## How to calculate Cement Sand in Plaster

#### =====================================

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

### Dry Volume of  Plaster = 0.048 x 1.33

= 0.0638 CubM

### = (0.0638x1440x1)/7  where 1 = cement ratio7 = 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.

## 👉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
thickness of slab = 1ft

#### VOLUME OF SLAB ➤     = 1x1x1

= 1 Cub Ft ⇛0.0283CubMeter

Dry volume of concrete = 1.54 Cub Meter

#### CEMENT ➤ =(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

## 👉HOW TO CALCULATE No.OF BRICKS &QUANTITY                      OF CEMENT,SAND IN MORTAR👈

--------------------------------------------------------------------------------------------------------------------------

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

Mortar thickness = 10 mm

Ratio = 1:6 👉sum = 1+6 =7

6 = sand.

we are considered VOLUME  = 1 Cub meter.

Volume of brick with Mortar = 200mmx100mm x100mm

Volume =   0.002 Cub meter

No. of bricks in 1 Cubic Meter = 1/0.002

No.s of bricks = 500

Volume of 1 Brick without Mortar = 190mmx90mmx90mm

Volume of 1 Brick without Mortar = 0.001539 Cub Meter

Volume covered by 500 No.s of Brick = 500 x0.001539

= 0.7695 Cub Meter.

Volume of mortar = 1-0.7695
Volume of mortar = 0.2305 👉this is called wet Volume

Now Dry volume of mortar = 0.2305 x1.31      👉Voulme increase 30% when comes into Dry

Dry volume of mortar = 0.306565 Cub Meter

#### CEMENT ➤      = (0.306565x1440)/7 👉Density of cement = 1440 ,sum of ratio = 7

= 63 kg

63/50

1.26 Bags

#### SAND ➤     =(0.306565 X 35.31)6/7 👉 6 = SAND Ratio 7=sum of Ratio

= 9.28 Cub Ft
