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.

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

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

OCB stands for Oil Circuit Breaker, a type of circuit breaker that uses oil as the medium for arc extinction.

• OCB is commonly used in high voltage applications.

• The oil in OCB helps to extinguish the arc that forms when the circuit breaker interrupts the current flow.

• OCBs are known for their reliability and ability to handle high current interruptions.

• Example: A transformer substation may use OCBs for circuit protection.

APFC Panel stands for Automatic Power Factor Capacitor Panel.

• APFC Panel is used to improve power factor in electrical systems.

• It automatically switches capacitors in and out of the circuit to maintain a desired power factor.

• Helps in reducing electricity bills by avoiding penalties for low power factor.

• Example: APFC Panel is commonly used in industries and commercial buildings.

• It helps in optimizing energy usage and red
