Cutter Holding Device

Image
There are several methods of supporting a rotating milling cutter with the machine spindle depending on the design of the cutter.
Different Types of Cutter Holding Devices 
    1. Arbors
    2. Collets
    3. Adapters
    4. Screwed on cutters


How to choose Cement?

Image
The cement can be chosen by initially identifying whether our purpose is structural or non-structural in nature. So first we will discuss what structures come under these categories.

What is Doppler's Effect ?? - Engineering

Image
The Doppler Effect or the Doppler Shift is defined as the change in frequency of a particular wave for an observer who is moving relative to the source of the wave. This effect is named after the Austrian Physicist Christian Doppler. He proposed the Doppler Effect in the year 1842 in Prague.

Compound Wall Construction Vaasthu

Image
Compound wall construction is the process that is performed before starting the construction of the house/building. We will look into the different steps that are taken care of during the construction process of a compound wall incorporating the features of vasthu.


Structural & Non-Structural Cracks

Image
Cracks in building after its construction i.e. during their service period is a common phenomenon. These cracks are caused due to the action of superimposed loads or any other external factors. Cracks are said to develop in the building when the stress created in the building components exceeds the strength of the individual components. 


Factors Affecting The Choice of Mix Proportions

Image
The various factors that affect the choice of mix proportions are:
Compressive strengthWorkabilityDurabilityMaximum Nominal Size AggregateGrading and Type of AggregateQuality Control
Compressive Strength
It is one of the most important Properties of concrete and influences many other desirable properties of the hardened concrete. The mean compressive strength that is required at a specific age usually 28 days, will determine the nominal water-cement ratio of the mix. The other factor affecting the strength of the concrete at a given age and cured at a prescribed temperature is the degree of compaction. According to Abraham's law, the strength of fully compacted concrete is inversely proportional to the water-cement ratio.
Workability  The degree of workability required depends on the below mentioned three factors:
i. Size of the section to be concreted ii. Amount of reinforcement iii. Method of compaction that is used


Durability The durability of concrete is its resistance to the a…

What is Floating Column?

Image
Floating column is a column member that is constructed over the beam, unlike normal columns. The floating column construction is a new development made to serve a certain architectural purpose in the building construction.

Brick Construction Know How

Image
To clearly understand the real concept in masonry construction, we will have to start from the basics. A civil engineer must have equal and above knowledge of a mason, even though he is the person executing the work and we are the one who supervises.
What are the faces in Brick?
The brick will have a header face, a stretcher face and a bed face, as shown in the figure-1 below.

What is the Dimension of the Brick? There is two dimension to brick. They are: Specified DimensionNominal DimensionExternal DimensionAperture dimension The specified dimension is the actual or theoretical dimension of brick that is measured directly from the brick.
The nominal dimension is the dimension of the brick that is used in the construction plans. This is the sum of actual dimension + the construction joint.
External dimension is the wall thickness. It is the difference between the specified dimension and one joint. This will hence will miss a joint
Aperture dimension will have a joint. This will be the …

What is M25??

Image
M25 is a representation for a grade of concrete used in construction. This shows the strength that is attained by the concrete cast from this type at 28th day. The M25 grade concrete comes under the nominal concrete category which can be easily designed with the help of IS 10262:2009.
