The amount of cement needed for a house depends on various factors, including the thickness of the walls, type of construction, and local building codes. On average, it might take around 525 to 600 bags of cement for a 1,500 square feet house.

Hi guys in this article we know about quantity of bags of cement is required for 1500 square feet house. Actual quantity of cement calculation is based on as per design but if design is not given then cement quantity calculation is based on Thumb Rule on experience basis & how many cement bags used in construction of 1500 square feet house.

**How many cement bags required for 1500 sq ft house is based on different type of criteria**

1) type of structure (Load Bearing/Framed)

2) Purpose of structure (Load depends on the utility)

3) Type of grade of concrete used

4) Size height of column and length of beam (in terms of height, as requirement varies according to construction i.e. whether horizontal or vertical. )

5) Most important is foundation type(depends on soil bearing conditions)

**How many cement bags required for 1500 sq ft house**

As per thumb rule, on an average **600 bags** of **50kg** cement are required for building a fully furnished **1500 square feet** (sq ft) house. Building a typical house requires **0.4 bags of cement per square foot**, so the amount of bags of cement needed for a **1500 square foot** house is **600 bags** (0.4 × 1500 = 600).

For general residential low rise building of ground floor house we have to calculate cement bags. We use different types of Thumb Rule for cement quantity calculation in all type of RCC structure footing, column, beam & RCC slab,brickwork, flooring & plastering.

Now taking various Thumb Rule for cement quantity calculation for 1500 square feet house

1) Thumb rule for cement in rcc concrete is 0.301 cement bags/ sq ft built up area of low rise ground floor residential building

2) Thumb rule for cement bags in surface ground flooring is 0.089 cement bags/ sq ft of built up area of low rise ground floor residential building.

3) Thumb rule for cement bags in external wall brickwork is 1.26 cement bags/m3 of brickwork of 9 inch (cement sand ratio 1:6)

4) Thumb rule for cement bags in internal wall brick work is 1.28 cement bags/m3 of brickwork of 4.5 inch ( cement sand ratio 1:4)

5) Thumb rule for cement bags for external plastering is 0.017017 cement bags/ sq ft plastering

6) Thumb rule for cement bags for internal plastering is 0.0086 cement bags/ sq ft plastering

7) Thumb rule for cement bags for ceiling plastering is 0.0051 cement bags/ sq ft plastering

**How many cement bags required for 1500 square feet house?**

For the construction of residential building of ground floor we have RCC structure like footing, column, beam and slab. Taking one rough design of 1500 square feet house having different dimension of rcc structure like footing, column, beam and slab are following:

**How many cement bags required for RCC structure of 1500 square feet house**

● volume of rcc concrete calculation

1) footing size = 1500 mm × 1500mm × 300 mm

Length of footing = 1500 mm

Width of footing = 1500 mm

Height of footing = 300 mm

Depth of earth exacavation = 1500 mm

Concrete size in footing = 1200mm×1200mm×300mm

No of footing = 15

Wet volume of concrete in all 15 no of footing = 1.2 m × 1.2 m × 0.3 m × 15 = 6.48 m3

2) column size = 300 mm × 400 mm

No of column = 15

Height above dpc = 3000 mm

Height above rcc slab = 900 mm

Depth of earth exacavation = 1500 mm

Total height of column = 5400 mm

Wet volume of concrete for all 15 column

= 0.3 × 0.4× 5.4 × 15 = 9.72 m3

3) plinth beam size = 300mm × 300 mm

Width of beam = 300 mm

Depth of beam = 300 mm

Overall length of all beam = 300 ft = 90000 mm

Wet volume of concrete = 0.3 × 0.3 × 90 = 8.1 m3

4) door beam size for external wall = 225mm × 150 mm

Overall length for external beam = 160 ft = 48000 mm

Volume = 0.225 × 0.15 × 48 = 1.62 m3

Door beam size for internal wall = 125 mm × 150 mm

Overall length for internal beam = 140 ft = 42000 mm

Volume = 0.125 × 0.15 × 42 = 0.7875 m3

Total volume of concrete = 1.62 + 0.7875 = 2.40 m3

5) roof wall beam size for external wall = 225 mm × 200 mm

Overall length for external beam = 160 ft = 48000 mm

Volume = 0.225 × 0.2 × 48 × = 2.16 m3

Roof wall beam size for internal wall = 125 mm × 200 mm

Overall length for internal wall beam = 140 ft = 42000 mm

Volume = 0.125 × 0.2 × 42 × = 1.05 m3

Total volume = 2.16 + 1.05 = 3.21 m3

6) rcc roof slab = 50′ × 30’×6″

Length of slab = 50 feet

Width of slab = 30 feet

Thickness of slab = 6 inch = 0.5 feet

Volume = 50′ × 30’× 0.5′ = 750 cubic feet

1 m3 = 35.3147 cu ft

Volume = 750/35.3147 = 21.24 m3

Now Total wet volume of concrete required for 1500 square feet house

Footing = 6.48 m3

Column = 9.72 m3

Plinth beam = 8.1 m3

Door beam = 2.4 m3

Roof beam = 3.21 m3

Roof slab = 21.24 m3

Total wet volume of concrete = 51.15 m3

Dry volume of concrete = 51.15×1.54 = 78.77 m3

If we take M20 grade of concrete in which cement sand and aggregate ratio is 1:1.5:3

Cement quantity = (1/5.5)× 78.77 × 1440 kg/m3

Cement weight = 20623 kg

1 cement bag weight = 50 kg

no of cement bags = 20623/50 = 412.5

● **Ans. :-** 412.5 no of cement bags required for RCC concrete structure footing, beam, column & slab for 1500 sq ft house of low rise building of ground floor.

**Cement bags required for brickwork of 1500 square feet house**

Height of brick wall above roof slab = 3 feet

Depth of brick wall below plinth = 2 feet

Total height = 15 feet

Area of external brick wall = 160×15 = 2400 sq ft

Volume = 2400 sq ft × 9 inch = 1800 cu ft

Volume = 1800/35.3147 = 51 m3

Volume of brickwork = 51 m3

thumb rule for cement bags in external wall brickwork is 1.26 cement bags/m3 of brickwork of 9 inch ( cement sand ratio 1:6)

no of cement bags = 51 × 1.26 = 64 bags

2) cement consumption in internal brick wall

brick wall length = 50+30+30+30 = 140 ft

Height of brick wall = 10 feet

Depth of brick wall below plinth = 2 feet

Total height = 12 feet

Area of external brick wall = 140×12 = 1680 sqft

Volume = 1680 sq ft × 4.5 inch = 630 cu ft

Volume = 630/35.3147 = 17.84 m3

Volume of brickwork = 17.84 m3

thumb rule for cement bags in internal wall brickwork is 1.28 cement bags/m3 of brickwork of 4.5 inch ( cement sand ratio 1:4)

no of cement bags = 17.84 × 1.28 = 23 bags

Total no of cement bags = 64 + 23 = 87

● **Ans. :-** 87 no of cement bags required for brickwork of 1500 square feet house

**How many cement bags required for ground flooring of 1500 square feet house.**

In ground flooring we use plain cement concrete m15 grade of concrete in which mix ratio of cement sand and aggregate is 1:2:4 and floor thickness is 6 inch ( 4 inch concrete + 2 inch platering for flooring + tile flooring)

Ground flooring concrete slab = 50′ × 30’×6″

Length of slab = 50 feet

Width of slab = 30 feet

Thickness of slab = 6 inch = 0.5 feet

Volume = 50′ × 30’× 0.5′ = 750 cubic feet

1 m3 = 35.3147 cu ft

Volume = 750/35.3147 = 21.24 m3

Wet volume = 21.24 m3

Dry volume = 21.24 × 1.54 = 32.71 m3

no of cement bags = (1/7) 32.71 × (1440/50)

no of cement bags = 135 bags

● **Ans. :-** 135 no of cement bags required for ground flooring of concrete, plastering of ground flooring and tile flooring of 1500 square feet house

**How many cement bags required for plastering of 1500 square feet house**

1) external plastering of brick wall

Length total = 160 ft

Height = 10 ft

Area of plastering = 160 × 10 = 1600 sq ft

thumb rule for cement bags for external plastering is 0.017017 cement bags/ sq ft plastering

no of cement bags = 1600 × 0.017017 = 27 bags

2) internal plastering of brick wall

Length total = 340 ft

Height = 10 ft

Area of plastering = 340 × 10 = 3400 sq ft

thumb rule for cement bags for external plastering is 0.0086 cement bags/ sq ft plastering
