Cement Concrete Calculation

Cement Concrete Volume

= Length \times Width \times Depth

= 10.00 \times 7.00 \times 4.00

= 280.00 m^{3}

= 9888.12 {ft}^{3}

Wet Volume of Mix

= Total Volume + (Total Volume \times \frac{52.4}{100})

= 280.00 + (280.00 \times \frac{52.4}{100})

= 426.72 m^{3}

Wet volume of mix is 52.4 % higher than dry volume

Amount of Cement Required

Cement Volume

= \frac{Cement Ratio}{Sum of Ratio} \times Wet Volume of Mix

= \frac{1}{5.5} \times 426.72

= 77.59 m^{3}

No. of Cement Bags

= \frac{Cement Volume}{0.035}

= \frac{77.59}{0.035}

= 2216.73 Bags

Cement in Kg

= No. of Cement Bags \times 50

= 2216.73 \times 50

= 110836.36 kg

Note: 1 Bag of cement = 0.035 m³.
1 Cement bag contains = 50 kg cement

Amount of Sand Required

Sand Volume

= \frac{Sand Ratio}{Sum of Ratio} \times Wet Volume of Mix

= \frac{1.5}{5.5} \times 426.72

= 116.38 m^{3}

Sand in Kg

= Sand Volume \times 1550

= 116.38 \times 1550

= 180386.18 kg

Sand in Ton

= \frac{Sand in Kg.}{1000}

= \frac{180386.18}{1000}

= 180.39 Ton

Note: By considering dry loose bulk density of sand = 1550 kg/m³.
1000 kg = 1 Ton

Amount of Aggregate Required

Aggregate Volume

= \frac{Aggregate Ratio}{Sum of Ratio} \times Wet Volume of Mix

= \frac{3}{5.5} \times 426.72

= 232.76 m^{3}

Aggregate in Kg

= Aggregate Volume \times 1350

= 232.76 \times 1350

= 314221.09 kg

Aggregate in Ton

= \frac{Aggregates in Kg.}{1000}

= \frac{314221.09}{1000}

= 314.22 Ton

Note: By considering dry loose bulk density of aggregate = 1350 kg/m³.
1000 kg = 1 Ton

What is PCC (Plain Cement Concrete) Calculation?

The term PCC stands for plain cement concrete. The mixture of cement, fine aggregate (sand) and coarse aggregate are generally called plain cement concrete (PCC).

Plain Cement Concrete (PCC) is also called as Cement Concrete (CC) or Blinding Concrete. It is used for leveling, bedding for footings, grade slabs, concrete roads etc. PCC is used to provide non-porous, rigid, impervious, firm and leveled bed for laying RCC, where earth is soft and yielding. PCC can be use over brick flat soling or without brick flat soling. PCC also used as filler like lump concrete; this is a mix of PCC and boulder. It consists of cement, sand and coarse aggregates mixed with water in the specified proportions.

Concrete code and Concrete ratio:

Concrete Grade	Proportion of Cement : Sand : Stone pieces	Expected Compressive Strength at 28 days
M10 or M100	1 : 3 : 6	10 N/mm² or 100 Kg/cm²
M20 or M200	1 : 2 : 4	15 N/mm² or 150 Kg/cm²
M20 or M200	1 : 1.5 : 3	20 N/mm² or 200 Kg/cm²
M25 or M250	1 : 1 : 2	25 N/mm² or 250 Kg/cm²

Strength of PCC (Plain Cement Concrete)/Nominal Mix:

Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm² (n/mm² must be read as ‘Newton’s per millimeter Cubic’) compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8. As strength is not a major criterion, the design mix is generally avoided.

What is RCC calculation?

The term RCC stands for Reinforced cement concrete. The mixture of cement, fine aggregate (sand) and coarse aggregate and reinforcement to increase its compressive and tensile strength are generally called Reinforced cement concrete (RCC).

Reinforced cement concrete or RCC is a composite material in which concrete’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed (concrete in compression, reinforcement in tension), so as to improve the behavior of the final structure under working loads.

A lot of variety exists in RCC and there are different types of RCC:

Footing (Pedastal footing, Raft footing, slop footing)
Column
Beam
Slab
Lintle

Strength of RCC/nominal mix:

Strength of RCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm² (n/mm² must be read as ‘Newton’s per millimeter Cubed) compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8. As strength. RCC or Reinforced Cement Concrete is strengthening of Cement concrete by adding mild steel bars in it. There are two types of steel bar; round and torsion. The various elements of RCC construction are foundation, beam, column and slab. These can be prepared by mixing a right proportion of cement, sand, gravel with water and steel bars.

Architects refer the following concrete code table in drawing. Knowing this table will help you in deciding the proportion of cement, sand and gravel in RCC.

Concrete code and concrete ratio

Concrete grade	Proportion of cement : sand : stone pieces	Expected compressive strength at 28 days
M10 or M100	1 : 3 : 6	10 N/mm² or 100 Kg/cm²
M15 or M150	1 : 2 : 4	15 N/mm² or 150 Kg/cm²
M20 or M200	1 : 1.5 : 3	20 N/mm² or 200 Kg/cm²
M25 or M250	1 : 1 : 2	25 N/mm² or 250 Kg/cm²

What are the important RCC?

The RCCs pose the risks related to falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment. Trench collapses cause dozens of fatalities and hundreds of injuries each year. Hence, employer needs to follow strict RCC Rule to ensure safety of the workers in RCC process.
