“…It is known that the structure of ettringite is based on two distinct structural components 5) ; columns of {Ca 6 [(Al,Fe)(OH) 6 ] 2 · 24H 2 O} 6ϩ and channels of {(SO 4 ) 3 · 2H 2 O} 6Ϫ which contain four sites, of which three are occupied by sulfate and one by two water molecules. With this structure a modest deviation in composition can be tolerated without causing a change in structure.…”

“…Most of the crystal structure models used in this study were taken from published data. [33][34][35][36] In general, the refinement proceeded in steps where diffraction patterns of selective extractions of the cements were refined and the structural and peak shape profile parameters were established. These parameters were subsequently fixed to avoid correlation problems in the more complex mixtures.…”

“…The present analysis uses the comprehensive experimental results from the U.S. Bureau of Reclamation research on sulfate resistance of concrete (4). Concrete cylinders measuring 76 ϫ 152 mm were cast with stainless-steel gauge studs inserted into the ends of the cylinder to establish a gauge length of 127 mm.…”

“…For Ͼ40 years until 1991, the U.S. Bureau of Reclamation collected data of concrete expansion due to sulfate attack (4)(5)(6)(7). A wide range of concrete mixture proportions were selected to determine the effect of water-to-cement ratio, cement composition and fineness, curing temperature, and admixtures on the expansion of cylinders exposed to realistic conditions.…”
