#### How do you calculate cement sand and aggregate for 1m3?

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.

### What is the ratio of cement sand and aggregate?

Arbitrary Method of Proportioning Concrete – The general expression for the proportions of cement, sand and coarse aggregate is 1 : n : 2n by volume.1 : 1 : 2 and 1 : 1.2 : 2.4 for very high strength.1 : 1.5 : 3 and 1 : 2 : 4 for normal works.1 : 3 : 6 and 1 : 4 : 8 for foundations and mass concrete works.

### How do you calculate M20 grade cement sand and aggregate concrete?

M20 = 1: 1.5 : 3 (C : S : A) M 20 is the grade of concrete which ratio is 1 ratio 1.5 ratio 3 okay, one is cement and 1.5 is sand and 3 is aggregate.

#### How many kg is 1m3 of aggregate?

Aggregates (crushed rock) – 1200 kg – Aggregates directly influence the compressive strength of concrete. In a standard cubic metre of concrete, this amount of crushed rock forms a sturdy framework for the mix, while the size and shape of the aggregates will influence workability.

### How do you calculate aggregates?

3. How are aggregate scores calculated? – Ans. Aggregate scores are calculated by finding the sum of all those subjects whose marks have to be considered, and then dividing the sum by total marks. The final result is then multiplied with 100, which gives the aggregate percentage. Aggregate Percentage= Sum of marks obtained in given subjects X 100 Total marks of those subjects

### How much cement sand aggregate do I need?

So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 27.5 kgs of water to produce M20 grade concrete.

## How do you calculate cement sand and aggregate for M30?

This formula can be used for any grade of concrete mix design. Formula = material weight = material volume x percentage of total volume x material sp. gravity x total volume. Mass of coarse aggregates 20 mm = 0.745 x 0.60 x 0.50 x 2.885 x 1000 = 644.8 Kg.

## What is meant by 20mm aggregate?

Rodi are the coarse aggregates of size 20mm. These are obtained by crushing of rocks, having angular shape and are retained on 20mm sieve while 60-70% of the aggregates pass through the 20mm sieve.

These are classified as uniformly graded aggregates High strength Low slit content Used for concrete mix designs Useful for highly packed reinforced sections Used in RCC structures like the construction of buildings, flyovers etc.

## What is an aggregate of 50%?

Home QnA Home I wanted to know that if 50% marks in aggregate means one has to score 50 % in every subject or 50 %percent total. for example A – 52,B -53,C-43,D-80,

Answers (2) Comments (0) Question cannot be greater than 3000 characters 0 / 3000 Hi Shivani 50 % marks in aggregrate means the overall score should be 50 %. So, In this case 57 & will be considered and not score of individual subjects. Hope it helps 🙂 Comments (3) Comment cannot be greater than characters 0 / 3000 thanks for your response Reply Question cannot be greater than characters 0 / 3000 Reply Question cannot be greater than characters 0 / 3000 shivani Yadav senior secondary with atleast 50% marks. it means whether PCMB every subject must be have score of 50 marks or overall 50 % marks Reply Question cannot be greater than characters 0 / 3000
