Method for preparing low-shrinkage concrete from bagasse ash
The invention belongs to the technical field of concrete preparation, and particularly relates to a method for preparing low-shrinkage concrete from bagasse ash. The method comprises the following steps: calcining and grinding recycled bagasse ash, and carrying out chemical part analysis and performance characterization on the calcined and ground bagasse ash. The bagasse ash is used for replacing cement according to a certain proportion and is mixed with cement, water, natural fine aggregate and natural coarse aggregate according to a certain proportion, and the low-shrinkage concrete with the performance meeting requirements is prepared. When bagasse is calcined at a certain temperature, bagasse ash contains a large amount of amorphous oxide, is internally porous and can be used as an auxiliary cementing material to replace cement, green high-performance concrete is prepared, and self-constriction of the concrete is reduced. Therefore, the method provided by the invention not only can reduce the self-constriction of the concrete, but also can reduce the emission of carbon dioxide, save land and protect the environment.
本发明属于混凝土制备技术领域，具体涉及一种利用甘蔗渣灰制备低缩型混凝土的方法。其是对回收的甘蔗渣灰进行煅烧粉磨，并将煅烧粉磨后的甘蔗渣灰进行化学成分分析和性能表征。将甘蔗渣灰按照一定比例取代水泥，并与水泥、水、天然细骨料和天然粗骨料按照一定的比例拌合，制备出性能满足要求的低缩型混凝土。本发明甘蔗渣在一定温度下煅烧时，甘蔗渣灰含有大量的无定形氧化物，且内部多孔，可作为辅助性胶凝材料取代水泥，制备绿色高性能混凝土，并降低混凝土的自收缩。因此，本发明方法不仅可降低混凝土的自收缩，还可减少二氧化碳排放，节约土地，保护环境。
