CONSTRUCTION OF A BARRIER LAYER HAVING EXCELLENT SELF-SEALING AND SELF-HEALING PROPERTIES IN ORGANIC WASTES-RECLAIMED LANDS VIA POZZOLANIC REACTION

摘要

PURPOSE: A method for constructing a complex barrier on a fundamental ground of waste reclaiming place is provided by which the constructed complex barrier has a good strength property, water permeability and is able to excellently self-from and self-recover. CONSTITUTION: A method for constructing a complex barrier comprises steps of: (i) inoculating microbial fungus on soil for constructing barrier to prevent the contact between soil particle and cement mineral and disintegrate humic acid, which inhibits pozzolanic reaction between the soil particle and cement mineral to bond together and solidify, in a short time; (ii) mixing solidifying materials causing pozzolanic reaction with the treated soil of step (i) to obtain the solidified soil; (iii) multi-layering the obtained solidified soil on the place where the barrier is installed; and (iv) treating the outer layer and then curing it.
