Building stone and preparation method thereof

The invention discloses building stone and a preparation method thereof. The building stone is formed in a formwork pouring mode and used for simulating formed natural stone. The building stone is prepared from cementing materials, aggregate, fibers, polymer emulsion, additives and water. The cementing materials comprise cement and fine active mineral materials. The building stone is obtained through the construction processes of raw material mixing, stirring, forming, curing and the like. The building stone has the unique appearance and texture of natural stone; demoulding can be performed immediately after forming, and therefore the mould utilization rate can be greatly increased; the raw materials in use are easy to purchase, the cost is lower than that of natural stone, and the requirements for environmental protection, energy saving and consumption reduction are met.
