Key Findings

01Mudstone and slag can be synthesized into viable geopolymers for waterproof composites.
02MSWCs meet the requirements for reconstituted water barriers, with permeability suitable for application.
03Increasing the mudstone proportion in MSWCs leads to decreased permeability and uniaxial compressive strength.
04The optimal mudstone proportion for balancing compressive strength and permeability was found to be 0.6.
05Cyclic loading and unloading initially increased MSWC compressive strength but then decreased it, while also increasing microfractures and permeability, reducing waterproofness.
