Cement-based retarder based on natural polyphenol
The invention discloses a cement retarder based on natural polyphenol. The cement retarder is a natural polyphenol material. The natural polyphenol material is tea polyphenol; when the natural polyphenol material is used, the natural polyphenol material needs to be dissolved in advance to be prepared into a stable and uniform solution, and the cement retarder is used for preparing any one of concrete, mortar and neat paste civil engineering materials. When any one of concrete, mortar and neat paste civil engineering materials is prepared, one or more of cement, volcanic ash, hydraulic materials and retarders are adopted as raw materials. The cement retarder disclosed by the invention has a good retarding effect when being used in Portland cement, aluminate cement and sulphoaluminate, and the initial setting time and the final setting time of the Portland cement, the aluminate cement and the sulphoaluminate cement can be effectively delayed by the retarders with different concentration gradients.
本发明公开了一种基于天然多酚的水泥缓凝剂，该水泥缓凝剂为天然多酚材料；所述天然多酚材料为茶多酚；所述天然多酚材料在使用时，需要将其提前溶解，配置成稳定均一的溶液，所述水泥缓凝剂用于制备混凝土、砂浆、净浆土木工程材料中的任意一种；制备混凝土、砂浆、净浆土木工程材料中的任意一种时采用的原料为水泥、火山灰、水硬性材料、缓凝剂中的一种或几种。本发明的水泥缓凝剂用于硅酸盐水泥、铝酸盐水泥和硫铝酸盐中具有良好的缓凝效果，不同浓度梯度的缓凝剂能使硅酸盐水泥、铝酸盐水泥和硫铝酸盐水泥的初凝和终凝时间得到有效延缓。
