The invention is applicable to the technical field of concrete preparation, and provides an environment-friendly concrete additive and a preparation method thereof. The environment-friendly concrete additive comprises the following raw materials: a pyrophosphoric acid titanate coupling agent, activated carbon, polyamide fibers, modified phosphogypsum and modified wollastonite powder. According to the environment-friendly concrete additive provided by the embodiment of the invention, the compressive strength, the anti-permeability grade, the wear resistance and the water permeability of concrete are greatly enhanced by utilizing the mutual synergistic effect of all the components, the bonding performance among aggregates in pervious concrete can be remarkably improved, concrete segregation and bleeding are reduced, and on the basis of ensuring the water permeability, the strength and wear resistance of the pervious concrete are remarkably improved, and the construction quality of a project is ensured; harmless utilization of phosphogypsum is achieved at the same time, the problem of environmental pollution is solved, and on the other hand, resources are saved, waste is turned into wealth, the production cost is reduced, and good economic and social benefits are achieved.
本发明适用混凝土制备技术领域，提供了一种环保混凝土添加剂及其制备方法，环保混凝土添加剂包括以下原料：焦磷酸型钛酸酯偶联剂、活性炭、聚酰胺纤维、改性磷石膏、改性硅灰石粉；本发明实施例提供的环保混凝土添加剂通过利用各组分的相互协同作用，大大增强了混凝土的抗压强度、抗渗等级、耐磨性、透水性，可显著改善透水混凝土中集料间的粘结性能，减少混凝土离析和泌水，在保证透水性能的基础上，显著提高透水混凝土强度和耐磨性能，确保工程的施工质量；同时使用实现了磷石膏的无害化利用，解决了环境污染问题，另一方面节约资源，变废为宝，降低生产成本，具有良好的经济和社会效益。
