The invention provides a construction composition comprising: 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 comprises 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) comprises 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. |
