Recycled aggregate reinforcing liquid and preparation method thereof
The invention discloses a recycled aggregate reinforcing liquid and a preparation method thereof, relates to the technical field of recycled aggregate reinforcing liquids, and in particular, relates to the recycled aggregate reinforcing liquid and the preparation method thereof, wherein the recycled aggregate reinforcing liquid is prepared from the following components in percentage by weight: 0.14%-0.23% of sodium carbonate, 0.35%-0.5% of sodium hydroxide, and 1%-1.5% of polyvinyl alcohol. According to the recycled aggregate reinforcing liquid and the preparation method thereof, the problems of rough surface, high porosity, high water absorption and high crushing index of recycled aggregate are solved, the physical property of the recycled aggregate is improved, the good mechanical property of the recycled aggregate is ensured, the mechanical property of the prepared recycled concrete is improved, and the recycled aggregate reinforcing liquid has the advantages of being easy to prepare, obvious in effect, wide in application range and the like, and can be used in the construction waste recycled aggregate production process. The apparent density of the recycled aggregate can be improved by 5%, the water absorption rate can be reduced by 50%, the crushing index can be reduced by 55, and the compressive strength of the prepared recycled concrete can be improved by 10 MPa.
本发明公开了一种再生骨料强化液及其制备方法，涉及再生骨料强化液技术领域，具体为一种再生骨料强化液及其制备方法，由以下重量百分比配置而成:碳酸钠0.14％‑0.23％；氢氧化钠0.35％‑0.5％；聚乙烯醇1％‑1.5％。该再生骨料强化液及其制备方法解决了再生骨料表面粗糙、孔隙率高、吸水率高、压碎指标高的问题，提高其物理性能，保证其拥有较好的机械性，提高制备而成再生混凝土的力学性能，本发明具有制备容易、效果明显、应用范围广等优点，可用于建筑垃圾再生骨料生产工艺中。可提高再生骨料表观密度5％，降低吸水率50％，降低压碎指标55，提高制备而成再生混凝土抗压强10MPa。
