Composite reinforcement method of recycled aggregate
The invention belongs to the technical field of inorganic materials, and particularly relates to a composite strengthening method of recycled aggregate. According to the present invention, the physical strengthening mode and the chemical strengthening mode are compounded, and the ratio of the components in the active slurry is limited so as to form the hard shell on the surface of the recycled coarse aggregate, such that the water absorption rate is reduced, and the micro-powder particles and the cement in the active slurry can fill the gaps in the recycled coarse aggregate so as to achieve the effect of the regeneration of the recycled coarse aggregate; the mechanical property is improved. Data of the embodiment can show that the water absorption rate and the crushing index of the recycled aggregate subjected to composite reinforcement prepared by the composite reinforcement method provided by the invention can reach class I standards.
本发明属于无机材料技术领域，具体涉及一种再生骨料的复合强化方法。本发明通过物理强化和化学强化的方式两种强化方式复合，同时限定了活性浆料中各组分的配比，使其在再生粗骨料表面生成一层“硬壳”，降低吸水率，而且活性浆液中的微粉颗粒和水泥可以填充再生粗骨料中的缝隙，实现其力学性能的提高。经实施例的数据可表明，本发明提供的复合强化方法制备得到的复合强化后的再生骨料的吸水率、压碎指标均可以达到I类标准。
