Concrete segregation repairing agent and preparation method thereof
The embodiment of the invention relates to the technical field of building materials, in particular to a concrete segregation repairing agent and a preparation method thereof. The concrete segregationrepairing agent is prepared from the following components in parts by weight: 10-20 parts of 2-acrylamide-2-methyl propanesulfonic acid, 3-5 parts of acrylic acid, 1-3 parts of fumaric acid, 10-20 parts of acrylamide crystals, 100-120 parts of deionized water and 0.01-0.05 part of potassium persulfate. The beneficial effects are that the concrete segregation repairing agent is formed by polymerization of a high-molecular biopolymer, and the production and use processes are green and pollution-free; acid and alkali resistance is high, compatibility is high, and compatibility is good; the repairing agent does not contain an air entraining component and a thickening component; an aqueous solution of the repairing agent has good viscosity and consistency; when applied to the concrete, the repairing agent can make the concrete have good viscoelasticity, plasticity and toughness, and the phenomena of cracking, hollowing, bubbling, peeling and the like of the concrete can be effectively improved; and bleeding and segregation of the concrete are effectively repaired, so that the concrete structure is more uniform, the pumping performance is not influenced, and the strength of the concreteis not influenced.
本发明实施例涉及建筑材料技术领域，具体涉及一种混凝土离析修复剂及其制备方法，该混凝土离析修复剂包括以下重量份的组分：2‑丙烯酰胺‑2‑甲基丙磺酸10‑20份、丙烯酸3‑5份、反丁烯二酸1‑3份、丙烯酰胺晶体10‑20份、去离子水100‑120份、过硫酸钾0.01‑0.05份。本发明实施例的有益效果为：本发明采用高分子生物聚合物聚合而成，生产和使用过程绿色无污染；耐酸碱性强，兼容性强，配伍性良好；不含引气成分、增稠成分，其水溶液具有良好的粘度和稠度，用于混凝土中，可使混凝土具有良好的粘弹性、塑性和韧性，能有效改善混凝土易出现的龟裂、空鼓、起泡、剥落等现象；有效修复混凝土的泌水和离析，使混凝土结构更均匀，不影响泵送性能，且不影响混凝土强度。
