SEBS-Polymer-Modified Slag–Cement–Bentonite for Resilient Slurry Walls

In spite of the well-established design and construction approaches slag–cement–bentonite slurry walls, materials deteriorate inevitably in contaminated land. The development effective which are sustainable, resilient self-healing over lifetime walls becomes essential. This study, for first time, adopts a styrene–ethylene/butylene–styrene (SEBS) polymer to modify enhance mechanical performance. results show that increase SEBS dosage significantly increased strain at failure, indicating enhanced ductility thanks modification by deformable polymer. is beneficial as wall could deform greater extent without cracks. After permeation liquid paraffin, exposed on crack surface swells seals crack, with post-healing permeability only slightly higher than undamaged values, exhibits good Scanning electron microscopy micro-computed tomography analyses innovatively reveal bonding homogeneous distribution slag–cement–bentonite. acts binder protect sample from disintegration, swollen particles effectively seal heal These demonstrate SEBS-modified provide properties
