Concrete grades are classifications that indicate the strength and quality of concrete.
Concrete grades are determined based on the compressive strength of the concrete.
The most common concrete grades are M10, M15, M20, M25, M30, M35, M40, M45, M50, M55, M60, and M70.
The number in the concrete grade represents the compressive strength of the concrete in megapascals (MPa).
For example, M20 grade concrete has a compressive...
The density of steel is approximately 7.85 g/cm³.
Density of steel is measured in grams per cubic centimeter (g/cm³).
The density of steel varies depending on the alloy and composition.
The density of stainless steel is around 7.9 g/cm³, while the density of carbon steel is around 7.85 g/cm³.
The density of steel is important in determining the weight and strength of structures made from steel.
Buckling is a phenomenon where a structural member fails due to excessive compressive stress.
Buckling occurs when a slender member is subjected to compressive stress.
It is a sudden failure of the member due to instability.
Buckling can occur in columns, beams, and other structural members.
The critical load at which buckling occurs is dependent on the material properties and geometry of the member.
Examples of buckling in...
The density of cement varies depending on the type of cement being used.
The density of ordinary Portland cement is around 1440 kg/m³.
The density of white cement is around 1300 kg/m³.
The density of rapid hardening cement is around 1250 kg/m³.
The density of low heat cement is around 1200 kg/m³.
The density of high alumina cement is around 1400 kg/m³.

I applied via Naukri.com and was interviewed before Jan 2021. There were 4 interview rounds.
M15 concrete grade refers to the mix ratio of cement, sand, and aggregate used in construction.
M15 concrete grade has a mix ratio of 1:2:4, which means 1 part cement, 2 parts sand, and 4 parts aggregate by volume.
It is commonly used for non-structural components like flooring, pathways, and plastering.
The strength of M15 concrete is 15 megapascals (MPa) after 28 days of curing.
M15 grade is suitable for areas with low l...
The density of steel is approximately 7.85 grams per cubic centimeter.
Density is a measure of how much mass is contained in a given volume.
Steel is a commonly used construction material known for its strength and durability.
The density of steel can vary slightly depending on its composition and specific type.
The density of steel is typically measured in grams per cubic centimeter (g/cm³).
For example, the density of car
The density of RCC (Reinforced Cement Concrete) is typically around 2400 kg/m^3.
RCC is a composite material made of cement, sand, aggregates, and steel reinforcement.
The density of RCC can vary depending on the mix design and the type of aggregates used.
The density is usually measured in kilograms per cubic meter (kg/m^3).
The density of RCC is important for structural calculations and determining the weight of the cons...
The degree of bend for a hook depends on the specific application and requirements.
The degree of bend for a hook is determined by factors such as the load it needs to support, the type of material being hooked, and the desired angle of engagement.
In construction, hooks with a 90-degree bend are commonly used for hanging objects or supporting scaffolding.
For lifting heavy loads, hooks with a larger degree of bend, such ...
Bend deduction is the amount of material that needs to be removed from the total length of a bend to achieve the desired angle.
Bend deduction is calculated based on the material thickness, bend radius, and angle of the bend.
It is used in sheet metal fabrication to determine the length of the flat pattern before bending.
The formula for bend deduction is: Bend Deduction = (0.01745 x Bend Angle x Inside Radius) + (0.0078 ...
