Concrete anti-cracking agent and preparation method thereof
The invention discloses a concrete anti-cracking agent and a preparation method thereof. The concrete anti-cracking agent is prepared from the following components in parts by weight: 1.5 to 4 parts of modified anti-cracking fiber, 2 to 7 parts of modified kyanite, 5 to 8 parts of modified montmorillonite, 0.5 to 1 part of graphene oxide, 1 to 3.5 parts of polymer microspheres, 2 to 4 parts of nano dysprosium oxide, 2 to 4 parts of nano zinc oxide and 10 to 30 parts of gypsum. According to the concrete anti-cracking agent, the modified anti-cracking fiber, the modified kyanite, the modified montmorillonite, the graphene oxide, the polymer microspheres, the nanodysprosium oxide, the nanozinc oxide and the gypsum are reasonably combined to obtain the concrete anti-cracking agent, and the concrete anti-cracking agent has the functions of resisting cracking, supplementing shrinkage and inhibiting shrinkage; after being added into concrete, the concrete modifier greatly improves the strength and crack resistance of the concrete, and is beneficial to improving the durability of the concrete.
本发明公开了一种混凝土抗裂剂及其制备方法，所述凝土抗裂剂包括以下重量份数的组分：改性抗裂纤维1.5～4份、改性蓝晶石2～7份、改性蒙脱土5～8份、氧化石墨烯0.5～1份、聚合物微球1～3.5份、纳米氧化镝2～4份、纳米氧化锌2～4份、石膏10～30份。本发明中的一种混凝土抗裂剂，通过改性抗裂纤维、改性蓝晶石、改性蒙脱土、氧化石墨烯、聚合物微球、纳米氧化镝、纳米氧化锌及石膏的合理配伍得到混凝土抗裂剂，具有抗裂、补充收缩、抑制收缩的功能，加入混凝土中后大大提高了混凝土的强度、抗裂性能，同时有益于混凝土耐久性的提高。
