WebCommon recycled or supplemental cementitious materials (SCM) are slag, a byproduct of the steel industry, and fly ash, a byproduct of coal combustion. Using varying quantities of fly ash can result in different hues, ranging from buff to brown. Slag use may produce an initial slight bluish or green tint that lightens with time. WebThe creep of concrete containing fly ash was found to be less than or equal to that of portland cement concrete when subjected to equal sustained loads, even though the 28 …
