Important point of a civil engineer interview

 What is segregation ?

Separation of cement sand from aggregate in the concrete.
water cement ratio is not proper or As per  IS code height  more than 1.5 meters also segregation.

What is bleeding ?

Water comes out to the surface of concrete is called bleeding. 
It also a type of segregation.

 Function of stirrups ?

To regist shear force and positioning the main reinforcement.

What is the function of foundation?

To increase the suitability of structure.


What is the 3 4 5 method ? 

It is used to set up the plane at right angle.

Full form of DPC ? 

Damp proof course

Minimum die of bored cast insitu pile ?

As per IS 2911 part 1 section 2  =  450 mm.

Factor used to convert weight to dry volume of concrete ? 
 
Is 1.54 

Example :-  if a column wet volume is 3 cum than the dry volume = 3* 1.54= 4.62 cum

CONCRETE POURING IN RAIN- how to pouring concrete in rainy days

  CONCRETE POURING IN RAIN https://askciviltech.blogspot.com/2020/06/knowledge-of-cement-concrete-behaviour.html CONCRETE POURING:- Water is a major component of all concrete. which is mixed with cement and causes it to hydrate and regain strength.  After concrete is laid water can do more harm than good as driving rain. Pouring concrete in the rain can compromise its strength, leading to increased tendency to dust and scaling. Once damage is done. it can be difficult to fix and will often ruin the appearance of the finished surface. Do not let it rain on your parade. Here are some tips to prevent and prevent rain-damaged concrete. Advice for pouring concrete in the rain Despite modern weather forecasting techniques and radar maps, an unexpected rain shower can develop without warning, especially during the hottest months of the year. If rain is in the forecast, you should postpone pouring a large concrete until conditions improve. Even if rain is not predicted you should always be pre

cement plaster or gypsum plaster - which is the best plaster ?

Cement Plaster vs Gypsum Plaster https://askciviltech.blogspot.com/2020/06/knowledge-of-cement-concrete-behaviour.html     The rich contribution of plaster to the beauty and preservation of the surface of the walls need hardly be debated. The most popular types of plaster used for building construction are cement and gypsum plaster. This ointments are used for external and internal plastering of the building.  They form a protective layer that covers stone and brick masonry with RCC walls and ceilings. Additionally, wall plastering is effective in leveling wall and ceiling surfaces, Gypsum and cement are also used to make textures or plaster and finishes. cement plaster:- Cement plaster is a homogeneous mixture made of Portland cement, sand, and water. The thickness of cement plaster is usually between 12 and 20 millimeters, depending on the type of wall or roof surface that needs to be plastered. Note: A rich cement plaster mixture is obtained by mixing one part  The pros Cement plast
