Q1. What are basic steps to follow during a construction of a skyscraper

Ans.

Basic steps to follow during construction of a skyscraper

Develop a detailed plan and design for the skyscraper
Prepare the site by clearing and leveling the land
Construct a strong foundation to support the weight of the skyscraper
Build the structural frame using steel or concrete
Install utilities such as plumbing, electrical, and HVAC systems
Add exterior and interior finishes to the skyscraper
Complete final inspections and obtain necessary permits before occupancy

Q2. What are the different tests performed on building materials - cement , bricks , mortar , concrete

Ans.

Various tests are performed on building materials like cement, bricks, mortar, and concrete to ensure quality and durability.

Compression test for cement to check strength
Water absorption test for bricks to assess porosity
Slump test for concrete to measure workability
Flexural strength test for mortar to evaluate durability

Q3. What is generally preferred by IHBs in India - one way slab or two slabs

Ans.

Generally, one way slabs are preferred by IHBs in India due to their cost-effectiveness and ease of construction.

One way slabs are preferred for smaller spans and lighter loads.
Two way slabs are preferred for larger spans and heavier loads.
One way slabs are more cost-effective and easier to construct compared to two way slabs.
IHBs in India often prioritize cost and ease of construction in their projects.

Q4. What are the IS codes and their charts specifications

Ans.

IS codes are Indian standards that provide specifications for various products, processes, and systems.

IS codes are published by the Bureau of Indian Standards (BIS) and cover a wide range of industries such as construction, agriculture, and manufacturing.
Some common IS codes include IS 456 for concrete, IS 800 for general construction in steel, and IS 2062 for structural steel.
IS code charts provide detailed specifications for materials, dimensions, quality standards, and te...read more

Q5. Normal range of strength variation of concrete cube testing and cement cube testing

Ans.

The normal range of strength variation for concrete cube testing is typically +/- 15% of the average strength, while for cement cube testing it is typically +/- 10%.

Concrete cube testing: strength variation is usually within +/- 15% of average strength
Cement cube testing: strength variation is usually within +/- 10% of average strength
Factors such as mix design, curing conditions, and testing procedures can affect the strength variation

Q7. How types of cements are being manufactured

Ans.

Various types of cements are manufactured using different raw materials and processes.

Portland cement is the most common type, made from limestone and clay.
White cement is produced with raw materials low in iron and manganese.
Rapid hardening cement has higher C3S content for quick setting.
Low heat cement is used in massive concrete structures to reduce heat generation.
Sulfate-resisting cement is resistant to sulfate attacks in soil or water.

Q8. Difference between concrete cube testing and cement cube testing

Ans.

Concrete cube testing is used to determine the compressive strength of concrete, while cement cube testing is used to determine the compressive strength of cement mortar.

Concrete cube testing involves casting cubes of concrete mix and testing them for compressive strength after a specified curing period.
Cement cube testing involves casting cubes of cement mortar mix and testing them for compressive strength after a specified curing period.
Concrete cube testing is more commonl...read more
