what is stuttering and right time of de-shuttering?

-

SHUTTERING= Shuttering is a part of construction, or you may call it as derivative of formwork. Shuttering is a vertical temporary arrangement which is arranged to bring concrete in a desired shape.

or
Formwork which supports vertical arrangement is known as shuttering he gives proper shape concrete.
In a technical point of view, Formwork for column, footings, retaining walls is called as a Shuttering   De-Shuttering time of shuttering (IS 456:2000)
  1. Vertical shutting of Wall, Beam and Column 16-24 Hours.
  2. Internal shutting of Roof slab 3 Days.
  3. Internal shuttering of Beam 7 Days.
  4. Vertical support of Slab. Span less than 4.5 m 7 Days. Span more than 4.5 m 14 Days.
  5. Vertical supports of Beam and Arch. Span less than 6 m 14 Days.

Slump cone test for workability ?  Concrete slump test or slump cone test is to compose the consistency or    workability    of concrete mix ready at the laboratory or the construction site during the procedure of the work. Slump-cone-test-detail   slump cone test is the most simple workability test for concrete, involves general cost and provides instant results. Generally  concrete slump cone test value  is used to search the workability, which indicates w/c ratio, but there are more factors including, mixing methods, dosage, admixtures    properties of materials  etc. also effect the concrete slump value. Slump cone test propertises The  concrete slump cone test  quantify the consistency of fresh  concrete  previous  it sets. It is featured to check the  workability  of freshly ready mix  concrete , and therefore the ease with which  concrete  flows in casting time. It can also be used as an indicator of an inaccurate mixed batch. image source-google| image by  Engineer Moi

Thumb rule for every civil Engineers Thumb rule  Introducti n Thumb rules play a most important role during work in construction site. Thumb rules enable you to calculate idea using a simple maths formula and make smart conclusion whenever needed. Remember, Thumb rules is not give the accurate result, but you can use them for roughly results. There are many thumb rules which we apply in construction site. more knowledge of civil engineeering vist civilengineersgyan.blogspot.com  Thumb rule features  thumb rule is an approximatly & comparing method in civil engineering. In thumb rules, The units are not the same when we compare to get the  possitive results.Here I am discussing the most frequently used Thumb rules on construction site.
