Utilization of MSWI fly ash as partial cement or sand substitute with focus on cementing efficiency and

Lei Zheng, Xingbao Gao, Wei Wang, Zifu Li, Lingling Zhang, Shikun Cheng

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 1, doi: 10.1007/s11783-019-1184-6

Abstract: Washed MSWI fly ash was used as partial cement or sand substitute.Sand replacing is beneficial for strength, while cement replacement reduces strength.replacement ratio was 0.75%.The k values of fly ash used for sand replacement were all significantly above that used for cement substitutionThe macropores assigned to the gaps between particles decreased when the fly ash was used as sand replacement

Effects of coarse and fine aggregates on long-term mechanical properties of sea sand recycled aggregate

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 754-772 doi: 10.1007/s11709-021-0711-2

Abstract: Typical effects of coarse and fine aggregates on the long-term properties of sea sand recycled aggregateTwo different types of fine (coarse) aggregates are considered: sea sand and river sand (natural andresults show that the compressive strength of SSRAC increase with decreasing recycled coarse aggregate replacementpercentage and increasing sea sand chloride ion content.however, the deformation differences between coarse aggregate and cement mortar reduce by adopting sea sand
