The invention relates to the technical field of building materials, and aims at providing a method for processing a geopolymer terrace. The method includes the steps that fine sand, rubble, fly ash and blast furnace slag or calcined clay are added into a mixing stirring machine and are dispersed to obtain dry raw materials; industrial water glass or caustic soda and water are added into the dry raw materials to be stirred and mixed to be even till slurry is formed; ground pouring, shaking leveling, slurry extracting, press polishing and forming are carried out; the dry and whitening surface is avoided through watering during early maintenance; after maintenance time is up, water milling is carried out for leveling and polishing, and after cleaning and drying, an oiliness permeating curing agent is sprayed; after the surface of the curing agent is dried, polishing is carried out with resin abrasive disc, the surface is kept clean and dry, maintenance is carried out for 7 days, and the geopolymer terrace is obtained. By means of the method, the whiskering phenomenon can be effectively prevented, and the application range of the geopolymer terrace is expanded. The production technology is simple and free of toxicity and damage; the prepared geopolymer terrace has the advantages of being high in strength, wear resistance and glossiness, not prone to ash rising and sand rising, short in maintenance time and the like, and has the excellent decorating application effect.
