AnswersDriveThe mixture of cement, FINE aggregate (sand) and coarse aggregate is called plain cement concrete (PCC) PCC is mainly used for following purposes. 1. It is used as a protective layer for the RCC above so that water from the RCC is not absorbed by the earth below.
What do you mean by RCC?
RCC Stands for Reinforced Cement Concrete. RCC Building Concrete is a mixture of cement (usually Portland cement) can be made into almost any shape and size for the construction of building.
What is RCC road?
Roller Compacted Concrete (RCC) is the optimal pavement construction solution for local streets and roads. In this video, hear how RCC's installation and maintenance costs are lower than asphalt, as it provides for a more durable pavement solution.

What is rich concrete?
A rich mixture contains a high proportion of cement. A lean mixture is a mixture of concrete or mortar with a relatively low cement content. A harsh mixture of concrete is one without mortar or aggregate fines, resulting in an undesirable consistency and workability.

What is the type of cement?
Following are the different types of cement used in construction works.
- Rapid Hardening Cement: Rapid hardening cement is very similar to ordinary portland cement (OPC).
- Low Heat Cement:
- Sulfate Resisting Cement:
- White Cement:
- Portland Pozzolana Cement:
- Hydrophobic Cement:
- Colored Cement:
- Waterproof Portland Cement:

What is the RCC?
Meaning of RCC: The full form of RCC is Reinforced Cement Concrete. Cement concrete is strong in compressive strength but weak in tensile strength. Steel bars used in cement concrete provide good strength to the structure.

What is meant by RCC building?
When we say concrete in the building trade, we actually mean reinforced concrete. Its full name is reinforced cement concrete, or RCC. RCC is concrete that contains steel bars, called reinforcement bars, or rebars.
5
What is blinding concrete used for?
Concrete blinding is the process of pouring a thin layer of concrete over the floor of a new building; this can be over the hardcore or over the foundation itself. The purpose of this is to seal in underlying material and prevent dirt and mud from interfering with the structure.
6
What is the use of plinth beam?
You can see here the beam is constructed at ground level. The void between the foundation and plinth level is filled with compacted soil. Brick or stone masonary is usually constructed below the plinth beam. The plinth beam needs to be strong, but need not be made up of reinforced cement concrete (RCC) all the time.
7
What is the difference between PCC and RCC?
There is one main difference that is Plain Cement Concrete does not carry 'Steel' and Reinforced Cement Concrete carry 'steel' in it. The other differences as follows: PCC is weak in tension loading while strong in compression loading whereas RCC is strong in compression loading as well as tension loading.
8
What is Portland cement used for?
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone.

What is an RCC wall?
Shear wall is made out of RCC only. RCC means Reinforced Cement Concrete. RCC walls could be made either for retaining purpose for forces from other sides like soil, water etc. OR RCC walls could be made for partition purpose. But becomes a cost affair as compare to bricks.
10
What is meant by RCC in civil engineering?
Reinforced Concrete (RC) or Reinforced Cement Concrete (RCC) are one and the same. Don't be confused by the word “cement” in RCC as any concrete comprises of Cement, sand, aggregates and water. RC and RCC are not two different materials but one.

What is the meaning of DPC in building?
A damp-proof course (DPC) is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. A common example is polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary action.
12
What is the use of cement in concrete?
In its simplest form, concrete is a mixture of paste and aggregates. Cement is actually an ingredient of concrete. It is the fine powder that, when mixed with water, sand, and gravel or crushed stone (fine and coarse aggregate), forms the rock-like mass known as concrete.
13
What is a lean mix of concrete?
Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata. This makes it ideal as a base layer where other kinds of concrete are placed on top.
14
What is the main purpose of lean concrete?
Concrete with a low cement content. Main function of the lean concrete is to provide the uniform surface to the foundation concrete and to prevent the direct contact of foundation concrete from the soil. Lean Concrete is used under the foundations.
15
What is reinforced cement concrete?
Reinforced concrete (RC) (also called 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.
16
Why PCC is used?
What it's used for: PCC is a milder version of chromic acid. Essentially, what it does is oxidize alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. Unlike chromic acid, PCC will not oxidize aldehydes to carboxylic acids.
17
What is Portland cement concrete pavement?
Typical concrete is composed of coarse aggregate (crushed stone and gravel), fine aggregate such as sand, portland cement and water. PCC pavements are subject to challenging environments and loads over their lifetimes, so the concrete must be strong and durable, yet cost effective and workable.
