Pre mixed concrete, as an indispensable material in modern construction, has the advantages of high production efficiency, stable quality, and convenient construction.
It is concrete that is pre mixed in a mixing plant with cement, sand and gravel, water, additives, and admixtures according to a certain mix ratio, and then transported to the construction site for direct use.
However, due to the complexity of raw material quality, mix design, production process, transportation, and construction, the quality of ready mixed concrete is prone to fluctuations, such as unstable slump, large strength dispersion, and the occurrence of segregation and bleeding.
These problems not only affect the construction performance of concrete, but also reduce the quality and durability of concrete structures.
Therefore, it is of great practical significance to study the causes of quality fluctuations in ready mixed concrete and take effective and precise control measures.
