What is the weight of a 40×40 concrete slab | concrete slab weight 40×40×3.5 | concrete slab weight 40×40×4 | concrete slab weight 40×40×5 | how much does a 40×40 concrete slab weigh.

Concrete used for casting of slab of different sizes such as 40×40cm, 30×30cm, 50×50cm at 2cm, 3cm, 3.5cm, 4cm, or 5cm.

Concrete uses for construction of residential, commercial and industrial structure, several projects like bridge, dams, reservoir, Highway Roadways driveway, french drainage system, patio, tunnels, base for retaining walls, drain construction, pavement, road, street, walkaway, and used for slab etc.

Concrete ready mix made of blended mix of Portland cement, sand gravel and other approved ingredient in a required proportion to achieve desired strength, concrete slab are used in patio making, walkway, driveway etc.

Ready mix concrete is mixture of Portland cement, sand and aggregate with some admixture like accelerator, reducer, plasticizer. Each ingredients of concrete required in adequate quantities according to achieve targeted compressive strength or design of a concrete structure.

The volume of concrete measured imperial and metric units, like in cubic meters, cubic feet, cubic yards, litres, gallons and cubic inches. Weight of concrete measured in kilograms (kg) and pound (lb) also.

Ready mix concrete can be used for building or repairing foundation walls, fence post, sidewalks, curbs, steps and ramps and for setting posts and others concrete structure like, footing, slab, beam and columns.

Metric density of Mix bag is around 2130 kg / m3 (2110 kg / m3 to 2150 kg / m3) and imperial density is about 133 lbs / ft3 (130 lbs / ft3 to 135 lbs / ft3). Metric density for structure 2300 kg / m3 (2240 kg / m3 to 2400 kg / m3) and for Reinforced concrete (ex slab or counter) 2400 kg / m3 (2300 kg / m3 to 2500 kg / m3).

Weight of concrete slab is determine by multiplying volume and density. Volume of concrete slab is determine by multiplying Length, Width and Thickness in same unit. Density of concrete slab is taken as 2200 kg/m3. In this article we know about what is the weight of a 40×40 concrete slab at 3.5cm, 4cm, or 5cm thickness.

**What is the weight of a 40×40 concrete slab**

The weight of a 40×40 size solid concrete slab is typically about 12.5 kg at 3.5cm thick, 7kg at 2cm thick, 10.5kg at 3cm thick, 14kg at 4cm thick, and 17.5kg at 5cm thick. This weight of a 40×40 concrete slab is determine by multiplying volume and density.

To calculate the weight of a 40×40 concrete slab, convert all dimensions of concrete slab in meters, multiply Length, width and Thickness in meter to get volume of concrete slab in m3. Volume of concrete slab is multiply by density (2200 kg/m3), resulting figure will be your weight of concrete slab in kilograms (kg).

**Weight of a 40×40 concrete slab at 2cm thickness**

● 1) Given: Length = 40cm, Width = 40cm, Thickness = 2cm

● 2) All dimensions in meter, Length = 0.4m, Width = 0.4m, Thickness = 0.02m

● 3) Volume of a 40×40 concrete slab = 0.4 × 0.4× 0.02 = 0.0032m3

● 4) Weight of a 40×40 concrete slab at 2cm thickness = 0.0032× 2200 = 7 kg approx.

**Weight of a 40×40 concrete slab at 3cm thickness**

● 1) Given: Length = 40cm, Width = 40cm, Thickness = 3cm

● 2) All dimensions in meter, Length = 0.4m, Width = 0.4m, Thickness = 0.03m

● 3) Volume of a 40×40 concrete slab = 0.4 × 0.4× 0.03 = 0.0048m3

● 4) Weight of a 40×40 concrete slab at 3cm thickness = 0.0048× 2200 = 10.5 kg approx.

● 2) All dimensions in meter, Length = 0.4m, Width = 0.4m, Thickness = 0.035m

● 3) Volume of a 40×40 concrete slab = 0.4 × 0.4× 0.035 = 0.0056m3

● 4) Weight of a 40×40 concrete slab at 3.5cm thickness = 0.0056× 2200 = 12.5 kg approx.

**Weight of a 40×40 concrete slab at 4cm thickness**

● 1) Given: Length = 40cm, Width = 40cm, Thickness = 4cm

● 2) All dimensions in meter, Length = 0.4m, Width = 0.4m, Thickness = 0.04m

● 3) Volume of a 40×40 concrete slab = 0.4 × 0.4× 0.04 = 0.0064m3

● 4) Weight of a 40×40 concrete slab at 4cm thickness = 0.0064× 2200 = 14 kg approx.

**Weight of a 40×40 concrete slab at 5cm thickness**

● 1) Given: Length = 40cm, Width = 40cm, Thickness = 5cm

● 2) All dimensions in meter, Length = 0.4m, Width = 0.4m, Thickness = 0.05m
