The dry density of soil can be determined with the help of the core cutter method.
Because of change in the moisture content from time to time that’s why there is a... (More)
Jacqueline,
Here you are asking about Life Cycle Assessment (LCA) of structure.
The life span of structure will vary according to the type of structure.
There is no formula available to calculate the life span of any structure.
Different parameters... (More)
Corrosion of steel elements in a facade system may cause failure that can adversely affect building performance.
Preventing or minimising the potential of Steel corrosion in a building involves;
Jantri or land Jantri is actually the legal document released by state governments from time to time that specifies the revised land rates for each area within the state. The rates of lands can’t go below the rates specified in... (More)
Deadmen and tell tales are different from each other. Deadmen are wooden, or bamboo posts or poles set up on continuing excavation to have a rough idea of the excavation depth at some point in time. The position is randomly... (More)
Definition of crazing crack :
Formation of fine crack on the surface of concrete material is called crazing crack of concrete.
Example of crazing crack on concrete is crack in a glaze layer.
Some important... (More)
First of all if possible that we need to remove black cotton soil and make raft foundation with piles
Black cotton soil has very bad property of swelling and shrinkage due to that phenomena, different use settlement of foundation occur... (More)
As a civil engineer leadership is the most important skill a person can have. After completing the graduation a fresher civil engineer handles is site it as a site engineer so he or she must be know how to handle... (More)
there are different types of plaster. Some are given below:
Sand faced plaster is actually a mixture of cement sand mortar which is applied over brickwork and also works as... (More)
The disadvantages of ponding:
Evaporation is high Constant monitoring Excess water is needed The initial work for ponding must be done
However, it is a very simple process and doesn't need skilled labours, thus the disadvantages maybe overruled by that... (More)
The water added to the concrete according to the mix design is well and enough for the complete hydration of the concrete. But due to the loss of moisture and excess heat of hydration, water is lost. To compensate for... (More)
Weigh batching is usually preferred to volume batching. The main drawback of volume batching is that it doesn’t account for the bulking of sand. Due to this bulking, the strength of concrete is compromised.
Weigh batching produces a high quality... (More)
The max size of aggregates is limited to 20mm in RCC to make better compaction and workability.
For different diameters bars lap length, why lap length is calculated with reference to smaller dia ?
Smaller dia may be given less length and bigger dia give higher length
Why we take smaller dia to calculate lap length?
Here if the matter comes about higher modulus of elasticity between rubber or steel then we can say steel is more elastic than rubber. We know that young’s modulus is the ratio of stress to the strain. Therefore, for a... (More)
Generally, shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. The shear resistant of soil is a result of friction and interlocking of particles, and possibly cementation... (More)
The SSSI are sites that are preserved due to its rich flora, fauna, geology and geomorphology. These areas have developed their rich heritage through centuries. Hence they are taken utmost care of. The rules of construction are quite stringent here.... (More)
Modulus of elasticity of concrete is defined as the ratio of the applied stress to the corresponding strain. Not only does it demonstrate the ability of concrete to withstand deformation due to applied stress but also its stiffness. In other... (More)
Proctor test is conducted to identify the compaction of different types of soil at different moisture content.
It is a very important test for structural stability on the construction site.
According to different types of soil & moisture content at... (More)
