

摘要

PURPOSE: A urethane-based composition is provided to more effectively strengthening soil, and to have strong water-blocking effect by respectively maintaining compressive strength and bending strength over 400 and 500.;CONSTITUTION: A urethane-based composition comprises an A liquid in which polyol with hydroxyl group, a catalyst, and a surfactant are mixed, and a B liquid comprising a compound with an isocyanate group. The viscosity of the polyol is 50-60 cps. The hydroxyl group satisfies range of 500-600, and is a compound of polyoxyalkylene glycol, polyetherpolyols, or divalent alcohol polymer. The catalyst is tetramethylhexane diamine, and the surfactant is a silicon surfactant.;COPYRIGHT KIPO 2012
