KPR INSTITUTE OF ENGINEERING AND TECHNOLOGY, COIMBATORE EXPERIMENTAL ANALYSIS ON CARBON FIBER REINFORCED CONCRETE (CARBOCRETE) MANOJ.R 711311103032 NAVEENKUMAR 711311103306 RAMACHANDIRAN.D 711311103310 VIJAYAKUMAR.V 711311103315 Under the guidance of P.SELVARAJ KUMAR M.E (Associate Professor-Civil Engineering)

SCOPE: Steel is the most widely used reinforcement in concrete. Use of steel reinforcement is to increase the tensile and shear strength of concrete. In order to increase flexural and tensile strength the additional fibers are used in construction field

OBJECTIVE: The fiber offers high flexural strength and light weight fibers are used to resist corrosion resistance material Fiber have high ductility and durability Fibers have chemical resisting capacity

INTRODUCTION It is a type of concrete that is reinforced with carbon fibers so it’s also known as “Carbon Reinforced Concrete”. It is a new highly stressable lightweight composite construction that combines special fine grain ultra high-strength concrete and carbon fibers. It has higher strength than steel with quarter of its weight.

Carbocrete: Composed of carbon atoms bonded together to form a long chain. A super strong material that's also extremely lightweight. Five times stronger than steel , Two times stiffer , and about Two-Third times less in weight.

Carbocrete Mixing Method Methods: Dry mix Wet mix

Carbon Fibers vs. Steel Up to 75% lighter More durable/corrosion-free 5 times higher tensile strength 2 times higher stiffness Higher temperature tolerance

Carbocrete Mix Design

METHODOLOGY Literature collection Material collection from thermal & steel industries Casting of test specimens with and without cement Curing of specimens Testing of specimen for the strength properties Test results Comparison of test results Discussion of topics Conclusion

TEST FOR carbocrete Compressive Strength Test Flexural Strength Test Slump Test

Advantages & Disadvantages: High tensile strength: Smaller cross-sections Earthquake resistance Expensive: High initial cost Higher durability: Corrosion-free Less running cost Lack of knowledge: Absence of codes No implementations yet Eco-friendly: Less materials needed for maintenance and construction. High thermal conductivity High HVAC consumption Low weight: Easy to handle Risk of lung cancer in the manufacturing phase High flexibility: More creative architectural design High abrasion resistance: Suitable for highway construction Low coefficient of thermal expansion High fire resistance
