Preparation method of phosphogypsum prefabricated part and phosphogypsum prefabricated part
The invention provides a preparation method of a phosphogypsum prefabricated part. According to the preparation method, phosphogypsum concrete is used for replacing traditional cement concrete, basalt fiber ribs are used for replacing traditional steel bars, and a formula of the phosphogypsum concrete is designed, so that organic combination between the phosphogypsum concrete and the basalt fiber ribs can be ensured, the mechanical property of the phosphogypsum prefabricated part meets the use requirements, corrosion of harmful components in phosphogypsum to a reinforced material is effectively prevented, and the durability of the reinforced material is guaranteed. The phosphogypsum prefabricated part is used for replacing a reinforced concrete prefabricated part, a new way for comprehensive utilization of the phosphogypsum is developed, and the purpose of turning waste into wealth is achieved. The phosphogypsum prefabricated part is prepared by adopting the preparation method, the production method is simple, the cost is low, and the phosphogypsum prefabricated part has the characteristics of being light in weight, high in bearing capacity, low in manufacturing cost and the like, and can be widely applied to highway engineering and municipal engineering construction in China, and high-value utilization of the phosphogypsum is realized.
本发明提供的一种磷石膏预制件的制备方法是以磷石膏混凝土代替传统水泥混凝土，以玄武岩纤维筋代替传统钢筋，设计的磷石膏混凝土的配方，可确保磷石膏混凝土与玄武岩纤维筋之间有机结合，使磷石膏预制件力学性能满足使用要求，并有效防止磷石膏中有害成分对加筋材料的腐蚀，保证其耐久性。以磷石膏预制件代替钢筋混凝土预制件，开发了磷石膏综合利用新途径，达到变废为宝的目的。本发明提供的磷石膏预制件采用本申请的制备方法制得，生产方法简单，成本低，具有重量轻、承载力高和造价低等特点，可广泛应用于我国公路工程和市政工程建设，实现磷石膏高价值化利用。
