2. Quality Control in Construction Materials

Try these first

1. 1.

   What is the minimum cement to sand ratio when mixing mortar?

   Hint

   Think of the common mortar mixing guidelines.

2. 2.

   Why are symmetrical buildings preferred?

   Hint

   Consider how different shapes respond to forces.

3. 3.

   What is the minimum cement-to-sand ratio recommended?

   • 1:5
   • 1:6
   • 1:7

   Hint

   Recall the basic guideline for mixing mortar.

4. 4.

   True or False: Asymmetrical buildings are generally more stable than symmetrical buildings.

   • True
   • False

   Hint

   Consider how design symmetry impacts stability.

5. 5.

   Design a building in a flood-prone area. Discuss how the local culture influences your building choices, including materials and layouts.

   Hint

   Think about the regional architecture and its relationship to environmental factors.

6. 6.

   An asymmetrical building has been subjected to high winds leading to structural failure. What preventative measures could have been integrated at the design stage?

   Hint

   Reflect on design features that counteract external pressures.
