Give the Purpose, Advantages and Disadvantages of Clerestory window?
Vivek Patel
The main purpose of the clearstory window is to provide fresh air and natural light. The clearstory window should be larger as possible. Advantages Better air circulation and natural light emitting Good aesthetic view Due to higher sill level better privacy Save electricity due to natural light BettRead more
The main purpose of the clearstory window is to provide fresh air and natural light.
The clearstory window should be larger as possible.
Advantages
Disadvantages
- Wall slab junction become critical at opening of clearstory
- Costly design
- Due to hight sunlight, there is may be heat problem.
See lessIn construction Project, What is the meaning of the term Float?
Vivek Patel
Float is a spare of time for a particular activity Some activities have some time to lag it without affecting whole project duration time that's call float of that activities See the figure to better understand Activity A to F have zero float that means if activities between A to F lag then whole prRead more
Float is a spare of time for a particular activity
Some activities have some time to lag it without affecting whole project duration time that’s call float of that activities
See the figure to better understand
Activity A to F have zero float that means if activities between A to F lag then whole project duration maybe change
Activity G and H have some float which means we can lag G & H activities up to its float without affecting whole project duration.
See lessWhat is a Floor Area Ratio (FAR)?
Vivek Patel
Floor area is a ratio of two area Floor area = total floor area of all floor of building/total building plot area (land area) FAR is restricted by local jurisdiction authority If FAR is more that mean we can build more floor area or more story for perticular land. Lets see one example Land plot areaRead more
Floor area is a ratio of two area
Floor area = total floor area of all floor of building/total building plot area (land area)
FAR is restricted by local jurisdiction authority
If FAR is more that mean we can build more floor area or more story for perticular land.
Lets see one example
Land plot area is 1600 sq ft
We have 5 story building & each story have 1000 sq ft floor area
FAR = 1000X5 / 1600 = 3.125
Our FAR for this building is 3.125
See lessWhat are the purpose and usage of Plasticizers?Â
Vivek Patel
Plasticizer is used to increase workability in concrete. Due to plasticizer, we can reduce the water-cement ratio up to a certain limit. Basically, water-cement ratio is used for workability and hydration of cement. If the water-cement ratio is higher, the chances of shrinkage crack increases and alRead more
Plasticizer is used to increase workability in concrete. Due to plasticizer, we can reduce the water-cement ratio up to a certain limit.
Basically, water-cement ratio is used for workability and hydration of cement.
If the water-cement ratio is higher, the chances of shrinkage crack increases and also the chance of porous concrete formation due to free water in concrete.
If the water-cement ratio is less than 0.4, then water is insufficient to complete the hydration process of cement, so we required a minimum water-cement ratio is 0.4
The third point is workability; if the water-cement ratio is minimum or Less, then we get less workability, and if we have a higher water-cement ratio, then we get good workability.
The best water-cement ratio is 0.4, but for workability, we add some plasticizer to the concrete. due to plasticizer, we get higher workability
Usage of plasticizer is
- We can reduce water cement ratio
- We can get higher workability
- We can get higher strength because of of lesser water cement ratio and higher workability
- Reduction in cement content
- Due to plasticizer we can make pumpable concrete
- Plasticizer is mostly used in underwater construction and pile foundation
See lessWhat is the meaning of fluxes in hydrology?
Vivek Patel
Fluxes mean inflow- outflow water relationship. Basically fluxes term use in groundwater study. In order to define the water balance or water budget of an aquifer system of soil strata, the individual processes that bring water into or the liftoff of the system must be quantified. Groundwater InflowRead more

- Due to irrigation pumping
- Due to evaporation and transpiration
- Groundwater meet to sea water
- Groundwater passed to string and it lost.
See lessWhat is Soundness Property of Cement?
Vivek Patel
Soundness refers to the ability of hardening cement to retain its volume after setting with any destructive expansion. Unwanted destructive volume expansion occurs due to free lime and magnesia.

Unwanted destructive volume expansion occurs due to free lime and magnesia.
Effect of unsound concrete
The soundness test is performed to identify the soundness property of cement.
See lessWhat is the diffrence between lap length and development length?
Vivek Patel
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?

Why we take smaller dia to calculate lap length?
What is the benefit of smaller dia steel instead of larger dia steel in slab and beam?
Vivek Patel
Benifit of smaller dia over larger dia steel in rcc member Required less development length Better crack prevention Better confinement Basically in beam we use 16-20 mm dia of bar, In column we use 16-25mm dia, In slab we use 10-16mm dia in ordinary residential building
