The formula of the quick-hardening and short-curing-period concrete comprises the components: 275 / kg of magnesium oxide, 175 / kg of magnesium chloride, 150 / kg of sand, 200 / kg of stone, 58 / m of a fiber net, 50 / kg of fly ash, 2 / kg of palm fibers, 0.4 / kg of a catalyst, 0.6 / kg of an early strength agent, 0.5 / kg of a water reducing agent, and 350 / kg of water. The processing method of the quick-hardening and short-curing-period concrete comprises the steps: firstly, sequentially adding the magnesium oxide, the magnesium chloride, the sand, the stone, the fiber net, the fly ash, the palm fibers, the catalyst, the water reducing agent and the water into a concrete stirrer, and stirring for 5min; and then adding the early strength agent into the concrete stirrer, and continuously stirring for 10 min. By adopting the concrete prepared by the preparation method, the weight of a concrete product can be reduced, the maintenance period of the concrete product can be shortened, the maintenance cost of building construction is reduced, and a product prepared from the concrete prepared by the preparation method has good damp-proof and waterproof effects.
