 Different between pedestal and column in construction  Pedestal :- when slenderness ratio less then three is called pedestal.  K=l/b<3 Column :-when slenderness ratio gater then three and less then sixty is called column  K=l/b >3<60 Minimum percentage of steel pedestal:-minimum Reinforcement of pedestal is 0.15% Minimum percentage of steel column:-Minimum Reinforcement of column is 0.6 % to 6% Pedestal:- Generally pedestal seen in below plinth level . Column:- column seen any where like below Ground level and above Ground level  Pedestal:- length and bread ratio is always less then three  Column : column are two type short column and long column          Short column :- slenderness ratio and length by breath ratio greater then three and less then twelve is called short column          Long column :- slenderness ratio and length by breath ratio greater then twelve and less then sixty is called long column 

  What is the minimum cement in Rcc for slab         As per is code minimum Grade of concrete M20 and mix ratio is 1:1.5:3 per cum 300 kg/cum. this cement quantity maintain for small structure like G+2,column and slab.         Slab :- Minimum cement is 300kg/cum or mix ratio is 1:1.5:3 (minimum thick of building 125mm )       Column :-  column and slab is same cement and same ratio. (minimum size is 300mm x 300mm )        Beam:- beam also same cement and same ratio. (minimum size is 200mm x 400mm or 300mm x 300mm)       Footing :- Footing also same cement and same ratio .(minimum size is 900 mm  x 900mm and slab thick 150mm isolated 300mm thick)       Brick work:-  for brick work 1:6 ratio maintain .       PCC:-  for Pcc minimum cement is 175kg/cum and M7.5 mix ratio is 1:4:8 ( Minimum thick of the pcc is 75 mm thick like footing pcc and beam pcc and floor pcc,if floor no grad slab 100 mm thick pcc)       Plastering :-   Maintain 1:6 ratio for 12mm thick and 1:4 for 6mm thick.

 What is the different between OPC and PPC ? OPC  full name: Ordinary Portland cement ? PPC full name : Portland porozolona cement ? Both OPC and PPC cement  used for construction purpose but those cement bogies component and setting time heat of hydration , hardness and used purpose, curing period ,grad of cement  are different. main different opc cement and ppc cement are given below Sl no                  OPC Cement                          PPC cement 1. Opc cement initial setting time is more then PPC cement PPC cement initial setting time is less compare to opc cement 2. OPC cement is available in different grades, including 33 Grade, 43 Grade, and 53 Grade, which indicate the compressive strength of the cement. PPC cement does not have specified grades like OPC cement. However, it is commonly available in the market with a standard set of properties suitable for general constru

 What is the internal and external paint ? A Building inside painting are called internal paint and a building out side paint is called external paint those paint are different because out side rain and sunlight come so exterior paint are protect of building form rain and also good looking.  Internal paint :   Light colour better for internal wall ,if light colour in room size is big look like. if deep colour in internal headache come. in bed room three wall one colour . another wall different colour keep in mined one wall there are no door and windows. ceiling good for white colour internal paint like plastic paint ,distemper paint ,texture paint External Paint:   wall are light colour best but in border for deep colour. rain and sunlight protector paint used for external . camouflage paint and texture paint and normal paint are used for external. used:  surface clean and rearing wall if crack and honey come is come one day before water spray in wall  used roller  Laboratory Test Repo
