what is the minimum cement in Rcc for slab

 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.

      Tiles :-  For tiles 1:7 ratio maintain.

      Curing :-  as per IS code for winter season 7 days curing required and summer season 10 days curing required.

      Cement :-  Every cement have to expire 3month of manufacturing date.

      IS code :  For Rcc IS code is 456 and Cement IS code is 1489 and reinforcement IS code is 1789

Silt Content Test as per IS Code

Silt Content Test as per IS Code   Take a little sand and rub the same in hand, if palm remain clean it can be assumed that sand is free of silt that called is silt content test . It is hand test. Frequency of testing  Every 20cum or more frequency as decided by engineer in charge  Permissible limit   Acceptance standard -maximum permissible limit silt content shall not be " more than 8%"  as per is code 383 and as per CPWD specification  Note: (i) If silt content is more, corrective action taken should be noted in column 10 and silt content referred after such action  and recorded in the register.             (i) Fine aggregate contenting more silt than allowable percentage shall be washed so that the silt contents are with in prescribed limit for which nothing shall be paid  Test for silt content  The method for determining silt contents is as follows:     A sample of sand to be tested shall be placed with out drying in a 200 ml measuring cylinder the volume of sample shal
