Phosphogypsum cementing material modifier and preparation method thereof, phosphogypsum cementing material and phosphogypsum lightweight aggregate
The invention provides an ardealite cementing material modifier, a preparation method thereof, an ardealite cementing material and an ardealite lightweight aggregate, and belongs to the technical field of building materials. The phosphogypsum cementing material modifier provided by the invention is prepared from the following preparation raw materials in parts by mass: 50 to 100 parts of an over-sulfurized phosphogypsum aggregate waste material powder dehydration phase, 0 to 10 parts of fly ash, 5 to 20 parts of metakaolin, 0 to 10 parts of silica fume, 4 to 12 parts of quick lime and 0 to 0.01 part of a gypsum retarder. The phosphogypsum cementing material modifier provided by the invention can accelerate the setting and hardening speed of the phosphogypsum lightweight aggregate taking the phosphogypsum cementing material as a main component, and improve the mechanical properties of the phosphogypsum lightweight aggregate.
本发明提供了一种磷石膏胶凝材料改性剂及其制备方法、磷石膏胶凝材料、磷石膏轻骨料，属于建筑材料技术领域。本发明提供的磷石膏胶凝材料改性剂，以质量份数计，包括以下制备原料：过硫磷石膏骨料废料粉脱水相50～100份、粉煤灰0～10份、偏高岭土5～20份、硅灰0～10份、生石灰4～12份和石膏缓凝剂0～0.01份。本发明提供的磷石膏胶凝材料改性剂能加快以磷石膏胶凝材料为主要成分的磷石膏轻骨料的凝结硬化速度，提高磷石膏轻骨料的力学性能。
