Abstract

The invention discloses a formula and processing method of quick-hardening and short-curing-period concrete. 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.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to the formulation and processing method of concrete with rapid hardening and short curing period. Background technique [0002] Concrete is a general term for composite materials made of gel material, aggregate and water in an appropriate proportion, and then hardened after a certain period of time. It is the most widely used artificial civil construction material in the world. Concrete has high hardness and a wide range of raw materials. The cost is low, and it is widely used in structures such as houses, roads, military projects, and nuclear power plants. However, the existing concrete products are heavy, poor in sound insulation, and long in maintenance cycles, which are increasingly unsuitable for building construction. . Contents of the invention [0003] The purpose of the present invention is to provide fast hardening, short curing period concrete formula and processing ...
