Problems solved by technology
[0004] The purpose of the present invention is to provide a high-strength fiber salt-corrosion-resistant cement concrete to solve the problem that the existing cement concrete in the preparation process is not environmentally friendly. When the ratio of catalytic materials is out of balance, it is easy to cause the material to expand, resulting in The air content in the material is too large, which affects the overall performance of the cement concrete. It cannot be recycled again if it cannot meet the specified standards, and its resistance to salt corrosion is poor. Buildings in processing plants or coastal areas are susceptible to salt corrosion, resulting in molecules in the cement concrete be destroyed, thereby affecting the overall strength of the concrete

Abstract
The invention discloses high-strength fiber salt corrosion resistant cement concrete. The high-strength fiber salt corrosion resistant cement concrete is prepared from the following materials in parts by weight: 10-25 parts of high-purity graphite, 15-35 parts of hydromica powder, 20-30 parts of gypsum powder, 2-6 parts of sulfate, 5-10 parts of a water reducing agent, 25-40 parts of silicon powder, 15-35 parts of biotite powder, 2-5 parts of kaolinite powder, 10-20 parts of fly ash, 2-4 parts of an early strength agent and 6-8 parts of hydrogen peroxide. The high-strength fiber salt corrosion resistant cement concrete is prepared by the following steps: mixing and stirring an ash powder material and a coating in batches, adding a water reducing agent and hydrogen peroxide in a quantitative proportion, adding sulfate, intensively mixing the two materials after mixing is completed, and finally carrying out temperature-resistant sealing. The high-strength fiber salt corrosion resistant cement concrete is capable of adapting to the surrounding environment weather perferably, can release negative oxygen ions continuouslly, and surrounding benzene and radon gas harmful substances are decomposed, and the situation that the air content in the material is too large due to expansion of the material is avoided, so that the strength and the salt corrosion resistance effect of the material are guaranteed.
Description
Technical field [0001] The present invention relates to the technical field of concrete material, and is specifically a high strength fiber antihydrate cement concrete. Background technique [0002] High-strength concrete as a new building material, with high pressure resistance, strong resistance, large density, low porosity, high-rise building structure, large span bridge structure, and some special structures Application, high-strength concrete is the largest pressure intensity, generally 6 times that of ordinary intensity, so that the section can be reduced, so it is most suitable for high-rise buildings, experiments show that at a certain axial pressure ratio and In the case of a suitable strap rate, high-strength concrete frame columns have better seismic properties. Moreover, the size of the column is reduced, reducing self-weight, avoiding short columns, also benefiting the structure, and improving economic benefits. [0003] However, existing cement concrete is not envir...
