Mechanical Properties of Different Types of Concrete under Triaxial Compression Loading
Understanding the fundamentals and behaviors of concrete is necessary to utilize it in different engineering applications. This study covers the different types of concrete required to design and control concrete mixtures for a wide variety of structures. An attempt is made to evaluate the compressive stress-strain curves for various types of concrete such as normal concrete (NC), high-performance concrete (HPC), high-performance fiber reinforced concrete (HPFRC), and polymer concrete (PC) under triaxial compression test. Experimental results were carried out from different investigations to evaluate various parameters. The stress-strain curve offers valuable information on concrete characteristics. Unlike many other graphs, stress-strain curves are also easy to obtain. Here, valuable mechanical properties such as modulus of elasticity, resilience, toughness, and energy absorption of different types of concretes were determined. These parameters can be derived from stress-strain curves in various confining pressures. Furthermore, the mathematical function (strength increased factor) was provided to predict the compressive strength under various confining pressures for each type of concrete. The results showed that the HPFRC and PC had significant mechanical properties than other types of concrete since HPFRC and PC had the most compressive strength and compressive strain, respectively. Moreover, the results of strength increased factor (SIF) revealed that the polynomial function is helpful in estimating the expected increase in the strength under various confining pressures.
