Powdery reinforcing material used for enhancing concrete structure strength

Abstract

The invention provides a powdery reinforcing material used for enhancing the concrete structure strength. The powdery reinforcing material is prepared from, by mass, 30-50% of a carrier, 20-25% of fibers, 20-25% of a reinforcing agent, 4-7% of a retarder, 3-6% of a dispersing agent and 3-7% of an active agent, wherein the reinforcing agent is magnesium fluosilicate, anhydrous sodium metasilicate and zinc fluorosilicate with the ratio of (7-10):(4-6):(9-12); the retarder is sodium gluconate, calcium sucrose, phosphorus slag powder and urea with the ratio of (0.7-1.2):(1.2-2.5):(3:5):(0.2-0.3).The powdery reinforcing material can be premixed with concrete before construction, which can enhance the concrete performance and significantly improve the mechanical property and durability of the concrete.

Description

technical field [0001] The invention relates to a concrete reinforcing material, in particular to a powdery reinforcing material for strengthening the strength of concrete structures. Background technique [0002] In recent years, it has been popular in the construction floor industry to add sealant curing agent materials to the concrete surface to increase the surface strength simply and quickly. The method of adding sealing and curing agent materials on the surface is to sprinkle the surface enhancing material on the surface of the constructed concrete to penetrate and react with the silicate material on the surface of the concrete to achieve densification and increase the surface strength. Since these existing sealing and curing agent materials cannot be directly added to the prefabricated but unconstructed concrete, but are only sprinkled on the surface of the constructed concrete, they cannot penetrate into the internal structure of the concrete, so it is impossible to ...

AI Technical Summary

Problems solved by technology

Since these existing sealing and curing agent materials cannot be directly added to the prefabricated but unconstructed concrete, but are only sprinkled on the surface of the constructed concrete, they cannot penetrate into the internal structure of the concrete, so it is impossible to solve the fundamental problem by improving the microstructure. The problem is that the surface of the freshly made floor is smooth, but it cannot be used for a long time, and it is easy to sand after a long time

However, if the existing sealing and curing agent materials are added to concrete, it will cause concrete cracking, pulverization, increased brittleness, and too many side effects, so it cannot be directly added
