(b) Six materials used on a masonry wall:1. **Bricks**: Commonly used for their durability and ease of laying.2. **Concrete Blocks (Cinder Blocks)**: Used for structural strength and fire resistance.3. **Stone**: Natural stone like limestone, sandstone, or granite for aesthetic and durability.4. **Concrete Masonry Units (CMUs)**: Engineered blocks made of concrete for various applications.5. **Glass Blocks**: Used for natural light and thermal insulation.6. **Engineered Wood Fiber (EWF)**: Used for lightweight and flexible masonry applications.(c) Sketch and label two alternate courses of a Flemish bond:```Course 1: __ __ __ __ __ / / / / / \ / / / / / \ __ __ __ __ __Course 2: __ __ __ __ __ / / / / / \ / / / / / \ __ __ __ __ __```- **Header**: The brick in the top row of each course.- **Header**: The brick in the bottom row of each course.- **Stretcher**: The brick laid flat with its short ends exposed.(d) Three functional requirements of a foundation wall:1. **Structural Stability**: The wall must be able to withstand the loads placed on it, including the weight of the building and any external forces such as wind or water pressure.2. **Waterproofing**: The wall must be designed to prevent water from entering the building, which is crucial for protecting the foundation and preventing structural damage.3. **Thermal Insulation**: The wall should have adequate insulation to help regulate the building's temperature and reduce energy costs for heating and cooling.3. (a) Four differences between concrete floor and raised timber floor:1. **Material Composition**: - **Concrete Floor**: Made of concrete, which is a mixture of cement, aggregates, and water. - **Raised Timber Floor**: Consists of wooden planks or boards, often supported by a joist system.2. **Durability**: - **Concrete Floor**: Extremely durable and long-lasting, resistant to wear and tear. - **Raised Timber Floor**: Less durable compared to concrete; susceptible to damage from moisture and pests.3. **Insulation**: - **Concrete Floor**: Generally poor insulator, requiring additional insulation if used in cold climates. - **Raised Timber Floor**: Better insulator due to the natural thermal properties of wood, providing better thermal comfort.4. **Maintenance**: - **Concrete Floor**: Requires less maintenance but can be prone to cracking and needs periodic sealing. - **Raised Timber Floor**: Requires regular maintenance, including cleaning, sealing, and sometimes replacing wooden planks to prevent rot and warping.
