1. An aqueous composition comprising an aqueous solution, a silicate compound, α-TCP and a phosphorylated amino acid;
wherein the amount of phosphorylated amino acid is 20-50 wt % of the solid content, the combined amount of silicate compound and α-TCP is 10-80 wt % of the solid content, wherein the weight ratio of the silicate compound to α-TCP is 1:1-50; wherein the silicate compound is a mixture of di- and tricalcium silicate; and wherein the composition has a shear strength to bone of at least 1.5 MPa when measured after 24 h of curing at 100% humidity and 37 C.
