What is PCC in Construction?
Have you ever visited a working site? If YES! I am sure; you must have heard builders, masons, and engineers talking about PCC. The term is often used in construction and plays a supreme role in the production of the substructure of a building. Today, we will know more about it.
What is PCC?
- PCC in construction refers to Plain concrete cement formed by a fine mixture of cement, concrete, and aggregate without the presence of. It is also known as Cement Concrete.
- The concentration of cement is way lesser than that of other substances.
- The goal is to make a smooth and plain layer of mixing these materials having more quantity of water and concrete.
- It cannot lift heavy loads – the main purpose of adding a coat of PCC is to detach the soil from steel.
5 Main Advantages of Plain Concrete Cement
In construction and the world of civil – builders deal with a variety of materials having different specialties. We make the foundation of a structure even stronger with plain concrete cement. And the process of PCC is done to protect the building from any unfortunate damage, fall, or displacement.
You can understand this by the simple concept of corrosion. Let us discuss the top 5 advantages of PCC in the construction
- The absence of PCC results in the direct contact of the upper soil and the base reinforcement.
- Direct linkage between both the elements can result in various chemical reactions that could eat the iron present at the foundation of a structural building.
- Corrosion can happen anytime and will eat the entire material – the consequences of this practice can be unimaginably dangerous for the safety of the building.
- Direct RCC can weaken the strength of steel and iron.
- To enhance the productivity of each material and substance added during the construction of footing – plain concrete cement must be essentially added.
Materials Used in The Formation of Plain Concrete Cement
So, till now we have discussed many important facts about PCC and now you will read about the specification of such an incredible mixture. Keep reading to know more about the materials that help in making a smooth and thick surface.
- Portland Pozzolana Cement (P.P.C) acts as a bonding material in plain concrete. All the required tests and examinations must be performed before adding them to the mixture.
- Always remember to use PPC as per specifications and in limited quantity to make the resultant layer smooth and a bit rough.
2. Coarse Aggregate
- A clean combination of stones added to the mixture without dust, clay, organic matter, coal residue mica and unwanted particles.
- The size of each stone must be a maximum of 20 mm in size and each stone should be smashed finely for better result.
- Bricks and stones of all kinds can be possibly used for adding extra durability.
3. Fine Aggregate
- Sand is the main ingredient for making a fine aggregate mixture. Remember to use clean, clear, rock-free sand.
- Hard, sharp and angular grains of sand must be passed through a screen of 5mm square mesh.
- Prefer organic sand over sea sand for good mixing.
- For mixing aggregate and cement to plain concrete cement, the portable water having less acidity.
- Water must be free and filtered out from unwanted elements such as oils, solvents, salts, acids, etc.
Steps Need to Follow for Making a Layer of PCC
- Dig a pit with the required depth and height
- Level the sand by using a leveler from all the sides, corners, and bottom.
- Check and examine the soil and fill the gaps – make the surface more even.
- Mix all three elements of PCC in correct proportions and add layer by layer to the pit.
- Try not to exceed the thickness of 150 mm.
- Let it dry for 24-48 hours and continue the further process.
You have studied all significances of having a PCC layer in a building. Plain Concrete Cement is the principle for the foundation of assembling the base of any structure properly. Generally, it ensures the constructer that the understructure of the base is safe and secure with all three elements. Give more attention to the mixing and amount of each material added to the blend.
