Recycled concrete for prefabricated parts and preparation method thereof
The invention discloses recycled concrete for prefabricated parts and a preparation method thereof, and relates to the technical field of recycled concrete, the recycled concrete is prepared from the following components: modified basalt fiber, asphalt, cement, recycled aggregate, water, a water reducing agent, calcium sulfate, fine aggregate, a coupling agent, fly ash and hydroxyethyl cellulose; wherein the coupling agent adopts an organic silane coupling agent; the fine aggregate is river sand, the fineness modulus is 2.2, and the apparent density is 2680kg/m < 3 >; the waste concrete and the broken bricks are adopted, waste recycling, resource saving and environment protection are achieved, sodium lignin sulfonate introduced in the preparation process can be enhanced, the strength of the recycled concrete is further enhanced, the introduced modified basalt fibers can be evenly distributed in the concrete to form a three-dimensional network structure, and the strength of the recycled concrete is improved. The mechanical property of the recycled concrete is improved.
本发明公开了一种预制构件用再生混凝土及其制备方法，涉及再生混凝土技术领域，由以下成分制成：改性玄武岩纤维、沥青、水泥、再生集料、水、减水剂、硫酸钙、细骨料、偶联剂、粉煤灰、羟乙基纤维素；其中偶联剂采用有机硅烷偶联剂；所述细骨料为河砂，细度模数为2.2，表观密度为2680kg/m3；本发明采用废旧混凝土、碎砖块，不仅实现废物回收利用、节约资源、保护环境，还能够增强利用制备过程中木质素磺酸钠引入的，进一步的增强再生混凝土的强度，通过引入的改性玄武岩纤维可以均匀分布于混凝土内部形成三维网状结构，改善了再生混凝土的力学性能。
