| 要旨 | Long-term pore structure of fly ash cement paste injected with water through a needle from a 1-mL syringe was investigated, to assess the effects of internal curing on long-term mechanical properties and durability. The injection of water at 1 month to simulate internal curing evidently affected pore structure of cement paste having 40% replacement with fly ash, decreasing volume of capillary pores by 6.0-42.9% up to 24 months and increasing that of gel pores by 10.2-99.2% since 6 months in addition to increasing the consumption of Ca(OH)2 by the pozzolanic reaction by 20.1% at 24 months. |
