PCC 1:3:6 refers to the mix of 1 part cement, 3 parts fine aggregates, and 6 parts coarse aggregates, while M10 represents the compressive strength of the concrete after 28 days of curing. In this article, we will delve into the details of cement consumption in PCC 1:3:6 and M10, exploring its composition, properties, and factors affecting its usage. Understanding the dynamics of cement consumption in these grades

## Cement consumption in PCC 1:3:6 and M10

Cement consumption is a crucial factor in the construction industry, as it determines the strength and durability of concrete structures. In this article, we will discuss the cement consumption in two popular types of concrete mix – PCC 1:3:6 and M10.

PCC (Plain Cement Concrete) 1:3:6 is a type of concrete mix that is commonly used as a leveling course for the foundation of buildings, roads, and pavements. It consists of one part cement, three parts sand, and six parts coarse aggregates (usually gravel or crushed stones). The proportions of these ingredients are measured by volume.

The cement consumption in PCC 1:3:6 is calculated based on the volume of concrete required for a specific area. For instance, if we need to construct a 10-meter long and 5-meter wide pavement with a thickness of 150 mm, the volume of concrete required will be:

Volume of concrete = Length x Width x thickness = 10m x 5m x 0.15m = 7.5 m³

Now, the proportion of cement in PCC 1:3:6 is 1:3:6, which means for every 1 part of cement, we need 3 parts of sand and 6 parts of coarse aggregates. Therefore, the cement required for this volume of concrete will be:

Cement consumption = 1/10 x 7.5 m³ = 0.75 m³

Considering the density of cement (1440 kg/m³), the weight of cement required will be:

Weight of cement = 0.75 m³ x 1440 kg/m³ = 1080 kg

Thus, for constructing a 10-meter long and 5-meter wide pavement with a thickness of 150 mm, we would need 1080 kg or 1.08 tons of cement.

Moving on to M10 concrete, it is a type of mix that has compressive strength of 10 MPa (Megapascals) after 28 days of curing. This mix is commonly used for non-structural work such as plastering, brickwork, flooring, etc. The proportions of M10 mix are:

Cement: Fine Aggregates: Coarse Aggregates = 1:3:6 (by mass)

Since M10 mix considers the weight of the ingredients, the calculation of cement consumption is done in terms of weight. The standard weight of a bag of cement is 50 kg, therefore:

Weight of cement required = (1/10) x (50 kg) = 5 kg

Thus, for constructing 1 m³ of M10 concrete, we will need 5 kg of cement. Similarly, for constructing 10 m³ of M10 concrete, we would need 50 kg x 10 = 500 kg or 0.5 tons of cement.

In conclusion, the cement consumption for PCC 1:3:6 and M10 can be calculated based on the volume of concrete or by weight of ingredients, respectively. It is essential to accurately determine the required amount of cement to ensure the structural integrity and longevity of the concrete structures.

## Cement consumption in PCC 1:3:6

Cement consumption in PCC 1:3:6 refers to the amount of cement that is used in the construction of Plain Cement Concrete (PCC) with a mix ratio of 1 part cement, 3 parts coarse aggregates, and 6 parts fine aggregates. PCC is a widely used construction material for building foundations, pavements, and floors.

The mix ratio of 1:3:6 indicates the volume or weight proportion of each component in the concrete mixture. In this case, for every 1 part of cement, there are 3 parts of coarse aggregates and 6 parts of fine aggregates. This mix ratio is considered to be a standard ratio for PCC and is commonly used in construction projects.

The amount of cement consumption in PCC 1:3:6 depends on various factors such as the type and quality of cement, the water-cement ratio, the size and grading of aggregates, and the construction method.

In general, the amount of cement in PCC 1:3:6 is around 300 to 350 kg/m3. This means that for a 1 cubic meter of PCC 1:3:6, approximately 300 to 350 kg of cement is required. This amount may vary depending on the factors mentioned above.

Cement is a binding material that provides strength and durability to the concrete mixture. It reacts with water to form a paste that binds the aggregates together, creating a solid and strong concrete structure. Therefore, the correct amount of cement is crucial in PCC 1:3:6 to ensure the proper strength and durability of the concrete.

Excess cement consumption in PCC 1:3:6 can lead to cracks and shrinkage, while insufficient cement can result in a weak and porous structure. Thus, it is essential to use the correct amount of cement to achieve the desired strength and durability of the PCC.

In conclusion, cement consumption in PCC 1:3:6 is around 300 to 350 kg/m3, which is a standard mix ratio used in construction. It is crucial to use the correct amount of cement to ensure the structural integrity and longevity of the PCC. As a civil engineer, it is essential to carefully calculate and monitor the cement consumption during construction to achieve the desired strength and durability of the PCC.

## Sand quantity consumption in PCC 1:3:6

Sand quantity consumption in PCC 1:3:6 refers to the amount of sand required in the construction of Plain Cement Concrete with a mix ratio of 1 part cement, 3 parts fine aggregate (usually sand), and 6 parts coarse aggregate (usually gravel or crushed stone). PCC is commonly used in the foundation, flooring, and pavement of buildings, roads, and other structures.

The purpose of sand in PCC 1:3:6 is to fill the voids between the coarse aggregates and bind all the materials together to form a strong and durable concrete. The amount of sand required in this mix depends on various factors, such as the size and shape of the coarse aggregates, water-cement ratio, and the desired strength of the concrete.

Generally, it is recommended to use clean, sharp, and well-graded sand in PCC 1:3:6. The sand should pass through a 4.75 mm sieve and not have a high percentage of silt or clay content. The presence of excessive silt or clay particles can affect the workability and strength of the concrete.

The sand quantity consumption in PCC 1:3:6 is determined by the volume of sand required for a given volume of concrete. The volume of sand is calculated by multiplying the area of the concrete by the thickness and then by 3 (as the mix ratio is 1:3, i.e., 3 parts of sand for 1 part of cement). The required volume of sand can also be calculated by using the standard quantity of sand per bag of cement, which is approximately 1.25 cubic feet.

For example, if we need to construct a floor of 1000 square feet with a thickness of 4 inches (0.33 feet), the required volume of sand would be 1000 x 0.33 x 3 = 990 cubic feet. This translates to approximately 792 bags of cement (990/1.25) for the given volume of sand.

However, it is important to note that the sand quantity consumption in PCC 1:3:6 may vary depending on the specific conditions of the project. The volume of sand required may increase if the coarse aggregates are large or have irregular shapes, as more sand would be needed to fill the gaps. Similarly, a lower water-cement ratio would require more sand to attain the desired workability and strength of the concrete.

In conclusion, the sand quantity consumption in PCC 1:3:6 is an important aspect to consider in the construction of concrete structures. It is essential to use the right type and amount of sand to ensure a strong and durable concrete that can withstand the loads and environmental factors. Proper supervision and testing should be carried out to ensure that the correct amount of sand is being used in the construction process.

## Aggregate quantity consumption in pcc 1:3:6

Aggregate quantity consumption is an essential aspect of any civil engineering project, especially when it comes to the construction of plain cement concrete (PCC) structures. PCC 1:3:6 is a commonly used mix ratio for concrete, where one part of cement is mixed with three parts of fine aggregate (sand) and six parts of coarse aggregate (crushed stone) by volume.

The first step in calculating the aggregate quantity consumption for PCC 1:3:6 is to determine the total volume of concrete needed for the project. This can be calculated by multiplying the length, width, and height of the area where the concrete will be laid. For example, if the area is 10 feet long, 8 feet wide, and 6 inches deep, the volume of concrete needed will be 40 cubic feet (10 x 8 x 0.5).

Next, we need to determine the quantity of cement required. Since the mix ratio is 1:3:6, the volume of cement needed will be one-fourth of the total volume of concrete. In this case, it will be 10 cubic feet (40/4). As one bag of cement contains 1.25 cubic feet of volume, the total number of bags needed will be 8 (10/1.25).

After calculating the cement quantity, the focus shifts to the fine aggregate. In PCC 1:3:6, the amount of fine aggregate is three times that of cement. Therefore, for 10 cubic feet of cement, we will need 30 cubic feet of fine aggregate. Again, as a rule of thumb, it is recommended to use a sand to cement ratio of 2:1. Hence, we will need 60 cubic feet of sand (30 x 2).

Lastly, we need to calculate the quantity of coarse aggregate. In PCC 1:3:6, the quantity of coarse aggregate is six times that of cement. Therefore, we will need 60 cubic feet of coarse aggregate for 10 cubic feet of cement. The size of the aggregate used will depend on the thickness of the concrete layer. For a 6-inch PCC layer, aggregates of size ranging from 6 to 10 mm are suitable.

In summary, for PCC 1:3:6, the aggregate quantity consumption is eight bags of cement, 60 cubic feet of sand, and 60 cubic feet of coarse aggregate per 40 cubic feet of concrete. It is important to note that these calculations are based on the proportions specified in the mix ratio. Any deviation from the mix ratio will require a re-calculation of the aggregate quantities.

In conclusion, understanding the aggregate quantity consumption in PCC 1:3:6 is crucial for a civil engineer to effectively plan and execute a project. Proper calculation and utilization of the aggregate materials will result in a strong and durable PCC structure.

## Water cement ratio for m10 grade of concrete

Water cement ratio (w/c) is an important parameter in the design of concrete mix for any grade of concrete. In this article, we will discuss the water cement ratio for M10 grade of concrete.

M10 grade of concrete is the lowest grade of concrete with a compressive strength of 10 MPa or 1450 psi. It is generally used in non-structural and low load-bearing applications such as flooring, foundation, and plastering.

The water cement ratio for M10 grade of concrete is the ratio between the weight of water to the weight of cement used in the concrete mix. It is denoted by “w/c”. For example, if we use 0.45 m3 of water and 1 m3 of cement for making 1 m3 of concrete, then the water cement ratio would be 0.45.

The water cement ratio for M10 grade of concrete varies between 0.5 and 0.6, depending on the design mix requirements. However, the most commonly used water cement ratio for M10 grade of concrete is 0.55. This means for every 1 kg of cement, 0.55 kg of water is used.

The water cement ratio for M10 grade of concrete is kept relatively higher than higher grades of concrete (such as M20, M25, etc.) to ensure better workability and to compensate for the lower strength of the mix. The higher water content also helps in better hydration of cement, resulting in better strength development.

It is to be noted that the water cement ratio should not be too high as it can lead to segregation and bleeding in the concrete mix. It can also result in lower strength and durability of the concrete. On the other hand, if the water cement ratio is too low, it can result in lower workability and difficult placement of the concrete.

Therefore, the water cement ratio for M10 grade of concrete should be carefully selected and fine-tuned to achieve the desired workability and strength of the mix. It is recommended to conduct trials and tests with different water cement ratios to find the optimum ratio for a specific grade of concrete.

In addition to the water cement ratio, other factors such as the quality of materials, curing conditions, and mix proportions also play a crucial role in determining the strength and durability of the concrete. These factors should be carefully considered and controlled during the construction process.

In conclusion, the water cement ratio for M10 grade of concrete plays a significant role in determining the workability, strength, and durability of the concrete. It should be carefully selected and fine-tuned to achieve the desired properties of the concrete. Proper quality control and construction practices should also be implemented to ensure the best performance of the concrete.
