Aged steel slag aggregate marble-imitated base material and preparation method thereof

The invention discloses an aged steel slag aggregate marble-imitated base material and a preparation method of the aged steel slag aggregate marble-imitated base material, and belongs to the technical field of building materials. Comprising the following components: 56-66 parts of steel slag aggregate, 10-16 parts of P.O52.5-grade cement, 6-12 parts of mineral powder, 3-9 parts of steel slag micro powder, 5-8 parts of a superfine reinforced anti-cracking agent, 2.8-4.8 parts of a high-efficiency mineral activator, 0.1-0.3 part of an early-strength polycarboxylic acid water reducing agent and 5-8 parts of water, and the steel slag aggregate is an undersize product obtained by performing steam aging and sieving with the pore diameter of 5mm. According to the invention, the excellent mechanical properties of fracture resistance and compression resistance of a steel slag concrete product are fully combined, and the marble-imitated material prepared by aging the steel slag concrete product is high in strength and
