WebOct 8, 2024 · Abstract. The scope of the present paper is to understand the effects of crystalline admixture on the self-healing capacity of the cementitious composites. Previous studies were examined and a conclusion was drawn to the effect that different additives to crystalline admixture tend to improve self-healing of concrete for larger cracks. WebThe crack healing capacity of the material was limited: the maximum crack size capable for self-healing of the ceramic material was 2c = 250–300 μm and w = 0.68 μm, and the corresponding healing condition was of 800 °C/60 min. (2) The crack healing in Al 2 O 3 /SiC w /TiSi 2 ceramic was primarily caused by the oxidation reaction of Ti 5 Si ...
