粉煤灰再生集料混凝土的研究

探讨粉煤灰再生集料混凝土的性能。研究表明,利用粉煤灰取代部分再生集料,将显著提高再生集料混凝土的强度,改善表观质量,降低生产成本。建议在利用再生集料制备混凝土时宜掺加合理比例的粉煤灰。

Discussions have been made on property of fly ash reclaimed aggregate concrete.The study shows that the strength of reclaimed aggregate concrete and its apparent mass are improved greatly while the production cost reduces when substitute fly ash for a part of reclaimed aggregate.It is suggested to add reasonable ratio of fly ash when making use of reclaimed aggregate for preparation of concrete.
