Experimental analysis on the effect of temperature on FRC with synthetic fibers

In general, this thesis should contribute to understand the behaviour of Fibre Reinforced Concrete (FRC) containing polypropylene fibres. This type of concrete is becoming more and more used in the field of construction. Different types of tests are going to be performed to define the durability of the material. The investigation includes a series of experimental tests to assess compressive strength, fibre tensile strength and flexural strength. The aim of the thesis is to understand the effect of temperature through different tests. Some aspects related to their durability are not yet fully understood. Among these there is the effect of temperature on their mechanical behaviour in cracked conditions. In fact, both the elastic modulus and the strength of the polymers used to make macro synthetic fibres are sensitive to temperature variations The abstract concludes by identifying existing gaps in knowledge and highlighting the potential contributions of the current study. As FRC with propylene fibres continues to gain importance in the construction industry, this research seeks to provide valuable insights for engineers, researchers, and practitioners involved in the design and application of advanced concrete materials.
