3/4 of its strength
Em = 700 f 'm for clay masonry per MSJC 1.8.2.2.1fm=???
Load divided by area of load applied (Load per unit area)
Concrete is cheaper. As in cheaper per kilogram, cheaper to "model". Has a relatively high compressive strength
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.
The force required to break concrete depends on various factors such as the type of concrete, its age, and the specific conditions of the concrete. In general, the compressive strength of concrete is measured in pounds per square inch (psi). For typical concrete mixes, the compressive strength can range from about 2,500 psi to over 10,000 psi. Therefore, the force required to break concrete can vary widely, but it typically takes thousands of pounds of force to break through concrete.
M40 is a concrete mix design that typically has a compressive strength of 4,000 psi (pounds per square inch) at 28 days.
For M25 grade concrete the seven days crushing for site condition shall be not less than 67 % of M25, i.e not less than 16.75 N/mm2 But for target strength of M25 for mix design taken i.e for M25 it is 32 and the 7 days strength shall not be less than 22 N/mm2

The modulus of elasticity of concrete is denoted by Ec .Ec = 5000 sqrt fck as per IS standardswhere, fck- The compressive strength of concrete at 28 days in N/mm2 .
Concrete is cheaper. As in cheaper per kilogram, cheaper to "model". Has a relatively high compressive strength
25 denotes the COMPRESSIVE STRENGTH of the mixture. It means 25 N/mm2
Load divided by area of load applied (Load per unit area)
Concrete is cheaper. As in cheaper per kilogram, cheaper to "model". Has a relatively high compressive strength
As per the Indian standard specifications 3495 ,Compressive Strength, Water Absorption, Efflorescence and Dimensions are the tests to be carried out on bricks.
The term "470 c 2000 concrete" typically refers to a specific type of concrete mix, where "470" denotes the compressive strength of the concrete in kilograms per square centimeter (kg/cm²) at 28 days, and "2000" indicates the characteristic strength in terms of a corresponding class or grade. This concrete is designed for structural applications, offering good durability and strength. The numbers suggest it is suitable for medium to high-strength construction projects.
C30 is a type of concrete mix where the "C" stands for compression strength of the concrete after 28 days of curing. It typically has a compressive strength of around 30 megapascals (MPa) or 4350 pounds per square inch (psi). Other mechanical properties such as tensile strength, flexural strength, and modulus of elasticity will vary depending on the specific mix design and curing conditions.
Grade 60 refers to the yield strength of steel reinforcement, indicating it can withstand 60,000 pounds per square inch of stress before deformation. On the other hand, 60 MPa specifies the material's compressive strength in megapascals, showing how much pressure it can resist before breaking. While Grade 60 is a measure of tensile strength, 60 MPa is a measure of compressive strength.
