Concrete mortar

Abstract

The invention discloses concrete mortar and belongs to the field of mortar. The concrete mortar takes lignite as a raw material; the lignite can be pyrolyzed under a high-temperature condition to generate tar and a coke component; the tar has the effect of sticking each component; the coke component can react with hydroxyl silicate in stone material liquid in a system under the catalysis effect ofnano iron powder to generate a silicon carbide framework, so that a reinforcing effect is realized and the toughness of the system is improved; asphalt fibers are oxidized through potassium permanganate so that the adsorption force of the asphalt fibers on nano magnesium oxide is enhanced, and the adsorption performance of the asphalt fibers on silicon dioxide generated by hydrolyzing tetraethylorthosilicate can also be effectively improved; the early age strength of a cement-based grouting material is improved, and the expansion coefficient of the cement-based grouting material can be adjusted through magnesium oxide, so that the cement-based grouting material is not easy to crack after being cured. By adopting the concrete mortar provided by the invention, the problems that common mortar at present is easy to hollow and rack, and the toughness and mechanical property are poor are solved.

Description

technical field [0001] The invention belongs to the field of mortar, in particular to a concrete mortar. Background technique [0002] Hydraulic structures such as dams and sluices all need flood discharge and water diversion facilities, such as spillways, flood discharge tunnels, scupper holes, water diversion tunnels, etc. These flood discharge and diversion facilities are often subjected to cavitation and erosion by high-speed water flow, and the water flow in some areas In addition to the scouring effect, it will also have an impact on the concrete on the surface of the overflow and flood discharge facilities. Under the scouring and impact of high-speed sandy water flow, the surface of the concrete will often be eroded, resulting in Damage to the overflow surface may endanger the safety of the building in severe cases. Huge sums of money are spent every year to repair and strengthen the damaged buildings. [0003] In order to improve the anti-scouring ability of the su...
