Ultra-long-distance concrete pumping agent
The invention discloses an ultra-long-distance concrete pumping agent. Every 1000 parts by weight of pumping agent is prepared from the following raw materials in parts by weight: 202.00-198.00 partsby weight of a polycarboxylate superplasticizer, 121.20 to 118.80 parts of a slump retaining agent, 5.05 to 4.95 parts of a water-retaining plasticizer, 3.03 to 2.97 parts of a viscosity regulator, 35.35 to 34.65 parts of a retarder, 0.81 to 0.79 part of a defoaming agent, 2.02 to 1.98 parts of an air entraining agent, and balance of water. The components in the pumping agent raw materials are mutually matched and promoted, so that the pumping performance of the pumping agent is improved, the water-retaining, slump-retaining, retarding and lubricating effects of the pumping agent on concrete are enhanced, and finally, the purpose of long-distance pumping of the concrete is achieved while the self-compaction performance of the concrete is ensured.
本发明公开了一种超远距离混凝土泵送剂，每1000重量份的泵送剂由以下重量份的原料制成聚羧酸减水剂202.00‑198.00份；保坍剂121.20‑118.80份；保水增塑剂5.05‑4.95份；粘度调节剂3.03‑2.97份；缓凝剂35.35‑34.65份；消泡剂0.81‑0.79份；引气剂2.02‑1.98份；余量为水。其通过泵送剂原料中的各组分之间相互配合相互促进，进而提高泵送剂的泵送性能，使得泵送剂加强对混凝土的保水保坍缓凝润滑的效果，最终在保证混凝土自密实性能的同时，达到了满足混凝土的远距离泵送的目的。
