How to calculate Cement Sand in Plaster

How to calculate Cement Sand in Plaster

     =====================================

Hi guys today i am going to tell you about above topic so lets start-

 RATIO = 1:6                                                        

where -1= Cement

            6 = Sand

Thickness of Plaster = 12 mm

  Note-
 1- Cement Mortar ratio for wall plastering 1 :6.

           

2- Cement mortar ratio for ceiling plastering 1 :4. 
3- Plastering thickness should not be  more than 12 - 15mm

  if there is need for an additional coat do not do that at one go.

4 - Ensure you are using a good quality
cement.

5 - Must check the manufacturing date of cement it should not be more than 3 months old.

           Volume of Plaster = H x L x T

    If height of plaster = 2 meter

                     Length  = 2 meter

                     thickness = 12 mm ➢0.012Meter

Volume of Plaster =2x2x0.012

                 Volume = 0.048 cub Meter -- Note -this is called wet volume

             Wet Volume = 0 .048 cub meter

 Dry Volume of  Plaster = 0.048 x 1.33

                                        = 0.0638 CubM

CEMENT ➤

                            = (0.0638x1440x1)/7  where 1 = cement ratio 7 = sum of ratio

                           = 13.12Kg

 Convert into bag = 13.12/50

                             =0.26 Bag.

SAND ➤

                     = (0.0638x35.31x6)/7 
where 6 = ratio of sand 7= sum of ratio

                     
                     =1.93 Cub Ft.
