Q1. Which lime is used for white washing
Ans. 
Quicklime is used for white washing.
• Quicklime, also known as calcium oxide, is used for white washing.

• It is a white, caustic, alkaline substance that is produced by heating limestone in a kiln.

• When water is added to quicklime, it undergoes a chemical reaction to form calcium hydroxide, which is used in white washing.

Q3. What is 'M' in M-20 concrete?
Ans. 
M stands for mix design in M-20 concrete, indicating the compressive strength of the concrete mix.
• M-20 concrete is a mix design where 'M' represents the compressive strength of the concrete after 28 days of curing.

• The number '20' in M-20 concrete indicates the characteristic compressive strength of concrete in N/mm^2.

• Different grades of concrete have different compressive strength requirements, with M-20 being a common

Q6. Process of design of one-way and two-way slab and their differences
Ans. 
Design process of one-way and two-way slabs and their differences
• One-way slab design involves calculating bending moments and shear forces along one direction, typically supported on two opposite sides. Two-way slab design considers bending moments and shear forces in both directions, usually supported on all four sides.

• One-way slab design is simpler and more common in practice, while two-way slab design is more comple...read more
