High-strength phosphogypsum-based recycled aggregate and preparation method thereof
The invention discloses a high-strength ardealite-based recycled aggregate which comprises the following components: ardealite, slag powder, cement clinker, steel slag powder, fly ash, silica fume and pipe pile residual slurry, and a preparation method of the high-strength ardealite-based recycled aggregate comprises the following steps: mixing the materials, adding water to form a mixed material, adding the mixed material into a ring mold granulator, and carrying out compression molding by adopting a ring mold and a compression roller, so as to obtain the high-strength ardealite-based recycled aggregate. And then carrying out carbonization curing and natural curing. The high-strength ardealite-based recycled aggregate has the advantages that a preparation process of the high-strength ardealite-based recycled aggregate is simple and easy to implement, the particle size of the recycled aggregate prepared by the method is 3-28mm, and the crushing index of the prepared recycled aggregate meets the gravel standard for buildings when the mixing amount of the ardealite is less than 85%; the high-strength ardealite-based recycled aggregate can be widely applied to the fields of sponge city water permeable brick preparation, wall building block preparation, road water stabilizing material preparation and the like, the recycled aggregate prepared when the doping amount of ardealite is larger than or equal to 85% can be applied to the field of goaf backfilling of various mining areas, and the high-strength ardealite-based recycled aggregate is good in strength performance, can replace natural gravel and is beneficial to energy conservation and environmental protection.
本发明公开了一种高强度磷石膏基再生骨料，其成分包括磷石膏，矿渣粉，水泥熟料，钢渣粉，粉煤灰，硅灰、管桩余浆，其制备方法是将物料混合处理后加水形成的混合物料加入环模造粒机中，采用环模和压辊压制成型，然后进行碳化养护和自然养护。本发明的优点：高强度磷石膏基再生骨料制备工艺简单易行，采用本发明制备出的再生骨料的颗粒粒度为3～28mm，磷石膏掺量小于85％时制备出的再生骨料压碎指标满足建筑用碎石标准，可以广泛应用于海绵城市透水砖制备、墙体砌块制备、道路水稳料制备等领域，磷石膏掺量大于等于85％时制备出的再生骨料可以用于各类矿区的采空区回填领域，高强度磷石膏基再生骨料强度性能好，可以替代天然碎石，有利于节能环保。
