The invention discloses an environment-friendly fair-faced concrete pumping agent which comprises the following components in parts by weight: 1 to 3 parts of epoxy group single-terminated silicone oil modified casein, 1 to 3 parts of dihydro- 2,4,6-trioxo-1,3,5-triazine-1,3-(2H,4H)-dipropionic acid/2-(diethanolamine) sodium ethanesulfonate polycondensate, 2 to 4 parts of humic acid, 0.1 to 0.3 part of phosphate modified starch, 0.2 to 0.5 part of an antifoaming agent, 0.5 to 1.5 parts of magnesite powder, 0.5 to 1.5 parts of sucrose octasulphate sodium and 35 to 45 parts of water. The invention further discloses a preparation method of the environment-friendly bare concrete pumping agent. The environment-friendly fair-faced concrete pumping agent disclosed by the invention can effectivelyimprove the phenomenon of honeycomb pitted surfaces on the surface of fair-faced concrete; according to the pumping agent, the workability and fluidity of concrete in the pumping process are guaranteed, the slump retaining and water reducing effects are remarkable, the mixing amount is small, fair-faced concrete using the pumping agent does not bleed water and is good in impermeability, waterproofness and frost resistance, and the pumping agent is environmentally friendly in the preparation and use process and high in economic value, social value and ecological value.
本发明公开了一种环保型清水混凝土泵送剂，其特征在于，包括如下重量份计的各组分：环氧基单封端硅油改性干酪素1‑3份、二氢‑2,4,6‑三氧代‑1,3,5‑三嗪‑1,3(2H,4H)‑二丙酸/2‑(二乙醇胺基)乙磺酸钠缩聚物30‑40份、腐植酸2‑4份、磷酸酯改性淀粉0.1‑0.3份、消泡剂0.2‑0.5份、菱镁矿石粉0.5‑1.5份、蔗糖八硫酸酯钠0.5‑1.5份、水35‑45份。本发明还公开了所述环保型清水混凝土泵送剂的制备方法。本发明公开的环保型清水混凝土泵送剂能有效改善清水混凝土表面蜂窝麻面现象，保证泵送过程中混凝土的和易性和流动性，保坍和减水效果显著，掺量少，使用该泵送剂的清水混凝土不泌水，抗渗防水抗冻性能好，制备和使用过程中绿色环保，经济价值、社会价值和生态价值高。
