This is considered to be the most expensive roof framing system to cover large or huge spaces.
Correct Answer
B. Steel space frame
Explanation
A steel space frame is considered to be the most expensive roof framing system for covering large or huge spaces. This is because steel is a strong and durable material that can support heavy loads and span large distances without the need for additional support columns or beams. Additionally, the design and fabrication of a steel space frame can be complex and require specialized engineering expertise, adding to the overall cost.
2.
For a steel space frame type of roof framing system, what is the most appropriate roof covering material?
Correct Answer
E. Glass
Explanation
Glass is the most appropriate roof covering material for a steel space frame type of roof framing system. This is because glass has a high strength-to-weight ratio, allowing it to be supported by the steel frame without adding excessive weight to the structure. Glass also provides natural light transmission, enhancing the aesthetics of the space and reducing the need for artificial lighting during the day. Additionally, glass is durable, resistant to weather elements, and can be designed to provide thermal insulation and UV protection.
3.
For a Warehouse project with galvanized sheet roofing, what is the spacing support for eaves if this project is in a typhoon-prone area?
Correct Answer
A. 300 mm
Explanation
In a typhoon-prone area, it is important to have strong support for the roofing of a warehouse project. The correct answer of 300 mm suggests that the spacing support for eaves should be 300 mm. This means that the support beams or brackets should be placed at intervals of 300 mm along the eaves of the roof. This closer spacing ensures that the roofing is secure and can withstand the strong winds and potential damage caused by typhoons.

7.
A material other than water, aggregates, and hydraulic cement, used as an ingredient of concrete or mortar, and added to the batch immediately before during its mixing.
Correct Answer
B. Admixture
Explanation
An admixture is a material that is added to concrete or mortar during the mixing process. It is used to modify or improve certain properties of the mixture, such as workability, setting time, strength, or durability. Admixtures are typically added in small quantities and can be chemical or mineral-based. They are not considered part of the main ingredients of concrete, which are water, aggregates, and hydraulic cement. Therefore, the correct answer is admixture.
8.
Which is NOT true about concrete?
Correct Answer
B. Recyclable
Explanation
Concrete is a widely used construction material due to its various properties. However, one property that is NOT true about concrete is that it is recyclable. Unlike materials like glass or metal, concrete cannot be easily recycled. It is a non-renewable resource and once it is used, it is difficult to separate and reuse the components effectively. Therefore, while concrete is economical, impervious to water, lightweight, and fireproof, it is not recyclable.
9.
For the time duration enumerated below (in days), which will be an expensive curing duration for concrete?
Correct Answer
A. 14
Explanation
A curing duration of 14 days would be considered expensive for concrete because it is shorter than the other options listed. Curing is the process of maintaining moisture and temperature conditions in freshly placed concrete to allow it to achieve the desired properties. The longer the curing duration, the better the strength and durability of the concrete. Therefore, a shorter curing duration like 14 days would likely result in weaker and less durable concrete compared to the other options.

44.
The most common size of aggregates used for structural members in a concrete construction.
Correct Answer
B. ¾”- 1”
Explanation
The most common size of aggregates used for structural members in a concrete construction is typically between ¾" and 1". This range of aggregate size provides a good balance of strength and workability for the concrete mixture. It allows for proper bonding between the aggregates and the cement paste, resulting in a strong and durable concrete structure. Using larger aggregates can lead to a decrease in workability and increase the risk of segregation, while using smaller aggregates may result in a weaker concrete mix. Therefore, the ¾" to 1" size range is commonly preferred for structural members in concrete construction.
