How to calculate Cement Sand & Aggregate Quantity in Concrete

     ðŸ‘‰How to calculate Cement Sand & Aggregate                                               Quantity in Concrete👈➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤➤

HI guys today i am going to talk about above topic so lets start-

                       M:20 ⇨1:1.5:3 ⇛sum =5.5

                                               where M = Mix 
                                                            1 = cement
                                                             1.5=Sand
                                                              3 = Aggregates

Lets suppose -
                         Length of slab =1 ft
                         width of slab  = 1 ft
                        thickness of slab = 1ft

 VOLUME OF SLAB ➤     = 1x1x1

                                          = 1 Cub Ft ⇛0.0283CubMeter

 Dry volume of concrete = 1.54 Cub Meter

CEMENT âž¤ =(0.0283x1.54x1)/5.5

                     = 0.0079 Cubi Meter
                    
                         0.0079x1440 ⇛1440= Density of cement
                                 
                        =  11.41Kg

SAND ➤ = (0.0283x1.54x1.5)/5.5

                 = 0.011Cub meter
      
                  = 0.011x35.31
                 = 0.388 Cub Ft

AGGREGATE ➤  = (3x1.54x0.0283)/5.5

                                = 0.023 Cub Meter
  
                              = 0.23x35.31 
      
                              = 0.83 Cub Ft
