Q2. Grades of concrete
Ans. 
Grades of concrete refer to the strength of the concrete mix design.
• Grades of concrete are denoted by M10, M15, M20, etc. where M stands for mix and the number represents the compressive strength in N/mm^2.

• Higher grade concrete has higher compressive strength and is used for structural purposes.

• Common grades include M25, M30, M35, and M40 for heavy-duty structures like bridges and high-rise buildings.

Q3. What is slump in concrete
Ans. 
Slump in concrete refers to the measure of consistency of freshly mixed concrete.
• Slump is determined by the amount of water in the concrete mix.

• It is measured by filling a cone-shaped mold with concrete, then lifting the mold to see how much the concrete slumps.

• Different types of slumps (true slump, shear slump, collapse slump) indicate different levels of workability and strength of the concrete mix.

• Slump test is comm...read more

Q4. What is water cement ratio
Ans. 
Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• Water cement ratio 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 ideal water cement ratio varies depending on the type of concrete mix and its intended use.

• For example, a water cement ratio of 0.5 is commonly used ...read more

Q1. Pressure in fire hydrant pipe
Ans. 
Pressure in fire hydrant pipe is determined by factors like water flow rate, pipe diameter, and elevation difference.
• Pressure in fire hydrant pipe is directly related to the flow rate of water through the pipe.

• The diameter of the pipe also affects the pressure, with larger diameter pipes resulting in lower pressure loss.

• Elevation difference between the hydrant and the point of discharge can impact the pressure in the p...read more
