Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a durable concrete brick. Background technique [0002] At present, brick wall materials generally used in construction can be divided into sintered clay bricks, sintered porous bricks, sintered hollow bricks, concrete porous bricks, autoclaved fly ash bricks, and autoclaved lime sand bricks. With the acceleration of development and urbanization, concrete bricks have become the material of choice for construction. With the proposal of high-performance concrete, the durability of concrete has attracted more and more attention from all aspects. However, the service environment of concrete structures is often very complicated, and the durability of the current concrete cannot meet the requirements of the society, and further research and development are needed. Concrete bricks prepared with existing concrete often have the defects of low strength and poor impermeability, resultin...
