The invention belongs to the technical field of concrete admixtures, and discloses a viscosity adjusting type concrete admixture which is prepared from the following substances in parts by weight: 10to 20 parts of modified starch, 5 to 10 parts of N-vinyl amide polymer, 10 to 15 parts of tetrahydroxyethyl ethylenediamine, 0.5 to 3 parts of N-dodecyl alanine and 50 to 75 parts of natural thixotropic material. The viscosity modifier is doped into a concrete mixture so that the cohesiveness of concrete can be effectively improved, aggregate can be stably suspended in the mixture, and the uniformity and the segregation resistance of fresh concrete can be improved.
本发明属于混凝土外加剂技术领域，公开了一种粘度调节型混凝土外加剂，由以下重量份数的物质组成：改性淀粉10‑20份、N‑乙烯基酰胺类聚合物5‑10份、四羟乙基乙二胺10‑15份、N‑十二烷基丙氨酸0.5‑3份、天然触变材料50‑75份。在混凝土拌合物中掺加本发明粘度改性剂，能够有效增加混凝土黏聚性，可使骨料能够稳定悬浮于拌合物中，增加新拌混凝土的均匀性、抗离析性能。
