Recycled aggregate reinforcing agent and preparation method thereof, and recycled aggregate concrete
The invention discloses a recycled aggregate reinforcing agent and a preparation method thereof, and recycled aggregate concrete. The recycled aggregate reinforcing agent comprises the following components by weight: 1-10 parts of silica fume, 5-25 parts of fly ash, 0.5-10 parts of water glass, 0.8-2 parts of sodium hydroxide, 20-80 parts of mineral powder and 5-20 parts of water, wherein a weightratio of the fly ash to the mineral powder is 1: (2.5-10); a weight ratio of the silica fume to the mineral powder and the fly ash is 1: (10-50); a weight ratio of the water and the water glass to the mineral powder and the fly ash and the silica powder is 1: (1-10); and the mass percent of silicon dioxide in the silica fume is 80-96%, and the average particle size of the silica fume is 0.1-0.3 micron. The recycled aggregate reinforcing agent is used for reinforcing recycled aggregate, so a stone powder content on the surface of the recycled aggregate is effectively reduced; and since the silica fume is added to reinforce slurry on the surface of the recycled aggregate, the working performance of the recycled aggregate in the concrete is better played.
本发明公开了一种再生骨料增强剂及其制备方法及再生骨料混凝土，所述再生骨料增强剂包括以下重量份的各组分：微硅粉1‑10份、粉煤灰5‑25份、水玻璃0.5‑10份、氢氧化钠0.8‑2份、矿粉20‑80份、水5‑20份，所述粉煤灰和矿粉的重量比为1:2.5‑10，所述微硅粉与矿粉+粉煤灰的重量比为1:10‑50，所述水+水玻璃与矿粉+粉煤灰+硅微粉的重量比为1:1‑10，所述微硅粉中二氧化硅的质量百分数为80‑96％，所述微硅粉的平均粒径为0.1‑0.3微米。本发明使用再生骨料增强剂对再生骨料进行增强，有效地降低了再生骨料表面的石粉含量，通过加入微硅粉，对再生骨料表面浆体进行增强，更好地发挥了再生骨料在混凝土中的工作性能。
