Calcination-free desulfurized gypsum dry-mixed mortar and preparation method thereof
The invention discloses calcination-free desulfurized gypsum dry-mixed mortar which is prepared from the following raw materials in parts by weight at normal temperature: 10-13 parts of calcination-free desulfurized gypsum; 7-17 parts of a concrete cementing material; 40 to 75 parts of concrete coarse aggregate; 2-6 parts of an exciting agent; 0.5 to 1 part of a modifier; 0.07 to 0.1 part of a water retaining agent; 0.1-1 part of a water repellent agent; 0.3 to 0.5 part of an anti-cracking agent; 20 to 26 parts of fine aggregate; 3-5 parts of a solid phase binder; the calcination-free desulfurized gypsum and the concrete cementing material are adopted as main materials, and a solid-phase binder high polymer is added, so that the performance of a final product is improved, the effects of heat preservation, heat insulation, aging resistance and high and low temperature resistance of the mortar are enhanced, the product quality is ensured, and the mortar is suitable for being widely popularized; a mixture of polyvinyl alcohol, copper sulfate powder, powder asphalt and a naphthalene water reducer is adopted as a modifier, polyvinyl alcohol has the effects of setting control and water retention, the powder asphalt can improve the waterproof performance of the material, and the naphthalene water reducer can reduce the water consumption and improve the compressive strength and the breaking strength.
本发明公开了一种免煅烧脱硫石膏干混砂浆，由以下原料在常温下按重量比配制而成，包括：免煅烧脱硫石膏10‑13份；混凝土胶凝材料7‑17份；混凝土粗骨料40‑75份；激发剂2‑6份；改性剂0.5‑1份；保水剂0.07‑0.1份；疏水剂0.1‑1份；抗裂剂0.3‑0.5份；细骨料20‑26份；固相粘结剂3‑5份；膨胀珍珠岩10‑15份，采用免煅烧脱硫石膏和混凝土胶凝材料作为主料，并添加固相粘结剂高聚合物提高了最终产品的性能，增强了砂浆的保温、隔热、抗老化、耐高低温的效果，保证产品质量，适合广泛推广，且采用聚乙烯醇、硫酸铜粉末、粉末沥青、萘系减水剂的混合物作为改性剂，聚乙烯醇具有调凝、保水作用，粉末沥青能够提高材料的防水性能，萘系减水剂可以减低用水量，提高抗压、抗折强度。
