Experimental investigation of the properties regarding the strength and durability of a concrete composite reinforced with polypropylene and carbon fiber

For many civil engineering projects in developing nations, concrete is the go-to "manmade" material. In fields where environmental consciousness is growing, the value of concrete’s eco-friendliness is rising. The mortar-aggregate interface is the source of the microcracks that make concrete so brittle. Concrete with fibre reinforcement has been developed to combat the underlying problems. Due to their discontinuous nature, fibres are typically added to concrete in a manner that ensures they are blend in seamlessly and boost the concrete’s properties in all directions. One such attempt to employ only fibres is presented here. Compressive testing was conducted on cube and cylinder specimens with dimensions of 150mm x150mm x 150mm using a method that provided the full compressive strength. The durability and strength of concrete mixed with different mix types are compared to those of standard concrete. In the current project work, Fiber reinforced composites are fabricated using carbon fibres at volume fractions of 1, 1.5, 2, 2.5, and 3% and polypropylene (PP) fibre at volume fractions of 0.5, 1%, 1.5%, 2.5%, and 3%. The data demonstrates that the material’s tensile strength has improved and that it is more resistant to cracking. Proposed sample has 7, 21, and 28 days of curing time. The proof of the FRC’s effectiveness under extreme loads will be in how well it confines the structure.
