Strengthening of the concrete face slabs of dams using sprayable strain-hardening fiber-reinforced cementitious

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 2, Pages 145-160 doi: 10.1007/s11709-022-0806-4

Abstract: slabs in a concrete-face rockfill dam (CFRD) for the first time.It was found that the FRCC layer improved the flexural performance of concrete slabs significantly.The cracking and ultimate loads of a concrete slab with an 80 mm FRCC layer were 132% and 69% higherthan those of the unstrengthened concrete slab, respectively.144% higher than that of the unstrengthened concrete slab.

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).
