Course Outcomes

At the end of the course, students will be able to

• 1. Formulate constitutive behaviour of composite materials – Ferrocement, SIFCON and Fibre Reinforced Concrete - by understanding their strain- stress behaviour.
• 2. Classify the materials as per orthotropic and anisotropic behaviour.
• 3. Estimate strain constants using theories applicable to composite materials.
• 4. Analyse and design structural elements made of cement composites.
