| titleOfInvention | A slump-preserving concrete pumping agent |
| abstract | The invention discloses a slump-preserving concrete pumping agent, which is prepared from the following raw materials in parts by weight: 20-30 parts of naphthalene-based high-efficiency water reducer, 8-diethanol monoisopropanolamine maleate compound 12 parts, glycerin carbonate 5‑7 parts, triethylamine 3‑5 parts, simethicone 0.2‑0.6 parts, retarder 3‑7 parts, fatty alcohol polyoxyethylene ether 0.1‑0.3 parts, water 40‑ 60 servings. In the slump-preserving concrete pumping agent of the present invention, various properties of the naphthalene-based high-efficiency water reducer can be significantly improved by compounding diethanol monoisopropanolamine maleate compound, glycerol carbonate and triethylamine. The performance of the concrete is good, with high durability, high slump retention, and excellent performance of no bleeding; the slump loss is small, and the good workability and pumpability of the concrete can be effectively maintained, which can meet the pumping requirements; for various cements It has strong adaptability and good economic and social benefits. |
