What is Castellated Beam?
Vivek Patel
The castellated beam is a modified steel beam. In which the beam is cut in the central web portion were no great force is present. Cut near to neutral axis of the beam where we required less amount of material mass to resist various force. The opening shape may be hexagonal, rectangular, circular, eRead more
The castellated beam is a modified steel beam. In which the beam is cut in the central web portion were no great force is present.
Cut near to neutral axis of the beam where we required less amount of material mass to resist various force.
The opening shape may be hexagonal, rectangular, circular, etc.
Due to opening in web we get some benifit
- Saving in material
- Lighter weight
- Due to increased depth allowed, we get more strengthen beam
- Good aesthetic view
- Esay handle with roof febrication work.
See lessWhich one should be stronger brick or brick bond?
Vivek Patel
Brick and brick bond both should have the same strength. Because if brick is weak, then brick bond at that time, brick is collapse, and structure cannot remain in stable condition. And if a brick bond is stronger than brick at that time brick bond are collapse and brick remain without bonding. So stRead more
Brick and brick bond both should have the same strength.
Because if brick is weak, then brick bond at that time, brick is collapse, and structure cannot remain in stable condition.
And if a brick bond is stronger than brick at that time brick bond are collapse and brick remain without bonding. So structure cannot remain in stable condition.
So we required brick and brick bonds have the same strength to make a durable structure.
See lessWho have higher modulus of elasticity rubber or steel
Vivek Patel
Modulus of elasticity is the ration of stress and strain. Another way modulus of elasticity is the stress required to generate unit linear strain. It is denoted by E Steel E =200 GPA Rubber E= 0.01 to 0.1 GPA 1GPA= 1000 n/mm2 So we can say that steel have a higher modulus of elasticity than rubber.
Modulus of elasticity is the ration of stress and strain.
Another way modulus of elasticity is the stress required to generate unit linear strain.
It is denoted by E
Steel E =200 GPA
Rubber E= 0.01 to 0.1 GPA
1GPA= 1000 n/mm2
So we can say that steel have a higher modulus of elasticity than rubber.

Vivek Patel
See the figure Pedestal is a compression member who has the length to least lateral dimension ratio is less than 3. It is used at where column load is very high, and we required more depth of footing around column edge to transfer the load and prevent failure of footing, at the time, we provide a peRead more
See the figure
Pedestal is a compression member who has the length to least lateral dimension ratio is less than 3.
It is used at where column load is very high, and we required more depth of footing around column edge to transfer the load and prevent failure of footing, at the time, we provide a pedestal to transfer load safely from column to footing.
Pedestal is usually used in steel structure where the column load is very high.

Vivek Patel
To proceed your of concrete mixing by hand is described step-by-step below First of all clear the floor and apply plastic seat who does not absorb water from concrete mix Now add sand and aggregate and mix it Now add a cement, in hand mixing we required 10% higher cement contain to add Now again mixRead more
To proceed your of concrete mixing by hand is described step-by-step below
The hand mix is not used today, and it is rarely used in the village area for a small work.

See lessfly Ash Percentage in PPC Cements
Vivek Patel
Fly ash is a pozzolana material used to reduce the effect of Ca(OH)2 Fly ash is not cemented material, but it is a pozzolanic materials that react with the cement Ca(OHaOH)2 and make bonds. In general, we replace cement to fly ash 20%, If we add more fly ash, then the strength of the structure becomRead more
Fly ash is a pozzolana material used to reduce the effect of Ca(OH)2
Fly ash is not cemented material, but it is a pozzolanic materials that react with the cement Ca(OHaOH)2 and make bonds.
In general, we replace cement to fly ash 20%,
If we add more fly ash, then the strength of the structure becomes less, and durability also reduced, so we need to add optimum fly ash.
See lessWhat is Supersaturated in Soil?
Vivek Patel
Basically in soil there is 3 part Solids partical Air Water When water added to soil, at that time soil become saturated. And when air contain replace by water and soil become fully saturated at that time soil have two part one is water and one is solid partical. If we add more water than fulRead more
Basically in soil there is 3 part
When water added to soil, at that time soil become saturated. And when air contain replace by water and soil become fully saturated at that time soil have two part one is water and one is solid partical.
If we add more water than fully saturation, hence saturation of soil is 100% or more than that, is called the supersaturated stage.
Water content more than shrinkage limit called supersaturated stage

Vivek Patel
To find SBC there is several several methods like Presumptive sample Analysis Analytical Methods Plate Bearing Test (for settlement & modulus of subgrade reaction) Penetration Test (dcpt cpt etc) Modern Testing Methods (modified test) In site we use generally penitration test In penitratiRead more
To find SBC there is several several methods like
In site we use generally penitration test
In penitration test, 63.5kg hammer are fall from 75cm height free fall and note down reading of penitration
From penitration we can find SBC.
