Steam-cured concrete member repairing agent and preparation method and application thereof
The invention discloses a steam-cured concrete member repairing agent and a preparation method and application thereof. The repairing agent comprises the following components: 50-66 parts by weight of sand, 1-3 parts by weight of diatomite, 0.6-1.7 parts by weight of an additive, 15-20 parts by weight of water and a composite cementing material formed by 7-10 parts by weight of Portland cement, 7-10 parts by weight of sulphoaluminate cement, 10-15 parts by weight of white Portland cement and 10-15 parts by weight of white alpha semi-hydrated gypsum. By designing a material system of thecomposite cementing material mainly formedby the white Portland cement, the white alpha semi-hydrated gypsum, the Portland cement and the sulphoaluminate cement, the color of the obtained repairing agent is consistent with that of a steam-cured concrete member, so that the problems that since the color difference between a repaired part and the member is large, the appearance quality of concrete steam cured member is poor, and the concrete steam cured member is often mistakenly regarded as a defective goods are overcome, and meanwhile, the problem that the repairing mortar is low in strength and even powder falls off is solved.
本发明公开一种蒸养混凝土构件修补剂及其制备方法与应用。所述修补剂包括如下组分：50～66重量份砂子、1～3重量份硅藻土、0.6～1.7重量份外加剂、15～20重量份水以及由7～10重量份硅酸盐水泥、7～10重量份硫铝酸盐水泥、10～15重量份白色硅酸盐水泥、10～15重量份白色α半水石膏形成的复合胶凝材料。本发明通过设计主要由白色硅酸盐水泥、白色α半水石膏、硅酸盐水泥和硫铝酸盐水泥复合胶凝材料组成的材料体系，使得到的修补剂颜色与蒸养混凝土构件颜色保持一致，克服了修补部位与构件本身存在色差大，导致混凝土蒸养构件外观品质较差，常被误认为残次品的问题，同时解决了修补砂浆强度低甚至掉粉的难题。
