High-mechanical-property geopolymer recycled concrete and preparation method thereof
The invention discloses geopolymer recycled concrete with high mechanical property and a preparation method thereof, and belongs to the technical field of concrete production.The preparation method comprises the steps that the surfaces of natural coarse aggregate and recycled coarse aggregate are coated with an interface agent with the thickness of 3 nm, and composite natural coarse aggregate and composite recycled coarse aggregate are formed respectively; the interface agent forms a layer of compact film on the surface of the composite aggregate to effectively fill micropores on the surface of the aggregate, so that the surface of the aggregate is flatter and smoother, and the microstructure of the aggregate is improved. Due to the improvement, micropores and defects in the concrete are remarkably reduced, so that the overall mechanical property of the concrete is greatly enhanced, and the concrete has higher compressive strength and tensile strength and can better meet the requirements of various engineering applications.
本发明公开了一种高力学性能的地聚物再生混凝土及其制备方法，属于混凝土生产技术领域，本发明通过在天然粗骨料和再生粗骨料的表面涂覆厚度为3nm的界面剂，分别形成复合天然粗骨料和复合再生粗骨料；界面剂在复合骨料表面形成了一层致密的薄膜，有效的填充骨料表面的微孔隙，使骨料表面更加平整和光滑，从而改进骨料的微观结构。由于这种改进，混凝土内部的微孔隙和缺陷显著减少，从而使混凝土的整体力学性能大幅增强，具备更高的抗压强度和抗拉强度，能够更好地满足各种工程应用的需求。
