[0002] Concrete is an engineering composite material widely used in civil engineering, such as buildings, roads, bridges, etc. It is mainly composed of cement, sand, stone and water. Chemical admixtures and mineral admixtures can be added when necessary to improve its performance. During the production process of concrete, a slump test is usually performed to determine the fluidity of the mixture, supplemented by intuitive experience to assess cohesion and water retention, and a slump barrel is often used for testing.
