What is meant by PCC in construction?

PCC. Plain Cement Concrete. Civil Engineering, Water Resources, Cement.

What does PCC stand for construction?

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).

What is meant by PCC concrete?

Plain cement concrete is the mixture of cement, fine aggregate(sand) and coarse aggregate without steel. PCC is an important component of a building which is laid on the soil surface to avoid direct contact of reinforcement of concrete with soil and water.

Why PCC is used in foundation?

The main reason of providing PCC is to provide a rigid impervious bed to RCC in the foundation before starting any RCC or masonry work directly on the excavated soil, PCC is done to form a leveled surface and to avoid laying concrete on soil directly so as to avoid mixing with soil and also to prevent soil extracting ...

Which cement is used for PCC?

Cement: Normally, the Portland cement is utilized as bonding material in PCC. Fine Aggregate: Sand is employed as fine aggregate. The fineness modulus (FM) of sand should remain 1.2 to 1.5.

Civil engineer basic knowledge on Site for PCC work | Plain cement concrete basic knowledge

What is the PCC ratio?

PCC Ratio. PCC concrete mix ratio is 1:5:10, which Means 1 part of cement, 5 parts of sand, and 10 parts of aggregate. PCC in construction is used to make a level bed for footing.

What is the difference between PCC and RCC?

The main difference between PCC and RCC is that RCC contains steel rods or reinforcement within it but PCC does not contain reinforcement within it. So, RCC can bear the maximum tensile load on it.

Is PCC waterproof?

The surface course is the layer in contact with traffic loads and is made of PCC. It provides characteristics such as friction (see Figure 3), smoothness, noise control and drainage. In addition, it serves as a waterproofing layer to the underlying base, subbase and subgrade.

How is PCC area calculated?

Suppose we have project of making concrete pavement of area 100m2 and slab thickness of PCC is 150 mm. Now we have to calculate dry volume calculating dry volume we should multiply a cofactor 1.54 in wet volume. Mix ratio in M15 grade = 1:2:4 one part cement two part is sand and 4 part is aggregate.

Where is PCC and RCC used?

In terms of strength, naturally, RCC is stronger because the reinforcement helps in load-carrying capacity. PCC is weaker and is only used for layering surfaces like plastering work or flooring and most importantly in the layering if excavation to cast footings.

What is PCC floor?

Plain Cement Concrete (PCC) consists of cement, fine aggregate, coarse aggregate and water. ... As bed concrete below the wall footings, column footings and on walls below beams. As sill concrete to get a hard and even surface at window and ventilator sills. As to coping concrete over the parapet and compound walls.

What is RCC and PCC and DPC?

PC – Pile Cap. PC – Precast Concrete. PCC – Plain Cement Concrete. PERT – Programme Evaluation and Review Technique.

What is RCC slab?

A Reinforced Concrete Slab is the one of the most important component in a building. It is a structural element of modern buildings. Slabs are supported on Columns and Beams.

What is RCC road?

Roller compacted concrete (RCC) is a tough, durable type of concrete pavement that is well suited for heavy industrial applications, as well as low-speed roads and arterial roads. Roller compacted concrete draws its name from the construction practices used to place and finish the material.

What is PCC in rigid pavement?

Portland cement concrete (PCC) pavements (or rigid pavements) consist of a PCC slab that is usually supported by a granular or stabilized base, and a subbase. In some cases the PCC slab may be overlaid with a layer of asphalt concrete.

Is PCC required for plinth beam?

The top surface of the P.C.C. confirms the plinth level of the building. After completing the plinth filling with murum and soiling up to the designed level, P.C.C. is to be done.

What is m30 cement?

∴ In the designation of a concrete mix, the letter 'M' and the number stands for Mix and characteristic compressive strength of 150 mm cube at 28 days. ∴ The M 30 grade of concrete means the concrete mix which attains 28 day strength (characteristics) as 30 MPa or 30 N/mm².

What is M20 grade concrete?

M20 signifies mixture of cement, sand and aggregate which are prepared in such a manner that a cement concrete cube of size 15 cm x 15 cm x 15 cm is formed with characteristic strength (fck) of 20mpa while examining it after being cured for 28 days.

What is PCC and RCC ratio?

Concrete mix ratio is used as PCC (plain cement concrete) in Roadways Pathwas formation and for flooring of house and also concrete mix ratio is used as RCC for the formation of roof slab, Foundation, footing, beam and column. PCC ratio for footing:– generally concrete mix ratio used as PCC for footing is 1:3:6 (M10).

How many bags of cement are in one cubic meter of PCC?

Quantity of cement = 1/13 × 1.54 m3 × 1440 kg/m3 = 170 kg, no of bag cement for 1m3 PCC 1:4:8 (m7. 5) = 170/50 = 3.4.

What are the materials used in PCC?

PCC consists of three basic ingredients: aggregate, water and portland cement.

What is plinth level?

plinth level means the level of the floor of a building immediately above the surrounding ground.

What is CC in civil engineering?

Concrete cloth (CC) is a unique proprietary material. It has a very wide range of applications throughout the building & civil engineering industry. Concrete cloth is a flexible; cement impregnated fabric that hardens when hydrated to form a thin, durable, water & fire proof concrete layer.

What is UCR construction?

A typical uncoursed random (UCR) stone masonry wall is illustrated in Figure 1. In many cases, these walls support heavy roofs (for example, timber roof with thick mud overlay). Laypersons may consider such stone masonry buildings robust due to the large wall thickness and robust appearance of stone construction.
