| Abstract: | Abstract The civil research community has been attracted to concrete with self-healing properties since they are an intelligent solution for sustainable infrastructures with long duration. The present study is analyzing the self- healing capability of early age and structural cracks in concrete by using crystalline admixture as self-healing agent under four different exposure conditions by assessing the regained mechanical properties of concrete. Physical (morphological) and chemical composition of the hardened pastes, were studied using Fourier transform infrared spectroscopy (FTIR) and energy-dispersive spectroscopy (EDS). The analysis showed that for all exposure conditions the compressive strength and split tensile strength of the tested concrete with crystalline admixture (CCA) samples regains after early age and structural cracks. This is due to substantial increase in the calcite content which is evident from SEM-EDS and FTIR analysis. [ABSTRACT FROM AUTHOR] |
