Strength, Stiffness, Non-Linearity, and the Volumetric Response of Concrete Under Triaxial Compression

Abstract

Concrete is a ubiquitous material used in construction that exhibits a wide range of mechanical properties depending on its formulation, manufacturing, and curing processes. In particular, “the strength, stiffness, non-linearity, and volumetric response of concrete under triaxial compression” are of great interest to engineers and scientists alike. The paper desires to deliver an overview of the current state-of-the-art regarding concrete's “strength, stiffness, non-linearity, and volumetric response under triaxial compression”. The paper first introduces the mechanical property of concrete and their influence on its strength and stiffness, along with the effect of “non-linearity” on the response of concrete “under triaxial compression”. Subsequently, the paper discusses the volumetric response of the concrete under “triaxial compression”. The Unconfined Compressive Strength (UCS) test is a laboratory test that measures the strength of concrete when it is subjected to a uniaxial or triaxial compressive stress in a confined environment. The test is used to determine the strength characteristics of concrete under various stress states, such as tension, shear, and compression. The results of the UCS test help engineers design structures and evaluate the load-bearing capacity of concrete in a given situation. Finally, the paper summarizes the results and provides recommendations for future studies. Overall, this paper provides a comprehensive overview of the “strength, stiffness, non-linearity, and volumetric response of concrete under triaxial compression”. It is expected that this paper will help as a useful reference for engineers and scientists interested in the study of concrete's mechanical properties.
