A platform for research: civil engineering, architecture and urbanism
The invention discloses an ecological protection layer for improving durability of concrete, a preparation method and application thereof, and relates to the technical field of anticorrosive materials. The raw materials of the magnesium-magnesium-chloride-based composite material comprise the following components in parts by weight: 500-600 parts of magnesium oxide, 200-300 parts of magnesium chloride, 900-1000 parts of fine aggregate, 200-260 parts of water, 10-20 parts of a water reducing agent, 3-8 parts of a water-resistant agent and 25-150 parts of an admixture. According to the magnesium oxychloride cement mortar, on the basis that the water-resistant agent phosphoric acid is added into the magnesium oxychloride cement mortar, the highland barley straw ash is doped to further improve the mechanical and water-resistant performance of the magnesium oxychloride cement, the problem that the water-resistant performance of the magnesium oxychloride cement mortar is insufficient in a soaking environment is effectively solved, the interface bonding performance of the magnesium oxychloride cement mortar and common concrete is improved, and the water-resistant performance of the magnesium oxychloride cement mortar is improved. And the reliability of cooperative work of the magnesium oxychloride cement mortar and the common concrete in the salt lake and saline soil areas is ensured.
本发明公开了一种改善混凝土耐久性的生态防护层、制备方法及其应用,涉及防腐材料技术领域。其原料包括以下重量份数的组分:氧化镁500~600份、氯化镁200~300份、细骨料900~1000份、水200~260份、减水剂10~20份、耐水剂3~8份、掺合料25~150份。本发明通过在氯氧镁水泥砂浆中添加耐水剂为磷酸的基础上,掺入青稞秸秆灰进一步改善氯氧镁水泥的力学及耐水性能,有效解决了氯氧镁水泥砂浆在浸水环境下耐水性能不足的问题,并且提高了与普通混凝土的界面粘接性能,保证氯氧镁水泥砂浆与普通混凝土在盐湖及盐渍土地区协同工作的可靠性。
