Abstract

Water-swelling material is a fluid sealant obtained by blending high absorbency polymer, a filler and a solvent by using a synthetic resin elastomer as the base material. In this research, we have studied the composition of water-swelling material, the extent of swelling, strength of the water swelling-material and the long-term performance of swelling material used as jointed water cut-off treatment material at waste landfill sites, by conducting various experiments. One of the examples of the results is that the adjustment of the degree of etherification of high absorbency polymer which is a component of the water-swelling material and the resin content of the synthetic elastomer contribute to the improvement of swelling of the sealant and strength of the swelling material. Further, as time passes, the strength of the water-swelling material shows a tendency to become stabilized and it was confirmed that it had sufficient pressure-resistance in coastal landfill sites, where its application as water cut-off treatment material is being considered.
