Zero-chlorine and low-alkali concrete antifreeze and corrosion resistance pumping agent
The invention discloses a zero-chlorine and low-alkali concrete antifreeze and corrosion resistance pumping agent, and relates to the technical field of building materials. The pumping agent is prepared from, by weight, 50-60 parts of modified starch, 30-40 parts of modified kaolin, 20-25 parts of straw powder, 15-20 parts of aluminum magnesium silicate, 10-15 parts of glazed hollow beads, 12-18 parts of polyacrylamide, 12-18 parts of carboxymethyl chitosan, 10-15 parts of calcium stearate, 8-12 parts of sodium gluconate, 6-10 parts of epoxidized soybean oil, 5-8 parts of polyethylene wax, 20-25 parts of glycerin and 120-150 parts of water. The pumping agent prepared in the invention has the advantages of zero chlorine, low alkali, strong cement dispersion, high water reducing rate, obvious improvement of the workability of concrete, reduction of the slump, and effective adjustment of the setting time of concrete.
