A Brief Review of Rock-Filled Concrete Dams and Prospects for Next-Generation Concrete Dam Construction Review

Feng Jin, Duruo Huang, Michel Lino, Hu Zhou

Engineering 2024, Volume 32, Issue 1,   Pages 100-106 doi: 10.1016/j.eng.2023.09.020

Abstract:

Over the past few decades, one of the most significant advances in dam construction has been the inventionof the rock-filled concrete (RFC) dam, which is constructed by pouring high-performance selfcompactingconcrete (HSCC) to fill the voids in preplaced large rocks.  The innovative use of large rocks in dam construction provides engineers with a material thatrequires less cement consumption and hydration heat while enhancing construction efficiency and environmental
