Q = What is the abbreviation of UPVC and ACIA = UPVC = UN Plasticized Poly Vinyl Chloride. ACI = American concrete institute.
Q = What is FlashingThe protection provided such place from where the water penetrates in the building or structure.
Q = What is the ratio of M 20 and M 40 ConcreteM 20 = 1 : 1.5 : 3
M 40 = 1 : 1.3 : 2.1
Q = What is the initial setting time of concreteThe initial setting time of ordinary Portland cement (OPC) is 30 minutes, Low Heat Cement is 60 minutes and Masonry cement initial setting time is 90 minutes.
Q = What is Final setting time of concrete
The final setting time of concrete is 600 minutes or 10 hours.
Q = What is the Volume of Cement Bag
The volume of one cement bag is 50 kg , 1.25 cft or 0.347 cubic meter.
Q = Formula to find the weight of Steel Bars
D²L162.2
Q = What is diameter of needle of vibrator for compaction of concrete.
The diameter of such needle id 40 mm.
Q = What is minimum width of Beam.
The minimum width of beam is 200 mm.
Q = What is curing period of OPC
In the normal condition the curing time is 7 days but in warm weather when it's too dry the curing time become 10 days.
Q = What us distance between Chair blocks
Distance between chair blocks is 800 mm to 1000 mm ( 0.8 m to 1 m).
Q = What us distance between Cover block
Generally distance between Cover block is 600 mm to 1 meter but at site it's used as chair bars.
Q = Why the circular shape steel is more use than other
Circular shape steel bars are use more than others like triangular, rectangular and square shape because it is easy to make and also very economic and low in price. Circular steel is better in stress distribution. There are low chances of failure of circular because like other it has no edges so the load is lie on same place that is why it is more use in columns and other structure.
Q = Who much costs of plastering require to plaster on wood and steel
Three (3) coats are require on wood and steel but it is necessary that little bit of rigidity id also require on it.
Q = what is mallet and why it is use in construction
Mallet is some kind of hammer with wooden front and it is used in concreting in the absence of vibrator we can stroke the column to maintain the concrete because it could not damage the form work or shuttering.
Q = What is number of brick according to thumb's rule
9' Brick work in one cubic meter m3 = 26 Bags5' Brick work in one cubic meter m3 =6.5 BagsMarble Flooring 1 meter square x 1 meter square = 0.3 BagsMarble Skirting 1 running meter = 0.25 kg
Q = What is slope provided in general stair case
The normally slope of stair case is 25 degree to 40 degree according to IS 436.
Q = Why do we provide pile in foundation
If the bearing capacity of soil of 1 cubic meter is less than 24 KN then in that case pile foundation will be provided
Q = What is the least count of theodolite
The least count of theodolite is 20 second
Q = What is the least count of compass
The least count of compass is 30 second.
Q = What is the ratio of beam in width and depth
The width and depth should be greater or more than 0.3
Q = What will be provided if the depth of beam is equal or more than 750 mm
If the depth of beam is equal or more than 750 mm then the stiffener will be provided. Stiffener is the side face reinforcement.
Q = What is the purpose of portal in column is isolated in footing
It helps to share the load and low chances of failure
