RCC stands for Reinforced Cement Concrete, the most integral structural element of Civil Engineering in 21th Century. RCC has taken the world to new heights of development in commercial and residential construction. What is Reinforced ?According to the Oxford Dictionary Reinforced meaning is “MAKE IT STRONGER.” So we make the concrete with steel bars to become strong

Min Grade of concrete for RCC: there are different grade of concrete used as RCC is M20, M25, M30, M35, M40, M50, etc. Which is the minimum grade of concrete used for RCC? ans. The minimum grade of concrete used for RCC is M20, with ratio 1:1.5:3 means 1 part of cement, 1.5 parts of fine aggregate (sand) and 3 parts of coarse aggregate.

What is the minimum grade of concrete for RCC work? ans. The minimum grade of concrete used for RCC is M20, with ratio 1:1.5:3 means 1 part of cement, 1.5 part of fine aggregate (sand) and 3 part of coarse aggregate.

What is the minimum grade of concrete for RCC slab? ans. The minimum grade of concrete used for RCC slab is M20 & M25. M20 concrete with ratio 1:1.5:3 means 1 part of cement, 1.5 part of fine aggregate (sand) and 3 part of coarse aggregate & M25 concrete with ratio 1:1:2 means 1 part of cement, 1 part of fine aggregate (sand) and 2 part of coarse aggregate.

What is the minimum grade of concrete for RCC beam? ans. The minimum grade of concrete used for RCC beam is M20 & M25. M20 concrete with ratio 1:1.5:3 means 1 part of cement, 1.5 part of fine aggregate (sand) and 3 part of coarse aggregate & M25 concrete with ratio 1:1:2 means 1 part of cement, 1 part of fine aggregate (sand) and 2 part of coarse aggregate.

What is the minimum grade of concrete for RCC work?

What is the minimum grade of rcc concrete for hydraulic structure (sea exposed)? Ans. The minimum grade of concrete used for Hydraulic structures for sea exposed condition min Grade of RCC concrete is M35

What is the minimum grade of rcc concrete for full submerged in sea water? Ans. The minimum grade of concrete used for hydraulic structure full submerged or partially submerged structures min Grade of RCC concrete is M40.

Minimum grade of concrete used in RCC as per IS 456: 2000– According to IS 456:2000 recommended that minimum Grade of concrete used for RCC is not less than M20. This is the minimum grade of concrete for RCC with ratio 1:1.5:3 means 1 part of cement,1.5 parts of fine aggregate (sand) and 3 parts of coarse aggregate.

Minimum grade of concrete used in sea water :– in sea coast or sea water a hydraulic structures, sea exposed condition for moderate climate, minimum grade of concrete used in RCC is M35 and for full submerged or partially submerged structures in sea water minimum Grade of RCC concrete used is M40.

Minimum grade of rcc concrete for water tank:- for water tank minimum Grade of rcc concrete is taken as M30, as minimum grade of concrete for RCC structures is M30 as per IS: 3370 (Part1) 2009.

Minimum grade of concrete used in prestressed concrete:- minimum grade of concrete used in prestressed concrete is M30 ,The prestressed structures are generally prestressed even before the 28th day to speed up the process. A high-grade mix concrete will develop greater strength before 28 days when compared to an M20 mix.

Minimum grade of concrete in post tension:- A minimum of M30 grade of concrete is required for post-tension. Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed.

Minimum grade of concrete in pre tension:– A minimum grade of concrete is M40 for Pre tensioning. The reason Pretensioned members require high strength is that in the pre-tensioned system the casting process is very long.
