Modified phosphogypsum-based concrete prefabricated part and preparation method thereof
The invention discloses a modified phosphogypsum-based concrete prefabricated part and a preparation method thereof. The preparation method sequentially comprises the following steps: S1, modificationof phosphogypsum; S2, preparation of concrete; and S3, preparation of the prefabricated part. According to the method, lime pretreatment is adopted, so that the influence of soluble phosphorus and fluorine on the practical performance of ardealite can be eliminated; the precast concrete component prepared from chemical fibers, additives, concrete raw materials, modified ardealite and the like isexcellent in performance and meets the quality requirements of fabricated building construction.
本申请公开了一种改性磷石膏基混凝土预制构件及其制备方法，依次包括如下步骤：S1：磷石膏的改性；S2：混凝土的制备；S3：预制构件的制备。本发明采用石灰预处理可以消除可溶磷、氟对磷石膏实用性能的影响；采用化学纤维、添加剂、混凝土原料、改性磷石膏等制备出的混凝土预制构件性能优良，满足装配式建筑施工质量要求。
