dc.description.abstract | Polysaccharides, and especially alginate, can be useful for self-healing of cracks in concrete. Instead of weak electrostatic bonds present within calcium alginate, covalent bonds, by methacrylation of the polysaccharides, will result in mechanically stronger superabsorbent polymers (SAPs). These methacrylated alginate chains as backbone are combined with two acrylic monomers in a varying molar fraction. These SAPs show a moisture uptake capacity up to 110% their own weight at a relative humidity of 95%, with a negligible hysteresis. The swelling capacity increased (up to 246 times its own weight) with a decreasing acrylic acid/2 acrylamido-2-methylpropane sulfonic acid ratio. The SAPs also showed a thermal stability up to 200 degrees C. Interestingly, the SAP composed of alginate and acrylic acid exerted a very limited decrease in compressive strength (up to 7% with addition of 1 wt% SAP) rendering this material interesting for the envisaged self-healing application. | - |
dc.description.sponsorship | The authors would like to thank the FWO (Research Foundation Flanders) for project funding (3G019012, Effect of tunable hydro gels on concrete microstructure, moisture properties, sealing and self-healing of cracks). The authors would like to acknowledge the group of Peter Adriaensens and especially Gunter Reekmans for the calculation of the degree of methacrylation of algMOD (Organic and Bio-polymer Chemistry Department, UHasselt). | - |
