What is PCC in Construction

     Hi there, Welcome to " www.thecivilengineer18.com ", I constantly update myself, so I want my reader to do the same. So check out my website regularly for construction, Business and Finance updates.

    In this article/ post, I will explain what PCC is in construction.

What is PCC in Construction

What is the abbreviation?

    PCC means Plain Cement Concrete, which denotes no reinforcement(Steel) included in the concrete. If you use Reinforcement within the Concrete it will become RCC.

Where is it Used? 

    PCC was mostly used in places of High Compression with negligible or no tension at all. For example, they are used to make flooring after the soil filling is done in the basement of a building to provide and strong platform for the laying of tiles/ Marble or any kind of flooring in the sequence of construction of a building. 

    They are also used to provide a bed for the RCC structure from direct contact with the soil to provide a uniform platform for the Structures like the Footing of the building.

What is the Grade/ Ratio of PCC?

    PCC usually has a ratio of 1:2:4 - Where Everyone parts Cement, 2 Parts of sand and 4 parts of Aggregate which is usually 12 to 20mm used. Mostly it is 20mm ( in local terms it is known as 1 1/2 inch jally). 

How much Material will be required for the PCC?

    The Material Calculation is a complex process I will tell you how much cement, M. sand/ Sand and Aggregate is needed for 1cum of  PCC concrete. The Following amount of  Material is required,

1. Cement - 4.8 bags 
2. M.Sand / Sand - 0.22 cum 
3. Aggregate - 0.44 cum

How Much Labour Will be Required for PCC Work?

    Labour always depends on the lead i.e. the distance between the material and the actual area of work and also the efficiency of the labour that you employ. so I will give you a rough figure on how much labour will be required. but this will slightly change according to place. Not too much of a difference but a slight difference. 

By Hand Mix,

    The below labour calculation is for the PCC of 1 cum, Including mixing(by Hand), pouring, Consolidating and Curing,

1. Mason - 0.17 Nos
2. MC - 2.33 Nos
3. FC - 0.8 Nos

By Machine Mix

    In Case of Mixer machine is used then, the labour force required to complete 1 cum of concrete will be, including Mixing, Pouring, Consolidating and Curing

1. Mason - 0.17 Nos
2. MC - 1.83 Nos
3. FC - 0.80 Nos
4. Mixer Operator - 0.07 Nos
5. Mixer - 0.07 Nos
6. Vibrator - 0.07 Nos

By using RMC,

    In the Case of Using RMC without Boom, the Labour Force required  to complete 1 cum of concrete will be, including Pouring, Consolidation and curing,

1. Mason - 0.17 Nos
2. MC - 1.83 Nos
3. FC - 0.80 Nos
4. Vibrator - 0.07 Nos

Rate Analysis

    Since we have all the required data we can easily calculate the rate per cum of PCC for the construction process. I am now, mentioning below the current market rate of my place. This may slightly change to your location / Country based on the availability of Materials and labour demand. But the Material required and Labour needed will be the same. Hence for Completing 1 cum of PCC,

1. By Hand - 3807/cum ( For Project) and  Rs. 4256 / cum ( for Individual own house)
2. By Mixer Machine - 3851/cum (For Project ) and Rs. Rs.4314 / Cum ( For Individual Own House)
3. By RMC(without Boom) - Rs.5950/ Cum ( For Project) and Rs.6654 / Cum ( For Individual Own house)

Conclusion 

    So PCC which is Plain cement concrete without reinforcement, is very essential and it is used in the process of providing a segregating layer for the footing and the soil also it is used to get the right floor in the basement / Ground floor for the laying of tiles/ Marbles. They are also used in the construction of pavement in some areas. Hope this will be useful for you. See you in the next article.
