粉煤灰水泥早期水化的原位观察
In-situ Observation of Hydration of Fly Ash Cement at Early Age
摘要
Abstract
The fly ash cement compact with the size of 35 mm × 25 mm × 25 mm was prepared.The early hydration of fly ash cement compact in situ was investigated by laser scanning confocal microscopy (LSCM).The results show that LSCM is helpful in in-situ investigating the hydration and the pore evolution of fly ash cement compact.Hydration products are formed around cement particles when fly ash cement compact contacted with water for 8 h.With increasing hydration time,the quantity of hydration products increases,most of the space between cement particles and fly ash particles is filled by hydration products.After 3 d hydration,the microstructure of hydrated compact become denser,and the microstructure evolution of the fly ash cement compact slows down.关键词
