Understanding Construction Materials and Processes
Masonry
Simple: Built with brick and mortar paste (this does not resist lateral flexion or effort – Resists compression)
Confined: This includes support pillars and resists lateral forces – this is framed with reinforced concrete or steel or other materials.
Reinforced: This contains perforated hollow bricks, vertical and horizontal reinforcement.
Other Materials
Steel: Improves the resistance of reinforced concrete – common examples include A44 bar-28H and 63-42H.
Cement: Aggregate + cement + water *

Software Engineering Principles
Modularity
What is a Module?
A program unit that is discrete and identifiable with respect to compiling, combining with other units, and loading.
What is Modularity?
The degree to which a system or computer program is composed of discrete components such that a change to one component has minimal impact on other components.
Modular Programming
A software development technique in which software is developed as a collection of modules.
Benefits of Modular Programming
- Managerial
- Product

Placement of Reinforcing
Concrete is weak in resistance to tensile forces. Reinforcing is used primarily to resist tension and thus prevent cracking or failure of the concrete member under tension.
Tension May Be Induced By:
- Shrinkage of concrete as it hardens
- Temperature changes
- Bending and shear forces
Concrete Cover for Reinforcing Steel
To provide protection of reinforcing steel against corrosion and fire, a minimum cover of concrete must be furnished. Engineer to specify. Recommended cover:
- Slabs/walls
