Modified recycled bare concrete and preparation method thereof
The invention discloses modified recycled bare concrete and a preparation method thereof. Comprising the following raw materials: 180 to 200 parts of water, 320 to 360 parts of cement, 365 to 390 parts of sea sand, 460 to 490 parts of broken stone, 460 to 490 parts of modified recycled coarse aggregate, 40 to 60 parts of recycled micro powder, 40 to 60 parts of fly ash, 40 to 60 parts of mineral powder, 365 to 390 parts of slag ash, 1 to 2 parts of anti-crack reinforced composite fiber, 6.9 parts of nano silicon dioxide, 4.6 parts of a water reducing agent, 2 parts of a defoaming agent and 2 parts of a water-retaining agent. Wherein the modified recycled coarse aggregate is obtained by treating recycled coarse aggregate with a surface modifier A and a surface modifier B. According to the invention, the modified regenerated waste is used, and the anti-crack reinforced composite fiber is added, so that the composite material has good strength and apparent quality, can achieve a decorative effect without subsequent surface processing, also has the advantage of environmental protection, and effectively reduces carbon emission and construction cost.
本发明公开了一种改性再生清水混凝土及其制备方法，包括以下原料：水180‑200份、水泥320‑360份、海砂365‑390份、碎石460‑490份、改性再生粗骨料460‑490份、再生微粉40‑60份、粉煤灰40‑60份、矿粉40‑60份、炉渣灰365‑390份、抗裂增强复合纤维1‑2份、纳米二氧化硅6.9份、减水剂4.6份、消泡剂2份、保水剂2份。其中改性再生粗骨料是由表面改性剂A与表面改性剂B对再生粗骨料进行处理得到。本发明使用改性再生的废弃物，并添加抗裂增强复合纤维，具有良好的强度和表观质量，无需经过后续表面加工即可达到装饰效果，而且还具有环保的优点，有效降低了碳排放和建造成本。
