Nano-alumina enhanced concrete pumping agent
The invention discloses a nano-alumina enhanced concrete pumping agent, and relates to the technical field of concrete additives. The nano-alumina enhanced concrete pumping agent is prepared from, by weight, 10-15 parts of nano-alumina, 40-45 parts of volcanic ash, 25-30 parts of modified straw powder, 15-20 parts of beta-naphthalenesulfonic acid sodium-formaldehyde condensate, 13-18 parts of an air entraining agent, 12-16 parts of polyamide resin, 10-15 parts of calcium lignosulfonate, 10-15 parts of erythritol, 8-12 parts of polyurethane, 6-10 parts of calcium superphosphate, 10-15 parts of palm oil, 30-40 parts of waste diesel oil, 50-60 parts of ethanol and 250-300 parts of water. The pumping agent prepared in the invention has the characteristics of high water reduction rate and no chloride ions, can substantially improve the workability of concrete and reduce the water segregation rate, also can greatly reduce the slump loss, and completely meets long-distance transportation and construction requirements of pumped concrete.
