ABSTRACT

This paper aims to study the mechanical properties of different graded concrete aggregates and discuss the influence of graded concrete performance. Through the literature review, the research status of concrete aggregate gradation at home and abroad is summarized, and the shortcomings of the existing studies are summarized. On this basis, a variety of graded aggregates are selected to prepare concrete specimens, and their mechanical properties are tested, including compressive strength, folding strength and other indexes. The experimental results show that the mechanical properties of different graded concrete aggregate are significantly different, and the strength and deformation of graded matched concrete have important influence. Some graded types of concrete show high strength and stability, while others may decline. Through comparative analysis, this paper summarizes the advantages and disadvantages of various graded types, and puts forward suggestions to optimize the concrete aggregate grading. These suggestions help to more reasonably select and use concrete aggregate in practical engineering and improve the performance and quality of concrete. This study is of great significance for promoting the development and application of concrete technology, and also provides a valuable reference for future research.
