Recycling superabsorbent polymer solidified spoils as a backfill material

本研究旨在探讨高吸水性聚合物固化土作为回填材料的可行性。水下开挖会产生大量的泥浆弃土。开发了一种使用高吸水性聚合物（SAP）的创新固化技术，可以轻松处理弃土，并在弃土处理和运输方面节省大量资金。然而，由于缺乏支持其用作回填材料的岩土测试数据，这些SAP固化的弃土被处置到倾倒场，并且必须引入工程填充材料来回填地面中的沟槽或孔洞。如果SAP固化弃土可以用作回填材料，将是一个显着的节省。本研究将通过进行一系列的实验室试验来调查岩土工程

This proposed research is to investigate the feasibility of recycling superabsorbent polymer solidified excavation spoils as a backfill material. Excavation conducted underwater generates a significant amount of slurry spoils. An innovative solidification technique using superabsorbent polymer (SAP) has been developed to easily handle the spoils and generated significant savings in spoil handling and transportation. However, these SAP solidified spoils are disposed to dump sites due to lack of geotechnical testing data to support its usage as a backfill material and engineering fill materials have to be brought in to backfill the trenches or holes in the ground. It would be a significant saving if the SAP solidified spoil can be used as a backfill material. This research will address this issue by conducting a series of laboratory tests to investigate the geotechnical
