The invention discloses a high dense two-way adjustable setting concrete and its application. The components and weight of concrete includes: P II 52.5 cement 1, grade II of low calcium fly ash from 0.20 to 0.35, 0.05 to 0.08 portions of silica fume and high performance polycarboxylate admixtures of 0.015 - 0.020, 0.0012 - 0.0020, polypropylene fiber in the sand 2 - 0.32, 5 - 16 stone 1.40 - 1.70, water 0.38 - 0.45, 0 - 0.016 concrete accelerator. The quality indexes of the concrete structure can meet the requirements completely after being sprayed and injected in the base and surface layers. It is suitable for injection molding of concrete structures with high precision and large smooth surface (including concave and convex).
