Phosphogypsum composite cementing material
The invention provides an ardealite composite cementing material. The composite cementing material comprises the following components: 75-85 parts of ardealite, 5-15 parts of water glass, 3-15 parts of slag powder, 2-10 parts of quick lime, 5-15 parts of cement clinker, 3-6 parts of a water reducer, 2-8 parts of an alkali activator, 1-5 parts of a retarder and 2-6 parts of a stabilizer. Through cooperation of the clinker and the slag powder, OH <-> generated by hydration of the cement clinker can overcome hydrolytic activation energy of a calcium-rich phase in the slag powder so as to excite the activity of the slag powder, the slag powder is hydrated, the hydration rate of a composite cementing material system is increased, hydration products are gradually increased, the compression resistance of the composite cementing material is improved, and the cement clinker can be used as a cement-based composite cementing material. The water glass can chemically react with Ca (OH) 2 in the cementing material to generate CaSi03 and NaOH, so that hydration hardening of the cementing material is promoted, the compressive strength is improved, in addition, the water glass has excellent bonding performance and can block pores in the cementing material, the compactness of a cementing material system is increased, and the compressive strength and the structural strength of the composite cementing material are improved.
本发明提供了磷石膏复合胶凝材料，复合胶凝材料包括以下组成成分：磷石膏75‑85份，水玻璃5‑15份，矿渣粉3‑15份，生石灰2‑10份，水泥熟料5‑15份，减水剂3‑6份，碱性激发剂2‑8份，缓凝剂1‑5份，稳定剂2‑6份。本发明通过数你熟料和矿渣粉的配合，水泥熟料水化生成的OH‑能克服矿渣粉中富钙相的水解活化能从而激发矿渣粉的活性,使其发生水化，复合胶凝材料体系的水化速率加快,水化产物逐渐增多,提高了复合凝胶材料的抗压性能，水玻璃会与胶凝材料中的Ca(OH)2发生化学反应生成CaSi03和NaOH,从而促进了胶凝材料的水化硬化,使抗压强度得到提高，另外水玻璃具有优良的粘结性能，能堵塞胶凝材料中的孔隙,使胶凝材料体系的密实度增加,提高复合胶凝材料的抗压强度和结构强度。
