how much tensile strength of M20 grade concrete at 28 Days
Concrete with a compressive strength of 3500 psi is typically classified as a Grade 25 concrete, according to the American Concrete Institute (ACI) standards. This strength is commonly used for residential applications, such as driveways, sidewalks, and foundations. It provides a good balance of strength and workability for various construction projects.
Concrete with a grade of M10 typically has a compressive strength of around 2500 psi. This mix generally consists of a ratio of 1 part cement, 3 parts sand, and 6 parts aggregate (1:3:6). M10 is considered a low-strength concrete, often suitable for non-structural applications such as leveling or bedding. For higher strength requirements, higher-grade mixes like M20 or M25 would be more appropriate.
C20 grade concrete has a characteristic compressive strength of 20 megapascals (MPa), which is approximately 2,900 pounds per square inch (psi). This grade is commonly used for structural applications that require moderate strength, such as pavements, slabs, and foundations. The mix typically consists of a specific ratio of cement, aggregates, and water to achieve this strength.
500psi
It is exactly 4351 psi but generally referred to as 4500 psi.

C25 concrete is a concrete having compressive strength of 25MPa when tested at the 28th day after casting. The specimen can be cube(150x150x150) or cylindrical(125mm by 250mm high). The cube strength has 0.8 times that of cylindrical specimen due to shape factor.

3000 psi concrete weighs Approx 3900 Lb/yd3
Proportions for different grades: Cement : Sand : Gravel 1 : 2 : 5 for grade C15(general purpose concrete) 15 mpa 1 : 2 : 4 for grade C25(strong) 25 mpa 1 : 2 : 3 for grade C30(very strong) 30 mpa Remember the proportion is done in terms of volume. This means the above proportions are correct if using the same measure.
Concrete 3000 psi means that the concrete has a compressive strength of 3000 pounds per square inch (psi). This measurement indicates how much pressure the concrete can withstand before cracking or breaking. A higher psi value generally means stronger and more durable concrete.
