| titleOfInvention | Ultra-high performance concrete for strengthening underwater concrete structure and preparation method thereof |
| abstract | The invention belongs to the technical field of advanced civil engineering materials, and in particular relates to an ultra-high performance concrete for reinforcing underwater concrete structures and a preparation method. The raw materials used in the invention include cement, mineral powder, fly ash, silica fume, expansion agent, quartz Sand, quartz powder, limestone powder, steel fiber, viscosity modifier, water reducing agent, defoaming agent and water, after weighing the above raw materials according to a certain weight ratio, first add the dry materials into the forced stirring pot and mix them evenly , and then add water or water mixed with water reducing agent and defoaming agent into the pot, continue stirring, and add steel fibers when the mixture is in a uniform fluid state, thereby obtaining the product of the present invention. The invention has the advantages of simple preparation method, good workability, high water-land strength ratio and good underwater bonding performance with ordinary concrete, and can be used for reinforcement of underwater concrete structures, thereby improving the bearing capacity and durability of the structure. |
