What is the difference between Rbc and Rcc concrete,what is RBC concrete,in this topic know about What is the difference between Rbc and Rcc concrete.
When our brickwall is completed that is proper curing of brickwall is over than seconds questions is arises in our mind for the roof casting which one is better for choosing RBC or RCC concrete.
RBC construction of Roof of building is usually seen in those Areas where the bricks is available in good quality and aggregates or stone chips for concreting is too costly to use.
What is the difference between Rbc and Rcc concrete
■ RCC slab:- RCC is reinforced cement concrete in civil work for making column beam footing and slab. It is used as per design of building structure where Steel bar is required in slab as per spacing.
The reinforcement in steel bar placed at right spacing as per design which depend on the load of slab is required to carry.
■ Rbc slab :– RBC is reinforced brick concrete used for roof of building, the space between the bar is occupied by the brick placed on its, Steel bar are placed between the bricks in both the direction.
RBC is the combination of reinforcements of brick concrete where bricks is only act as filler material which does not help with increase the strength of RCC work for load carrying capacity of slab. So bricks is only act as filler material in RBC slab
What is the difference between Rbc and Rcc concrete
1) extra load is increase in RBC slab due to use of bricks,so self load of RBC slab is more than RCC slab
2) thickness of slab is increase in RBC because of presence of brick , and slab is whenever completed its require plaster cement mortar and damp proof material on the upper surface of roof that’s increase the thickness of RBC slab
but in RCC slab thickness of roof cast is fixed according to design that is 4 to 5 inches thick that’s may not require layer of plaster cement mortar and damp proof material on upper surface of roof
3) strength of RBC slab is much lower than RCC slab because of bricks it’s self does not increased the strength of slab it’s only increase the load. And bond between bricks and concrete in RBC slab is weaker than bond between reinforced and cement mortar in rcc
4) economically ,use of RBC slab is cheaper than use of RCC slab. Average cost in RCC slab per square feet of concrete is about rupees 120 to 135 and average cost in RBC slab per square feet of concrete is about Rupees 90 to 100
5) load carrying capacity of RBC slab is much lower than RCC slab due to weaker Bond between bricks and reinforced and cement mortar
6) Rbc slab is less resistant to earthquake than rcc slab because of present of bricks having weaker bond
7) RBC slab is not act as damp proof course because brick is porous material which absorbs moisture from the air and in rainy season and that moisture is transferred to concrete bonding between reinforced steel and cement mortar that’s leads to break the bond and gradually might be chance of fallen of slab which make hazards for your family members.
but in the case of RCC slab it is also act as damp proof course which does not absorb moisture from the air and in rainy season so their strength is high and not chance of fallen of slab
8) life of rbc slab is lower than life of RCC slab
So I do not recommended you to use RBC slab it should be avoided as it is not recommended by any code of civil work so much better to use RCC slab which should be adopted in civil engineering for building structure and it is economical, require less finishing less maintenance more life and main purpose to safety for your family and for your members.

■ conclusion :- you should use RCC slab for your roof casting of building rather than to use RBC slab for your building
Is the weight of RBC slab less than RCC?
We’re constructing first floor on our 50 years old house which has RBC slab. So should the roof of first floor be RCC, or RBC? (Keeping in mind the weight of both the slabs, and the fact that our house is relatively old, and we don’t want to put excess pressure on our existing RBC slab)
You should put rcc because its load is less then rbc
Can rbc slab weight is more than RCC slab
