[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and additives added in a certain proportion, mixed evenly, compacted, cured and hardened. In the production process, many factors will affect the quality of concrete. Unqualified concrete will directly or indirectly threaten the personal safety of citizens. Therefore, it is essential to test the quality of concrete, and compressive strength is one of the most important technical indicators for concrete quality testing.
