Portland cement type I (PC, Quikrete® Number 1124, Atlanta, GA, USA)
(a) Distilled water “W,” provided by manufacturers. (b) Experimental liquid “H.” 0.3 g calcium chloride dihydrate (CaCl2⋅2H2O) + 0.075 g fumed silica (Aerosil EG 50, Evonik) + 0.3 g hydroxyapatite [Ca10(PO4)6(OH)2] + 1 ml distilled water. (c) Experimental liquid “P,” similar to “H” except that the 0.3 g hydroxyapatite was replaced by 0.3 g calcium hydrogen phosphate.
