Application of alkali

Feb 19, 2020One of the most widespread techniques in concrete pavement construction is roller-compacted concrete (RCC) in which Portland cement is used. Recently, an inclination has been seen toward alternative cementitious materials due to environmental concerns expressed over the production of Portland cement. Alkali-activated slag concrete (AASC) has been proposed as a solution to this

Dynamic Analysis of a Roller Compacted Concrete Dam

Field investigations have been completed at the Portugues Dam in Ponce, Puerto Rico. This dam is the first single-centered, roller compacted concrete (RCC), thick arch dam constructed by the U.S. Army Corps of Engineers.
