The invention discloses a high-strength concrete formula production process. The concrete is prepared from, by weight, 17-22 parts of cement, 21-31 parts of sand, 20-35 parts of stone raw materials, 15-25 parts of mineral admixtures, 4-10 parts of steel fibers and 13-17 parts of water. The beneficial effects of the high-strength concrete formula production process are that: by adopting the sand with low water content, the raw material ratio of the concrete during stirring can be more accurate; by using the clean dust-free cubic broken stone with the rough surface and the edges, the right-angled mixing effect of the stone raw material and other materials can be better; the mineral admixture can be slowly hydrated in the presence of water and lime; a cementitious substance of increased strength is generated to fill pores in the concrete, and the silicon powder and the zeolite powder are of amorphous and compact structures, so that the microstructure of a two-phase interface area is obviously improved, the strength, the impermeability and the durability of the concrete can be improved, and the silicon powder can enable the concrete to have very good workability and stability.
本发明公开了一种高强度混凝土配方生产工艺，包括原料的组成：水泥17‑22份、砂21‑31份、石原材料20‑35份、矿物掺合料15‑25份、钢纤维4‑10份和水13‑17份，本发明的有益效果是：本发明通过采用含水量低的砂可以使得混凝土在搅拌时的原料比更加精准，通过使用表面粗糙且干净无粉尘带有棱角的立方碎石能够使得石原材料与其它材料直角的混合效果更好，矿物掺合料在有水和石灰的条件下会缓慢水化，生成增加强度的胶凝物质，充填混凝土中的孔隙，硅粉和沸石粉呈无定形的、致密结构，从而明显地改善了两相界面区的微结构，可以提高混凝土的强度、抗渗性及耐久性能，硅粉可以使得混凝土具有很好的合易性和稳定性。
