Anti-freezing combination agent, 3D printing concrete and construction method of 3D printing building
The embodiment of the invention provides an anti-freezing composite agent, 3D printing concrete and a construction method of a 3D printing building, and relates to the field of building materials. The anti-freezing combined agent is prepared from the following components in parts by weight: 1.5 to 10 parts of a water reducing agent, 1.5 to 20 parts of a strong electrolyte inorganic salt anti-freezing agent, 0.1 to 1 part of a crystal disturbing agent and 0.1 to 0.5 part of a fatty amine accelerant, wherein the crystal disturbing agent comprises at least one of urea, polyacrylamide, hexamethylenetetramine, formamide, sodium hydrogen sulfite, sodium thiosulfate, beta-cyclodextrin and dimethyl sulfoxide. When the anti-freezing combination agent in the embodiment of the invention is used in concrete, the hardening rate and the hardening strength of the concrete at low temperature can be enhanced, and the construction efficiency is improved.
本申请实施例提供一种防冻组合剂、3D打印混凝土、3D打印建筑的施工方法，涉及建筑材料领域。防冻组合剂的组分按照重量份数计，包括1.5～10份的减水剂、1.5～20份的强电解质无机盐类防冻剂、0.1～1份的扰晶剂、0.1～0.5份的脂肪胺促进剂；其中扰晶剂包括尿素、聚丙烯酰胺、六次甲基四胺、甲酰胺、亚硫酸氢钠、硫代硫酸钠、β—环糊精、二甲基亚砜中的至少一种。当本申请实施例中的防冻组合剂用于混凝土中时，能增强混凝土在低温时的硬化速率和硬化强度，提升施工效率。
