Cement is a binding material used in construction. It comes in different grades and undergoes various tests to ensure quality.
Cement is a fine powder made from a mixture of limestone, clay, and iron ore.
Grades of cement include OPC (Ordinary Portland Cement), PPC (Portland Pozzolana Cement), and PSC (Portland Slag Cement).
Tests for cement and concrete include compressive strength test, water absorption test, and settin...
Cement is produced through a multi-step process involving heating raw materials to high temperatures.
Raw materials such as limestone, clay, and sand are crushed and mixed in specific proportions.
The mixture is heated in a kiln at high temperatures (up to 1450°C) to form clinker.
The clinker is then ground into a fine powder and mixed with gypsum to produce cement.
The final product is bagged and ready for use in construc...

Schottky diodes have low forward voltage drop, fast switching speed, and low reverse recovery time.
Low forward voltage drop reduces power loss and improves efficiency.
Fast switching speed makes them suitable for high-frequency applications.
Low reverse recovery time reduces switching losses and improves efficiency.
Schottky diodes are commonly used in power supplies, voltage clamping circuits, and RF applications.
Lenz's Law states that the direction of an induced current in a conductor is always such that it opposes the change in magnetic field that produced it.
When a magnet is moved towards a coil, a current is induced in the coil in such a direction that it opposes the motion of the magnet.
When a magnet is moved away from a coil, a current is induced in the coil in such a direction that it opposes the change in magnetic field...
