Název v původním jazyce
Self-Healing Capability of Cement Paste Modified by Blast Furnace Slag and Superabsorbent Polymer
Popis výsledku v původním jazyce
Building materials based on cement composites are prone to crack propagation and consequent material deterioration. The crack propagation in concrete structures is subjected to long-term investigation in order to mitigate this undesired phenomenon since it requires substantial costs to prolong the service life of constructions. In this study, the self-healing capability of cement paste induced by blast furnace slag and superabsorbent polymers is investigated. Precracked specimens with selected dosages of both admixtures are studied in terms of the cracks width development over time. The water flow experiment was employed to access the crack closing and complete the data delivered by optical microscopy. The obtained results indicate that utilization of superabsorbent polymers in combination with furnace slag has a synergic effect on crack sealing. In the most positive case, the crack was sealed off about 57 % after 56 days for 40 % replacement of Portland cement by GBFS and 0.5% dosage of SAP.
