Preparation method and use method of anti-abrasion concrete admixture in freeze-thaw-corrosion environment
The invention discloses a preparation method and a use method of an anti-abrasion concrete admixture under a freeze thawing-corrosion environment, and the admixture comprises the following components in parts by weight: 50-60 parts of STG powder, 5-8 parts of polyimide fiber, 1-3 parts of hydroxypropyl methyl (HPMC) cellulose, 10-13 parts of a polycarboxylate superplasticizer, 10-15 parts of an anti-freezing agent and 10-13 parts of an expanding agent. Wherein the STG powder comprises modified silica fume-glass powder, titanium silicon carbide and graphene oxide. The anti-abrasion concrete admixture under the freeze-thaw-corrosion environment can effectively inhibit decomposition of calcium hydroxide, can refine a pore structure, enables hydraulic concrete to be more compact, improves corrosion resistance of the hydraulic concrete, enhances anti-abrasion performance of the hydraulic concrete, has good low-temperature resistance, and is suitable for being used in the field of hydraulic engineering. The material can be suitable for a cold low-temperature environment, and the anti-abrasion strength under the low-temperature condition is obviously improved.
本发明公开了一种冻融‑溶蚀环境下抗冲磨混凝土外加剂的制备方法和使用方法，所述外加剂包括以下重量份数的各组分：50～60份STG粉末，5～8份聚酰亚胺纤维，1～3份羟丙基甲基(HPMC)纤维素，10～13份聚羧酸减水剂，10～15份防冻剂，10～13份膨胀剂，其中STG粉末包括改性硅灰‑玻璃粉、碳化硅钛、氧化石墨烯。本发明的冻融‑溶蚀环境下抗冲磨混凝土外加剂可以有效抑制氢氧化钙的分解，并能够细化孔隙结构，使水工混凝土更加致密，在提高水工混凝土抗溶蚀的能力的同时增强了其抗冲磨性能，该外加剂具有良好的耐低温性能，可以适用于寒冷低温环境中，对于低温条件下的抗冲磨强度有着明显的提高。
