Concrete admixture as well as preparation method and application thereof
The invention relates to the technical field of concrete materials, and particularly discloses a concrete admixture as well as a preparation method and application thereof. The concrete admixture is prepared from the following components in parts by weight: 10-20 parts of a water reducing agent, 0.1-0.4 part of epsilon-polylysine hydrochloride, 0.1-0.5 part of starch sodium octenylsuccinate, 0.4-0.6 part of glycerol, 1-3 parts of modified sorbitol and 80-85 parts of water. The concrete admixture can be used as an admixture of premixed concrete and special concrete. When the concrete admixture provided by the invention is applied to the condition of a high-temperature powder material, the phenomenon of rapid setting or false setting of concrete is avoided, the mechanical property and durability of the hardened concrete are ensured while the normal setting time of the concrete and the small time loss of the concrete are ensured, and the concrete admixture has extremely high application and popularization values.
本发明涉及混凝土材料技术领域，具体公开一种混凝土外加剂及其制备方法和应用。所述混凝土外加剂包括以下重量份的组分：减水剂10‑20份、ε‑聚赖氨酸盐酸盐0.1‑0.4份、辛烯基琥珀酸淀粉钠0.1‑0.5份、甘油0.4‑0.6份、改性山梨醇1‑3份和水80‑85份。所述混凝土外加剂可用于作为预拌混凝土和特种混凝土的外加剂。本发明提供的混凝土外加剂在应用于高温粉体材料条件下避免混凝土出现急凝或假凝现象、保证混凝土正常凝结时间及混凝土经时损失小的同时，还保证了混凝土硬化后的力学性能及耐久性能，具有极高的应用推广价值。
