摘　　要：As the main component of concrete, aggregate has a significant impact on the performance of concrete. The aggregate is divided into natural aggregate and artificial aggregate according to its source, among which the artificial aggregate is the concrete aggregate obtained by crushing, grinding and screening the rock mined by blasting. The soundness of aggregate is related to the joints of the original rock, the development degree of joints, the porosity, pore distribution, pore structure and water absorption capacity of the original rock. As an important index in concrete aggregate, soundness is an important factor affecting the strength and durability of concrete. When the soundness exceeds the specification index requirements, it is very necessary to study its impact on the strength and durability of concrete. Based on engineering examples, this paper mainly analyzes the influence of different degrees of soundness of aggregate on the performance of concrete, in order to provide some reference for other similar projects.
