Summary: | 碩士 === 國立交通大學 === 土木工程系所 === 95 === Good cure, have is the key to concrete performance, such as durability, strength, water-tightness, volume stability, etc. High hydrateion of Portland cement will reduce voids pores and crack of inner concrete and make the strength higher. The mineral admixtures for SCC(Pozzolanic materials) hydrate in later stage. If there is not enough water, then pozzolanic reaction will not be activated, and the characteristics will not be improved.
This study investigates the effectiveness of the self-curing material. There are four self-curing materials, namely A, B, C, and D. There is no need to cure the concrete after pouring. The material A, B, C and D can absorb water from the air and then release to concrete. The material A, B, C are in liquid state, and material D is powder. The water loss, volume change, and mechanical properties were studied.
