    摘要: Calcium phosphate particles having A) a specific surface area (SSA) larger than 0.1 m2/g; B) a mean diameter smaller than 5 mm; C) a Ca/P molar ratio superior to 0.95; and wherein D) said particles have been subjected as a last processing step to a heat treatment at a temperature superior to 400° C. for a period of time such that the specific surface area (SSA) of said particles after the heat treatment is not decreased by more than 10% compared to the SSA before said heat treatment.

    摘要: A construction composition includes: an ash in an amount of 90.0-99.9 wt. %, based on the total weight of the construction composition, wherein the ash is fly ash or bottom ash; an additive composition in an amount of 0.1-10.0 wt. %, based on the total weight of the construction composition, wherein the additive composition includes a component from group (2a) and a component from group (2b), wherein group (2a) consists of metal chlorides and wherein group (2b) consists of silica, zeolite and apatite, and wherein group (2a) includes 70.0-99.0 wt. % of the total additive composition and group (2b) comprises 1.0-30.0 wt. % of the total additive composition; and cement, in an amount of 0.0-5.0 wt. %, based on the total weight of the construction composition. With this composition, fly ash can be used as construction material, having properties comparable or better than concrete.
