Problems solved by technology

[0003] However, the cement produced by them has limited adhesion and strength, and during long-term use, metal components such as steel bars in cement products are susceptible to electrochemical corrosion, which will reduce the service life of cement products. In some specific buildings In the place of use, when the cement is not bonded enough, the connection between the building products will not be strong enough, and it will easily fall off the wall

Abstract

The invention discloses a production method for high-strength cement, and belongs to the field of cement. The high-strength cement is prepared from the following components in parts by weight: 20-30 parts of sandy soil, 15-30 parts of coal gangue, 50-65 parts of flue gas desulfurization gypsum, 1-3 parts of ferrous ionic compounds, 5-10 parts of modified aramid fiber-carbon fiber, 2-5 parts of metal wires, 1-3 parts of a defoaming agent, 10-25 parts of deionized water, 1-4.5 parts of a reinforcing agent and 3-6 parts of an adhesive. The production method has the advantages of being more scientific and reasonable, the strength of a cement finished product can be well improved, the phenomenon that steel bars is subjected to electrochemical corrosion can be well avoided, the service life of the cement product is effectively prolonged, the adhesive force of the cement finished product is effectively improved, the adsorbability of the cement can be well improved, and the connection among building products is more stable.

Description

technical field [0001] The invention relates to the field of cement, in particular to a production method of high-strength cement. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can be hardened in air or better in water, and can firmly bond sand, stone and other materials together. The mixture of early lime and volcanic ash is very similar to modern lime pozzolanic cement. It glues concrete made of gravel. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementitious material, it has been widely used in civil engineering, water conservancy, national defense and other projects. There are many existing methods for producing cement. [0003] However, the cement produced by them has limited adhesion and strength, and during long-term use, metal components such as steel bars in cement products are susce...
