Recycled aggregate-containing concrete for preparing fabricated prefabricated bearing platform template
The invention relates to the technical field of concrete, and particularly discloses recycled aggregate-containing concrete for preparing an assembly type prefabricated bearing platform template. The invention discloses recycled aggregate-containing concrete for preparing an assembly type prefabricated bearing platform template. The recycled aggregate-containing concrete comprises the following components in parts by mass: 100 parts of water; 210 to 220 parts of cement; 28 to 30 parts of fly ash; 1115 to 1135 parts of recycled aggregate; 1.4 to 1.6 parts of a water reducing agent; 1.8 to 2 parts of modified plant fiber; the modified plant fibers are prepared by precipitating calcium carbonate on the surfaces of plant fibers through compound microorganisms. The method has the advantages that the strength of the concrete is improved, so that the cracking of the prefabricated bearing platform template is reduced. The recycled aggregate is adopted, material waste can be reduced, energy is saved, space occupation of waste concrete is reduced, the method is more environmentally friendly, and green and environment-friendly effects are well achieved.
本发明涉及混凝土技术领域，具体公开了一种含有再生骨料的用于制备装配式预制承台模板的混凝土。含有再生骨料的用于制备装配式预制承台模板的混凝土，包括以下质量份数的组分：水100份；水泥210‑220份；粉煤灰28‑30份；再生骨料1115‑1135份；减水剂1.4‑1.6份；改性植物纤维1.8‑2份；改性植物纤维由植物纤维通过复合微生物在植物纤维表面沉淀碳酸钙制得。本发明具有提高混凝土的强度从而减少预制承台模板开裂的优点。本发明采用再生骨料，能减少材料浪费，节约能源，减少废旧混凝土对空间的占用，对环境更为友好，较好地实现绿色环保。
