The Cemented Material Dam: A New, Environmentally Friendly Type of Dam

Jinsheng Jia, Michel Lino, Feng Jin, Cuiying Zheng

Engineering 2016, Volume 2, Issue 4,   Pages 490-497 doi: 10.1016/J.ENG.2016.04.003

Abstract:

The first author proposed the concept of the cemented material dam (CMD) in 2009.This concept was aimed at building an environmentally friendly dam in a safer and more economical wayfor both the dam and the area downstream.The concept covers the cemented sand, gravel, and rock dam (CSGRD), the rockfill concrete (RFC) dam (or the cemented rockfill dam, CRD), and the cemented soil dam (CSD).

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.Health risk assessment was conducted for MSWI fly ash blended cement mortar.strength increases when the fly ash is blended as sand substitute.The k values of fly ash used for sand replacement were all significantly above that used for cement substitution
