The correct answer is LDPE. LDPE stands for Low-Density Polyethylene, which is a type of plastic used for making bubble wraps. LDPE is known for its flexibility, durability, and lightweight properties, making it an ideal material for protecting fragile items during shipping or storage. It has a low melting point, which allows it to be easily molded into the desired shape of bubble wraps. Additionally, LDPE is resistant to moisture and chemicals, providing an extra layer of protection for the packaged items.

178. For a steel space frame type of roof framing system, what is the most appropriate roof covering material?

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.

183. Minimum number of longitudinal bars of a wall footing

Explanation

The minimum number of longitudinal bars required for a wall footing is 3. This is because longitudinal bars, also known as main reinforcement bars, are used to provide strength and stability to the footing. Having at least 3 bars ensures that the load is distributed evenly and the footing can withstand the forces exerted on it. Using fewer bars may compromise the structural integrity of the footing, while using more bars may not provide significant additional benefits. Therefore, 3 bars is the minimum requirement for a wall footing.

Submit

185. Oil stain that prevents mold.

Explanation

Xyladecor is the correct answer because it is a type of wood stain that contains oil, which helps to prevent the growth of mold. The oil in Xyladecor creates a protective barrier on the wood surface, making it more resistant to moisture and therefore less prone to mold growth. This makes Xyladecor an effective choice for protecting wood from both staining and mold.

186. Best to use in installing 6mm thick porcelain ceramic wall tiles.

Explanation

Stone adhesive is the best option for installing 6mm thick porcelain ceramic wall tiles. Stone adhesive is specifically designed for bonding stone and ceramic tiles, making it a suitable choice for this task. It provides a strong and durable bond, ensuring that the tiles stay securely in place on the wall. Additionally, stone adhesive is resistant to moisture and can withstand the weight and pressure of the tiles. Therefore, it is the most appropriate adhesive for installing these specific tiles.

Submit
187. For the time duration enumerated below (in days), which will be the curing duration for concrete to attain approximately 70% of its maximum design strength?

Explanation

The curing duration for concrete to attain approximately 70% of its maximum design strength is typically around 7 days. During this time, the concrete undergoes hydration, a chemical reaction that strengthens and hardens the material. While the concrete will continue to gain strength beyond 7 days, reaching around 70% of its maximum design strength is a significant milestone in the curing process.

Submit
188. Equivalent of 3/16 inch in mm

Explanation

191. Which is not an anodic coating?

Explanation

Zinc coating is not an anodic coating because anodic coatings are typically used to protect metals from corrosion by creating a barrier between the metal and its environment. Zinc coating, on the other hand, is a type of galvanic coating that acts as a sacrificial layer to protect the underlying metal from corrosion. It works by corroding preferentially to the metal it is protecting. Therefore, zinc coating is not considered an anodic coating.

Submit

197. What type of roof commonly uses corrugated G.I. underlay?

Explanation

Clay-tile roofs commonly use corrugated G.I. underlay. This is because clay tiles are porous and can absorb water, so the G.I. underlay acts as a waterproof barrier to protect the underlying structure from water damage. The corrugated design of the G.I. underlay helps to channel any water that may penetrate the clay tiles away from the roof, preventing leaks and maintaining the integrity of the roof.

Submit
198. Rough textured finish of natural granite tiles.

Explanation

Flamed is the correct answer because it refers to the process of exposing the surface of the granite tiles to intense heat, causing the crystals in the stone to burst and create a rough texture. This rough texture provides better grip and makes the tiles suitable for outdoor areas or places where slip resistance is important. The other options - Honed, Polished, and Egg-shell - all refer to different types of smooth finishes, which are not consistent with the rough textured finish of natural granite tiles.

Submit
199. Actual thickness of GA 24 pre-painted long span roofing sheet

Submit
200. Minimum depth range of SPT bore hole.

Explanation

The minimum depth range of an SPT bore hole is 10 - 12m. This means that the depth of the hole should be at least 10 meters and not exceed 12 meters. This depth range is important for conducting Standard Penetration Tests (SPT) which are used to determine the geotechnical properties of soil and rock layers at different depths. By drilling to this depth range, engineers and geologists can gather valuable information about the subsurface conditions and make informed decisions for construction or engineering projects.
