### Concrete Mix Ratio | What Is Concrete Mix Ratio | Types of Standard concrete mixes ratio M30 to M45 grade concrete mix ratio is manual designed. E.g., M45, the quantity of cement, sand (fine aggregate), and coarse aggregate are batched in volume as per the design mix. From the above table till M45 grade, these concrete proportions are called as Nominal mix concrete.

### Understanding Stresses and Modular ratio | RCC Structures Sep 08, 2012 · m=Es/Ec. The modular ratio is not constant for all grades of concrete. It varies with the grade of concrete. Es/Ec is generally not used to calculate modular ratio for reinforced concrete designs. As per IS: 456-1978; m is calculated by the following formula: m = 280/3σ c bc. where, σ c bc = permissible compressive stress in concrete in bending.

### Rate Analysis of RCC (Reinforcement Cement Concrete Aug 27, 2020 · 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. Also, read: What is Bitumen And Bitumens Types. Labour for Rate Analysis of Concrete

### Concrete Mix Design Calculation : M20, M25, M30, M40 Grade The mix calculations per unit volume of concrete shall be as follows: Volume of concrete = 1 m3 Volume of cement = (Mass of cement / Specific gravity of cement) x (1/100) = (382/3.15) x (1/1000) = 0.121 m3 Volume of water = (Mass of water / Specific gravity of water) x (1/1000) = (191/1) x (1/1000) = 0.191 m3

### Different Grades of Concrete and their uses M20 grade concrete, for example is made up of 1 – part cement to 1.5 part s of sand (fine aggregate) and 3 parts aggregate. (gravel/ crushed stone) M grade concrete is measured using a compressive strength ratio of MPa N/mm2 psi (pounds per square inch) M grade concrete is normally defined under two main categories, Nominal and design concrete.
