Continuous strengthening type combined gel system concrete anti-corrosion material in heavy salinized soil environment
The invention relates to a continuous strengthening type combined gel system concrete anti-corrosion material in a heavy salinized soil environment. The continuous strengthening type combined gel system concrete anti-corrosion material comprises the following materials in parts by weight: 100 parts of a gel material, 350-400 parts of an aggregate system and 30-40 parts of water, 0.2 part of fiber and 0.8-2.0 parts of a water reducing agent; wherein the cementing material is prepared from the following components in parts by weight: 55 to 66 parts of ordinary Portland cement (low alkali), 15 to 20 parts of F-type fly ash, 10 to 15 parts of S95 mineral powder, 8 to 10 parts of CEA-Z magnesium concrete corrosion-resistant enhancer and 1 to 2 parts of nano SiO2; wherein the aggregate system is prepared from the following components in parts by weight: 150 to 200 parts of medium sand and 200 to 250 parts of 5 to 25 graded broken stone. The gelling system concrete anti-corrosion material has the compressive strength of 40-55 MPa, low porosity and good volume stability, can ensure good volume stability and compactness in the early age, has the sulfate dry-wet cycle resistance 4 times or more higher than that of common concrete, and is especially suitable for concrete building structures with moderate strength requirements in a heavy salinized soil environment area.
一种重盐渍土环境下续强型组合胶凝体系混凝土抗蚀材料，其组成包括以下重量份数的物料：胶凝材料100份，骨料体系350‑400份，水30‑40份；纤维量0.2份，减水剂0.8‑2.0份；其中，所述胶凝材料包括以下重量份数的组分：普通硅酸盐水泥(低碱)55‑66份，F类粉煤灰15‑20份，S95矿粉10‑15份，CEA‑Z镁质混凝土抗蚀增强剂8‑10份，纳米SiO21‑2份；其中，所述骨料体系包括以下重量份数的组分：中砂150‑200份，5‑25级配碎石200‑250份。本发明的胶凝体系混凝土抗蚀材料，抗压强度在40MPa‑55MPa，孔隙率低，体积稳定性好，能保证早龄期良好的体积稳定性和密实性，比普通混凝土耐硫酸盐干湿循环能力高4倍以上，特别适用于重盐渍土环境区中等强度要求的混凝土建筑结构。
