Comprehensive strength of OPC ranges from 33-53 MPa at 28 days of curing after casting.

• OPC has high compressive strength due to its chemical composition

• It is commonly used in construction for its durability and strength

• The strength of OPC increases with time and proper curing

• Compressive strength is measured in MPa

• OPC has a comprehensive strength ranging from 33-53 MPa at 28 days of curing after casting

The water absorption capacity of coarse aggregate is 0.5-1%.

• Water absorption capacity is the amount of water that can be absorbed by the aggregate.

• Coarse aggregates are larger than 4.75mm in size.

• Water absorption capacity affects the strength and durability of concrete.

• Examples of coarse aggregates include gravel, crushed stone, and slag.

The width of a highway for one line is typically 3.75 meters.

• The width of a highway can vary depending on the number of lanes and the location.

• In the US, the standard width for a single lane highway is 3.7 meters.

• In Europe, the standard width for a single lane highway is 3.5 meters.

• The width of a highway is important for safety and traffic flow.

• Wider highways can accommodate more traffic and reduce congestion.

The specific gravity of soil particles is the ratio of the weight of a given volume of soil to the weight of an equal volume of distilled water.

• Specific gravity is an important property of soil that helps in determining its suitability for various engineering applications.

• It is used to calculate the void ratio, porosity, and degree of saturation of soil.

• The specific gravity of soil particles is affected by factors such...read more

The most used types of support are roller, pinned, and fixed.

• Roller supports allow for movement in one direction while restricting movement in other directions.

• Pinned supports allow for rotation at the joint but restrict translation.

• Fixed supports restrict both rotation and translation.

• The type of support used depends on the specific engineering application.

• For example, roller supports are commonly used in bridges to a...read more
