What is the cement consumption?

Coefficients of cement consumption works for various construction activities involving cement mortar, concrete etc….Cement Consumption Coefficients for Various Construction Works.

S. No.	Construction Work Details	Coefficient
2	P.C.C. (1:4:8)	3.4 Bags/cu.mt.
3	P.C.C. (1:3:6)	4.4 Bags/cu.mt.
4	R.C.C. M-15 (1:2:4)	6.3 Bags/cu.mt.
5	R.C.C. M-20 (1:2:4)	8.00 Bags/cu.mt.

How do you calculate the coefficient of cement?

Quantity of cement:-

Quantity of Cement = (Dry Volume of mortar x Cement ratio) / (Sum of the ratio)
Density of Cement = 1440 kg/m³
1 bag of cement contains 50 kg of cement.
Cement : Sand :: 1:4.
Quantity of Sand = Quantity of Cement x 4.
1 m³=35.3147 Cubic Feet (CFT)
Density of sand = 1920 kg/m³

How much cement is used in plaster?

The overall thickness of plastering should be minimum 20mm including two coats. The Volume of each cement bag = 50Kgs/1440 = 0.0348 m3….Different ratios of Cement mortar used for plastering are tabulated below:

Mix Ratio	Areas of usage
1:4	Used for Ceiling and external walls

How do you calculate cement and sand for plastering?

Calculation of quantity of material for 12 mm thick plaster of ratio 1: 6 (1 Cement:6 Sand) in the wall for 100 Sqm

Quantity of Cement = 2/(1+6) × 1 (1 Ratio of cement)
In Kg = 0.30 × 1440 (Density of cement = 1440 kg/m3)
Quantity of Sand = 2/(1+6) × 6 (6 Ratio of sand)
In Cubic Feet = 63.558 cft (1 Cum = 35.31 cft)

How many cement bags make 1m3 of concrete?

Approximately 29 bags are required for 1m3 of cement.

How much aggregate do I need for 1m3 concrete?

Aggregate quantity for 1m3 of M20 concrete: part of aggregate = 3/5.5, density of aggregate = 1550kg/m3, dry volume = 1.54m3, weight = volume × density, weight of aggregate = 3/5.5×1.54m3 ×1550 kg/m3 = 1302kg, so 1302kg aggregate is required for 1m3 of M20 grade of concrete.

Which grade is better in cement?

OPC 53 grade cement is the most preferred building and construction material for projects that require high tensile strength. You can choose to buy OPC 53 grade cement online as it has the grinding of clinkers to the maximum extent and this cement grade is finer than grade 43.
