Experimental investigation on water retention property of rubble improved by modified hydrophilic polyurethane.

ABSTRACT: Rubble is distributed in discarded spoil sites of engineering construction, mining sites and rocky desertification regions in arid land. Due to the extremely poor water retention capacity of rubble, vegetation restoration proves to be highly challenging in these areas. A type of modified hydrophilic polyurethane material (W-OH), which can effectively improve water retention capacity, shows potential in enhancing the water retention of rubble. In this study, the water desorption and absorption properties of W-OH gel, the influence of temperature on these gels, and the water retention properties and microstructure of rubble improved by W-OH were comprehensively investigated by laboratory tests. The test results showed that the water retention of W-OH gels was dependent on concentration. As t
