Production formula and production process of high-performance concrete expansive agent
The invention discloses a production formula and a production process of a high-performance concrete expansive agent, and the high-performance concrete expansive agent is prepared from the following raw materials in parts by weight: 100-200 parts of gypsum, 100-150 parts of fly ash, 60-100 parts of metallurgical lithium slag, 30-50 parts of aluminum sulfate, 20-40 parts of slaked lime, 6-12 parts of a water reducing agent, 6-10 parts of a dispersing agent and 3-5 parts of a surfactant. Gypsum, fly ash, metallurgical lithium slag, aluminum sulfate and slaked lime are stirred and mixed, a water reducing agent, a dispersing agent and a surface activating agent are added into the mixture to be continuously stirred and mixed, the high-performance concrete expanding agent is obtained, fly ash and metallurgical lithium slag are mixed, and after final use, the metallurgical lithium slag effectively improves the strength of concrete; the water reducing agent is combined to reduce the cracking condition of the concrete, the durability of the concrete is improved, and gypsum and fly ash are mixed to play a good lubricating role, so that the concrete is convenient to form.
本发明公开了一种高性能混凝土膨胀剂生产配方及生产工艺，以重量份计，其原料组成包括：石膏100‑200份、粉煤灰100‑150份、冶金锂渣60‑100份、硫酸铝30‑50份、熟石灰20‑40份、减水剂6‑12份、分散剂6‑10份和表面活化剂3‑5份。通过将石膏、粉煤灰、冶金锂渣、硫酸铝和熟石灰搅拌混合后，向混合物中加入减水剂、分散剂和表面活化剂持续搅拌混合得到高性能混凝土膨胀剂，通过粉煤灰和冶金锂渣混合，最终使用后，冶金锂渣有效提高混凝土的的强度，结合减水剂减少混凝土出现开裂的情况，提高混凝土的耐久性，并且，石膏、粉煤灰混合，起到很好的润滑作用，便于混凝土成型。
