ABSTRACT
From this experimental research, it was clear that the crystalline catalyst was effective in improving the durability of the high performance concrete stressed by continuous and repeated mechanical loading. It was confirmed that C-S-H cement crystals are increased in the cracks of the concrete and hence an improved compressive strength and waterproofing which also contributed to understanding the self-healing phenomenon study. In order to systematically design a robust self-healing technology for concrete structures subjected to continuous exposure to water, the use of a Type IS (MS) blast-furnace slag blended cement (25% < slag content <70%) with addition of crystalline catalyst and ductile-type fibers is highly recommended.
