The modular ratio is the ratio of the modulus of elasticity of steel to the modulus of elasticity of concrete. For M20 concrete, which typically has a characteristic compressive strength of 20 MPa, the modulus of elasticity is generally assumed to be around 25 GPa. If we consider the modulus of elasticity of steel to be approximately 200 GPa, the modular ratio (n) can be calculated as n = E_steel / E_concrete, resulting in a modular ratio of about 8. This means that the stiffness of steel is roughly eight times that of M20 concrete.
1:1.5:3:0.45 (cement,fine aggregate,coarse aggregate, water cement ratio)
To calculate the amount of sand and metal (aggregate) in M10 and M20 grades of concrete, you first need to determine the mix ratio. M10 is typically a 1:3:6 ratio (cement:sand:aggregate) and M20 is a 1:1.5:3 ratio. For a given volume of concrete, calculate the total parts in the mix, then divide the total volume by the sum of the parts to find the volume of each component. Finally, multiply the volume of sand and aggregate by their respective mix ratios to find the quantities needed.
Mix ratio for M5 concrete is 1:1.5:3compressive strength is 20N/mm2 @ 28 days.1 part of cement, 1.5 part of sand, 3 parts of coarse aggregate.
an m14 is the original gun. the m20 is an updated dmr version.
Klor-con M20 is potassium chloride. It is a mineral supplement.

how much tensile strength of M20 grade concrete at 28 Days
The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.
