Abstract
This paper analyzed the co-effects of super absorbent polymer (SAP) and nanomaterials such as silver nanoparticles (AgNPs), graphene oxide (GO) and multiwall carbon nanotubes (MWCNT) in cement pastes. While the SAP cement pastes provided a 25.23% higher 90/28-day compressive strength rate compared to the control sample, the MWCNT- and GO-added-SAP pastes provided a 37.84% and 74.77% higher rate, respectively. GO and MWCNTs increased the 90/28-day ultrasonic pulse velocity rates of SAP cement pastes by 1.25 and 1.38 times, respectively. The cracks initially formed by plastic shrinkage were completely closed with the H-bond ability of MWCNT and GO.
