Anti-freezing hydraulic concrete and production process thereof
The invention relates to the technical field of building materials, in particular to anti-freezing hydraulic concrete and a production process thereof. The anti-freezing hydraulic concrete is prepared from the following raw materials in parts by weight: 300-380 parts of cement, 850-1000 parts of coarse aggregate, 600-700 parts of fine aggregate, 60-80 parts of mineral powder, 50-65 parts of fly ash, 15-20 parts of calcium formate, 6-10 parts of an anti-freezing enhancer, 3-5 parts of a synergistic anti-freezing agent, 6-10 parts of a water reducing agent, 5-8 parts of an air entraining agent and 170-200 parts of water, under the synergistic action of the anti-freezing reinforcing agent and the synergistic anti-freezing agent, the concrete produced by the invention not only has excellent anti-freezing performance, but also has excellent mechanical properties, and the quality of the concrete is effectively ensured.
本发明涉及建材技术领域，具体为一种抗冻型水工混凝土及其生产工艺；所述抗冻型水工混凝土由以下重量份原料组成：300～380份水泥、850～1000份粗骨料、600～700份细骨料、60～80份矿粉、50～65份粉煤灰、15～20份甲酸钙、6～10份抗冻增强剂、3～5份协效抗冻剂、6～10份减水剂、5～8份引气剂及170～200份水；在抗冻增强剂及协效抗冻剂的协同配合作用下使得本发明所生产的混凝土不仅具有优良的抗冻性能，还具有优良的力学性能，有效地保证了混凝土的品质与质量。
