Q1. What is specific weight of steel
Ans. 
The specific weight of steel is the weight of a unit volume of steel material.
• Specific weight is also known as the unit weight or density of a material.

• It is typically measured in units of kilograms per cubic meter (kg/m³) or pounds per cubic foot (lb/ft³).

• The specific weight of steel can vary depending on the type and grade of steel.

• For example, the specific weight of mild steel is around 7850 kg/m³ or 490 lb/ft³.

• High...read more

Q2. What does M stands for in M20.
Ans. 
M stands for Mix in M20.
• M20 is a designation for the mix ratio of concrete.

• The M stands for Mix, indicating the mix ratio of cement, sand, and aggregate.

• M20 represents a mix ratio of 1:1.5:3, where 1 is cement, 1.5 is sand, and 3 is aggregate.

• Different grades of concrete have different mix ratios, with M20 being a commonly used grade.

Q1. What is ratio of M25 grade
Ans. 
The ratio of M25 grade concrete is 1:1:2.
• The ratio of M25 grade concrete is 1 part cement, 1 part sand, and 2 parts aggregate.

• This ratio is commonly used in construction for various applications.

• For example, if you need to make 1 cubic meter of M25 grade concrete, you would need 1/4 cubic meter of cement, 1/4 cubic meter of sand, and 1/2 cubic meter of aggregate.

Q1. How to find dry density at field
Ans. 
Dry density at field can be found using the sand replacement method.
• Use sand replacement method to find the volume of the hole

• Calculate the weight of the excavated soil

• Divide the weight of soil by the volume of the hole to get the dry density

• Dry density = Weight of soil / Volume of hole

Q2. What is full form of OMC
Ans. 
OMC stands for Optimum Moisture Content.
• OMC is the moisture content at which a soil becomes most workable for compaction.

• It is an important parameter in soil mechanics and geotechnical engineering.

• OMC is determined through laboratory tests like Proctor compaction test.

• Knowing the OMC helps in achieving the desired level of compaction for construction projects.
