Iam a civil engineer, the development of science and technology of materials in civil engineering, concrete material has been the most widely used building material all over the world. The most famous advantage of concrete is its high compressive strength. However, there are many defects for concrete materials, such as low anticracking performance, bad toughness, low tensile strength, and so on. During the failure of the concrete structure under the action of load, the energy consumed is very limited, and many cracks with different size scale will come into being. The concrete with higher strength has larger brittleness. The existing of a large number of cracks has great adverse influence on the mechanical properties and durability of concrete structures, which will result in shortening of the service life of the structures. The defects of common concrete restrict the application under severe conditions to a large extent. i can work better on this project ,trust me and give this project to me.
