Description

This paper provides answers to the following questions on Construction Management –
1. Explain the significance of material properties in building design –
o Density
o Stress and Strain
o Tensile and Compressive strength
o Elastic and Plastic deformation
o Modulus of elasticity
2. Explain, how combining two materials can result in a material with properties superior to its constituent parts. You may consider materials like Asbestos Cement, Glass reinforced cement (GRC), Polymer- fiber – reinforced concrete, Steel fiber reinforced concrete and Natural fiber reinforced concrete.
3. Analyse the physical and chemical factors that affect the strength, harness and durability of a range of composite materials.
