Investigation of the compressive strength and flexural strength of concrete with perlite under the effect of high temperature

When the existing literature is examined, it can be seen that many studies have been carried out to improve the mechanical properties of concrete by using waste or additive materials with different mechanical and physical properties in various proportions instead of the conventional aggregate used in concrete production. Within the scope of this study, it was aimed to examine the physical and mechanical properties of the samples fabricated using natural perlite aggregate instead of conventional aggregate by exposing them to high temperature effects. In this context, a total of 96 concrete samples will be fabricated, including 48 rectangular prism beams with dimensions of 10x10x40 cm and 48 cube samples with dimensions of 15x15x15 cm, with a concrete compressive strength of 25 and 40 MPa, using perlite and conventional concrete. The samples were planned to be exposed to temperature effects of 200ºC, 400ºC and 600ºC at room temperature. Afterwards, the samples will be examined with destructive/non-destructive methods such as mass loss (ML), ultra sound transmission rate (USTR), compressive strength (CS), elasticity modulus (EM)and pure bending (PB) test, and the mechanical and physical properties of all samples will be compared.
