Calcined bauxite (CB) aggregate has been reported to be a porous aggregate and provide IC effect in non-fibrous UHPC matrix, and the effect of different dosage of CB aggregate on the IC efficiency has been studied [14], [15].CB is produced from raw bauxites (one type of laterite rocks) sintered at high temperatures (above 1000 °C).

In 1976, the use of Calcined Bauxite (CB) in HFST showed significant crash reductions of 31% for 800 intersections in London [6, 8]. Calcined Bauxite is the most common aggregate used in HFST [11–14]. Currently, Calcined Bauxite is the primary aggregate used for HFST in Missouri [12–14].
