Biomass modified natural marble and preparation method thereof

The invention provides biomass modified natural marble. The biomass modified natural marble is obtained by carbonizing a green body prepared from the following raw materials: 50-70 parts by weight of natural ore slag, 20-30 parts by weight of a filler, 0.5-5 parts by weight of a biomass modifier, 0.5-5 parts by weight of a modifier and 5-10 parts by weight of water. The invention further provides a preparation method of the biomass modified natural marble. According to the biomass modified natural marble provided by the invention, the natural ore slag powder is used as a matrix and is modified by the biomass modifier, so that the reaction efficiency of the biomass modified natural marble and carbon dioxide can be improved, and the filler is used as a filling material, so that the quantity of pore channels into which carbon dioxide gas enters can be increased, the carbonization reaction is promoted, and the aim of dual guarantee of carbonization is fulfilled; the performance of the biomass modified natural mar
