Enhanced durability performance of cracked and uncracked concrete by means of smart in-house developed superabsorbent polymers with alkali-stable and -unstable crosslinkers

For the past two decades, research on use of superabsorbent polymers (SAPs) in cementitious materials has proven that these innovative have potential to become a suitable admixture concrete industry. Not until recently, most applications studied made SAPs originally designed be used other industries, such as food, agricultural and hygiene products. In this paper, an “in-house” developed SAP (SAPX) is presented, with double crosslinking system specifically for structures. Its efficiency compared commercially available (SAP1 SAP2) different applications. The promoted immediate sealing effect cracked specimens reflected by reduction 72% water permeability cracks up 250 µm without SAPs. A superior performance was also found against frost attack salt scaling after 28 cycles freezing thawing. Although no complete mitigation shrinkage noticed, SAPX significant strain at early ages days. terms mechanical properties, reduced strength comparable extent SAP1 less than SAP2. To conclude, showed better already commercialized high towards large-scale production exploited
