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
