Phosphogypsum-based regenerated aggregate as well as preparation method and application thereof
The invention discloses ardealite-based regenerated aggregate as well as a preparation method and application thereof, and belongs to the technical field of road building materials. The ardealite-based regenerated aggregate is prepared from the following raw material components in every 100 parts by weight: 49.64 to 60.28 parts of calcined ardealite, 7.09 to 14.23 parts of slag, 3.55 to 10.67 parts of Portland cement, 0.36 to 0.71 part of sodium hydroxide and 28.37 to 28.47 parts of water. Through compounding of various materials, the synergistic effect of all the components is effectively utilized, the raw materials are few in variety, the proportion of phosphogypsum is large, the forming process is simple, convenient and efficient, the prepared phosphogypsum-based regenerated aggregate only needs natural condition maintenance, the maintenance period is short, the strength is high, and the phosphogypsum-based regenerated aggregate can be widely applied to road construction; the method has remarkable economical efficiency, environmental protection performance and comprehensive performance.
本发明公开了一种磷石膏基再生集料及其制备方法和应用，属于道路建筑材料技术领域。该磷石膏基再生集料，每100重量份的原料包括如下组分：煅烧磷石膏49.64～60.28份，矿渣7.09～14.23份，硅酸盐水泥3.55～10.67份，氢氧化钠0.36～0.71份，水28.37～28.47份。本发明通过多种材料的复配，有效利用了各组分间的协同作用，原材料种类少、磷石膏占比大、成型工艺简便高效，制备的磷石膏基再生集料仅需自然条件养护且养护周期短、强度高，能够大量应用于道路建设中，具有显著的经济性、环保性和综合性能。
