What is ties ?
Ties are transverse reinforcement of column
What is stirrups ?
Stirrups is transverse reinforcement of beam

What are the concrete test ?
  • Slump test
  • Compressive strength test
  • Water permeability test
  • Water absorption test
Type of slumps
  • True slumps -   the concrete mass after the test when slumps evenly all around without disintegration is called TRUE slump.
  • Shear slump - when one half of the concrete mass slide down the other is called  Shear slump. This type of slope obtained in a lean concrete mix
  • Collapse slump - when the sample is collapse due to adding excessive water. it is known as collapse slump.
  • Zero slump - for very stiff aur dry mixes. it does not show any changes of the slump after removing the slump cone is called Zero slump.
What do you mean by honeycomb  in concrete ?
 Honeycomb is also known as air pocket is not thing but the air voids in concrete.  it is usually performed during the concrete casting.
What are the common method of curing the concrete ?
  • Spraying
  • Wet covering of surface by gunny bag
  • Ponding
  • Application of curing chemicals
  • Sprinkling
What is grouting ?
Grout is a fluid form of concrete which is used to feel the voids.

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
