C80 recycled fine aggregate concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to C80 recycled fine aggregate concrete and a preparation method thereof, and the C80 recycled fine aggregate concrete is prepared from the following raw materials in parts by mass: 1205 to 1260 parts of natural coarse aggregate, 425 to 455 parts of recycled fine aggregate, 2.64 to 7.93 parts of basalt fiber, 540 to 580 parts of cementing material, 5.4 to 5.8 parts of water reducing agent and 111 to 124 parts of water. The potassium hydroxide solution is firstly used for pretreating the mixture of the recycled fine aggregate and the basalt fiber to improve the performance of the recycled fine aggregate and the basalt fiber, and then the pretreated mixture is mixed with other raw materials to prepare the concrete with high mechanical strength and good chloride ion penetration resistance. The application of the construction waste recycled fine aggregate in concrete and products thereof is facilitated.
本发明属于建筑材料技术领域，具体涉及一种C80再生细骨料混凝土及其制备方法，包括以下质量分数的原料：天然粗骨料1205‑1260份，再生细骨料425‑455份，玄武岩纤维2.64‑7.93份，胶凝材料540‑580份，减水剂5.4‑5.8份，水111‑124份。本发明先利用氢氧化钾溶液对再生细骨料、玄武岩纤维混合物进行预处理，以改善再生细骨料、玄武岩纤维的性能，然后将预处理后的混合物与其它原料混合，制备具有力学强度高、抗氯离子渗透性能好的混凝土，利于建筑垃圾再生细骨料在混凝土及其制品的应用。
