A calcium phosphate cement composition that includes the following two components: A) one or several calcium phosphate powders suspended in an aqueous solution including inhibitor cations inhibiting a reaction of the calcium phosphate powders with water, the inhibitor cations being selected from Mg2+, Sr2+ and Ba2+ at a concentration greater than 0.01 M； and B) an aqueous solution including Ca2+ cations at a concentration greater than 0.1 M. This calcium phosphate cement compositions can be safely stored for years yet still retain its full reactivity when mixed.
