## Rate Analysis of RCC (Reinforcement Cement Concrete)

Rate analysis of RCC (Reinforcement Cement Concrete) used for reference book IS Code 1200 part 2 (IS Code 1200 part 2 used for measurement), IS Code 2212, and CPWD Part 1.

All calculations of Reinforcement Cement Concrete for rate analysis. This calculation calculates of cement, sand, Aggregate, and Reinforcement (RCC = Cement + Sand + Aggregate + Reinforcement mixture this call RCC) for materials.

RCC is used a sum different proportions 1:0.5:1, 1:1:2, 1:1.5:3, 1:2:4, 1:3:6 etc.(1 cement: 1.5 Sand: 3 Aggregate). This quantity estimation of RCC is required for the rate analysis.

## Important Point in Rate Analysis of RCC (Reinforcement Cement Concrete)

### Measurement of RCC (Reinforcement Cement Concrete):

Unless otherwise stated, all work shall be measured net in the decimal system as fixed in its place as given in below point no 1. to below point no 3. Any work is done extra over the specified dimensions shall be ignored.

1. Dimensions shall be measured to nearest 0·01 m except for the thickness of slab which shall be measured to nearest 0·005 m,
2. Areas may be worked out to the nearest 0·01 square meter.
3. Cubic contents shall be worked out to the nearest 0·01 cubic meter.

Dimensions– In booking dimensions, the order shall be consistent and generally in a sequence of length, width, and height or depth or thickness.

### Dednctioan of RCC (ReinforcementFr Cement Concrete):

Ends of dissimilar materials, for example, beam, ports, girders, purlins, trusses, corbels, and steps up to 500 cm2 in cross-section.

Opening up to 0.1 m2 or as specified.

The volume occupied by reinforcement.

The volume occupied by pipes, conduits, sheathing, etc., not exceeding 100 cm2 each in cross-sectional area or as specified.

Small voids, such as the shaded portions in as per below fig., when these do not exceed 40 cm2 each in cross-section.

Stops, miters, returns, rounded ends, junctions, dishing, etc., in connection with linear or super labors,

Note: In calculating the area of an opening. The thickness of any separate lintel or sill shall be included in the height. No extra labour for forming such an opening or voids shall be measured.

### Work to be Measured Separately

Rate analysis of RCC of the different area and location rate analysis different executed in the following conditions shall be measured separately:

• Work in or underwater,
• Work in liquid mud,
• Work in or under foul situations,
• Work under tides and
• Work in snow.

### Material calculation in Rate Analysis like Cement, sand, aggregate, and reinforcement

#### Cement calculation

Dry Cement volume = 1.25 convert Wet cement.(The concrete mortar dry volume of concrete decrease volume of dry cement mortar, so 1.25 time of dry mortar)

Wastage of cement mortar 30 % (1.25) extra

So, Cement calculation requirement of cement = 1 x 1.25 x 1.30 = 1.625 cu.m,

Herer calculation concrete ratio 1:1.5:3

The required amount of Cement quantity at concrete = 1.625 Cu.m. x (1/(1+1.5+3))

• = 1.625 x 0.1819
• = 0.2956 cu.m. cement requirement
• Cement in k.g. = volume x density cement
• Cement in k.g. = 0.2956 cu.m. x 1440 (1440 kg/m Density of cement for 50 k.g)
• = 0.2956 x 1440 = 425.646 kg of cement of bag requied ment of cement in k.g.
• = 425.646 / 50 (one cemnent bag weight 50 k.g. only) = 8.51 bag
• So, 10 cu.m. concrete requirement of cement = 8.52 bag x 10 cu.m. = 85.20 bag

#### Sand calculation

• Required amount of Sand = 1.625 Cu.m. x (1.5/(1+1.5+3))
• =0.443 Cu.m. requierd of sand for 1 Cu.m.
• So,
• 10 cu.m. concrete requirement of sand = 0.443 Cu.m x 10 cu.m. = 4.43 cu.m.

#### Aggregate calculation

• The required amount of Aggregate
• = 1.625 Cu.m. x (3/(1+1.5+3))
• =0.90 Cu.m. required of sand for 1 Cu.m.
• So,
• So, 10 cu.m. concrete requirement of sand = 0.90 Cu.m x 10 cu.m. = 9.0 cu.m.
• Two types of aggregate like 20 mm & 10 mm size. this ratio 60 % of total aggregate 20mm size, 40 % of total aggregate 20mm size
• 20 mm aggregate = 9.0 cu.m. x 60% = 5.4 cu.m. 20 mm size aggregate
• 10 mm aggregate = 9.0 cu.m. x 40% = 3.6 cu.m. 20 mm size aggregate

#### Reinforcement calculation

• Assume of reinforcement 2% of the total volume of concrete.
• so,
• 1 cu.m. concrete for reinforcement = 1.0 x 2% = 0.02 ton of steel (this 2% only assumse as per exprience)
• Her, 10 Cu.m concrete requirement = 0.02 ton x 10 co.m. =0.20 ton = 200 kg for 10 cu.m.

Aw, this was a very nice post. In thought I wish to put in writing like this moreover – taking time and actual effort to make a very good article… but what can I say… I procrastinate alot and on no account appear to get something done.
