Some concrete projects across Arkansas are cracking because of high-alkali cement that was used from 1997 through 2002, according to researchers at the University of Arkansas at Fayetteville. The ...
When bridges, dam walls and other structures made of concrete are streaked with dark cracks after a few decades, the culprit is AAR: the alkali-aggregate reaction. AAR damages concrete structures all ...
Summary: The focus of this project is to model the shear strength of concrete panels that have experienced alkali silica reaction. The end goal is to be able to derive an equation that relates the ...
Fly ash generated by coal-fired power stations is an environmental headache, creating groundwater and air pollution from vast landfills and ash dams. Some of the waste product can be repurposed into ...
