Q2. What is the water-cement ratio?
Ans. 
The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• It is a crucial factor in determining the strength and durability of concrete.

• A lower water-cement ratio results in stronger and more durable concrete.

• The typical range for water-cement ratio is between 0.4 to 0.6.

• Excessive water in the mix can lead to lower strength and durability of concrete.

Q3. What is the heat of hydration?
Ans. 
Heat of hydration is the heat released when water is added to cement during the chemical reaction of hydration.
• Heat of hydration is the heat released when water is added to cement during the chemical reaction of hydration.

• It is an exothermic reaction, meaning it releases heat.

• The heat of hydration is important to consider in concrete construction to prevent cracking and ensure proper curing.

• Higher heat of hydration can...read more

Q4. What is curing?
Ans. 
Curing is the process of maintaining adequate moisture and temperature in concrete to ensure proper hydration and strength development.
• Curing helps prevent cracking and ensures the concrete reaches its full strength potential.

• Common curing methods include water curing, membrane curing, and curing compounds.

• Proper curing typically lasts for at least 7 days, but can vary depending on the type of concrete mix and environm

Q5. What is footing and foundation?
Ans. 
Footing is the bottommost part of a foundation that distributes the load of the structure to the soil.
• Footing is typically made of concrete and is wider than the foundation walls to provide stability.

• Foundations are the lower portion of a building structure that transfers the load to the soil.

• There are different types of foundations such as shallow foundations (like spread footings) and deep foundations (like piles).

Q1. How much outer side plaster in mm ?
Ans. 
The thickness of outer side plaster can vary depending on the specific requirements of the project.
• The thickness of outer side plaster is typically around 15-20 mm.

• However, it can be adjusted based on factors such as the type of building, weather conditions, and structural requirements.

• Consulting with a structural engineer or architect is recommended to determine the appropriate thickness for the outer side plaster.

Q2. What is the Grade of concrete for RCC ?
Ans. 
Grade of concrete for RCC is typically M20, M25, M30, etc. which represent the compressive strength of concrete mix.
• Grade of concrete is denoted by the mix ratio of cement, sand, and aggregates.

• Common grades include M20, M25, M30, etc. where 'M' stands for mix and the number represents the compressive strength in MPa.

• Higher grade concrete like M30 is used for structures requiring higher strength like bridges, dams, etc...read more
