How to Calculate Bricks and Blocks in a Wall? The bricks & blocks are the most used material in construction work. They are mostly used for pavement & wall construction. In order to do brickwork in your own house or on a construction site, one must need to know how to calculate the bricks & blocks required for its construction. An estimate of such calculation gives a brief idea of how much construction material is required before starting the construction. Here in this articles, we are going to show you how to calculate bricks & blocks required in a wall.

What are the Differences between Pillar & Column? Most people confuse when asked the difference between pillar & column. They often times interchange the meaning of these two terms. These terms share some similarities but they are quite different from each other. In this article, we will explain the differences between pillar & columns using a table chart. Before going into the list of differences, we are going to discuss what pillar & column is. Pillar Pillar is vertical structure designed to bear the  weight of building’s roof  & it can also be used as a  decorative  element in a structure. It can even stand on its own. Column Column is a structural member that transmits the  load of structure to the footing and the soil . In other words, column is a  compressive member  that is constructed from concrete, reinforcement concrete, bricks and blocks etc. Read more about Differences between Pillar & Column read more

What Is A Thyristor (SCR)? How Do They Work, Their Types & Applications A thyristor is a solid-state semiconductor switching device. It is a  bistable  switch that operates in two stable states; non-conducting and conducting state. They are said to be an ideal switch but practically they have some limitations based on their characteristics. They are mostly used in high power circuits.   Symbol Structure States Of Thyristor Working Of Thyristor Forward Blocking Forward Breakdown Gate Switching Reverse Blocking Turn On Methods 1) High Voltage 2) Gate Current 3) Thermal 4) Light 5) dv/dt Thyristor Failure & Its Protection 1  di/dt Protection 2  dv/dt Protection Types Of Thyristor 1) Phase-Controlled Thyristor (SCR) 2) Bidirectional Phase-Controlled Thyristor (BCT) 3) Fast Switching Thyristor (SCR) 4) Light-Activated Silicon-Controlled Rectifier (LASCR) 5) Bidirectional Triode Thyristor (TRIAC) 6) Reverse-Conducting Thyristor (RCT) 7) Gate Turn
