Description

technical field [0001] The invention belongs to the technical field of concrete processing. More specifically, it relates to a waterproof concrete and a preparation method thereof. Background technique [0002] Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. [0003] With the continuous development of concrete composition materials, people's performance requirements for concrete are not limited to compressive strength, but on the basis of strength, more attention is paid to the balance and coordination of other indicators of concrete. After...
