Preserving the integrity of cement–bentonite cut-off walls, particularly in aggressive environments, is critical to their serviceability polluted sites. The hardened material walls highly susceptible desiccation and wet–dry cycles, commonly leading cracking. objective work presented this paper was develop crack-resistant wall materials subject cycles. Superabsorbent polymers (SAPs), which are c...

The aim of this study is to investigate how the absorption capacity a superabsorbent polymer (SAP) in cement paste influenced by number variables: type, water-to-cement ratio (w/c), additive, dry SAP particle size, mixing time, and temperature. By means air void analysis hardened paste, specific surface voids are obtained. Parallel direct measurement surface, parameter also derived from size ca...
