The invention relates to the technical field of civil engineering materials, and particularly discloses a functional cementing material with a multi-source solid waste synergistic effect and a preparation method of the functional cementing material. The multi-source solid waste synergistic functional cementing material comprises the following raw materials in parts by weight: 60-80 parts of steel slag micropowder, 50-60 parts of slag, 10-20 parts of desulfurized fly ash, 10-15 parts of desulfurized gypsum, 1-3 parts of a water absorbing material and 10-20 parts of an alkali activator. The preparation method has the advantages that the cement stabilized soil can be produced in cooperation with components such as engineering spoil and waste residues, and the cement stabilized soil has the advantages of being high in mechanical strength, good in crack resistance, green and environmentally friendly. 本申请涉及土木工程材料技术领域，具体公开了一种多源固废协同作用的功能型胶凝材料及其制备方法。多源固废协同作用的功能型胶凝材料包括如下重量份数的原料：钢渣微粉60-80份、矿渣50-60份、脱硫灰10-20份、脱硫石膏10-15份、
