Sir,
In IS 4926,Mentioned as Concrete Should be Poured With in 2 Hours From time of Batching,why this time limit mentioned,if we are not maintain this time limit what causes are occur &
what are the Remedial action to use this concrete after 2 hours……please Clarify sir..
dear sir, i want a seminar report on “civil engineering & construction”.
I need an explanation of why concrete flatwork placed on plastic or insulation, such as an insulated heated concrete floor does not cure properly. I have poured concrete for 13 years and every year I pour a floor on an insulted surface and 70 percent of the time it will show cracking of the surface before the job is finished, the same day usually 4-6 hours from start of pouring. I know it is caused by water evaporating at different rates because the subgrade is impermeable.
To jim
It depends on the thickness of concrete flatwork. When it is not thick (less than 1m), the inclusion of insulation would give an overall rise in hydration temperature. Hence, it gives higher early thermal movement leading to significant cracks.
On the other hand, if the concrete flatwork is thick, the dominant thermal movement is internal restraint. The use of insulation would even out the temperature differential across the cross section so that the effect of early thermal movement is reduced.
Dear Sir,
Please provide material constants for budget estimation for the projects.
sir,
i am student of B-Tech civil engg student and i have done training in highway and it is interesting field but i want to know that after completion of my work,which field i should adopt for my good career.training is totally different from job so plz give me absolute way.
Hi,
What we should do to protect the RCC roof exposed to the
enviroment direstly , Generally tiles are placed or some
form of brick work is done. Kindly suggest the best
economical and viable solution.
Kind Regards
To Pradip Kumar
In the design of roof of a RC structure, normally the
following components are:
(i) Above the structural finish level of the concrete roof, a screed of uniform thickness is
applied to provide a smooth surface for the application of waterproofing membrane.
(Screed of varying thickness can also be designed on the roof to create a slope for
drainage.) The screed used for providing a surface for membrane should be thin and
possess good adhesion to the substrate. Moreover, the screed aids in the thermal
insulation of the roof.
(ii) Above the screed, waterproofing membrane is provided to ensure watertightness of
the roof.
(iii) An insulation board may be placed on top of waterproof membrane for thermal
insulation. In cold weather condition where the loss of heat at the roof is significant,
the insulation board helps to reduce these losses. On the contrary, in summer the roof
is heated up by direct sunlight and the insulation layer reduces the temperature rise
inside the pumping station.
Hi,
How to prevent the RCC roof exposed to envirenment, generally tiles are used or some form of brickwork.
What is the best viable solution.
Kind Regards.
Hi,
What are remedies available for leakages in expansion joints in monsoon particulrly after hot summer?
To Tushar patel
Expansion joints for concrete structures are not usually intended for 100% watertight. The joint sealant itself could hardly be effective to guard against water entry for external water under pressure.
If the joint is intended to be watertight, it should include during construction stage some form of water barriers such as waterstop.
i want 2 ask..
what is the civil engineering problem..
can u give me exmple…
Can you tell me the safe bearing capacity of soil of Tata Nagar specially Adityapur region for designing the foundation of a building?
To Vikash
Please use Terzaghi’s bearing capacity equation to evaluate the following three components in contribution to the bearing capacity:
(i) Surcharge pressure
Foundations are normally not placed directly on the ground level. Instead, they are installed at a depth below the existing ground level. The soil pressure arising from the depth of soils serves as a surcharge imposing a uniform pressure at foundation level.
(ii) Self-weight of soils
The self-weight of soils contribute to the bearing capacity and is represented by 0.5rBNr (r=density of soils).
(iii) Shear strength
The shear strength of soils contributes to the bearing capacity and is represented by cNc.

hi sir,
how much binding wire required in one ton reinforced steel binding
I am 2nd year student in Civ Eng. I am doing structural analysis of beams with up to 2 redundant reactions. I know how to use the coefficient method (hazardous in some complex situations, so integrals would help) and how to use the defined integral, but I don’t know how to define the progression of the moment through the beam in a certain x direction (the equation given for the moment to be used in the integral).
Could anyone help me?
thank you
sir,,i have to work upon a project named culvert design..sir,pls tell me the key points to be considered while designing,,please sir,,ill b very grateful
