Q1. What is Full form of SBC
Ans. 
SBC stands for Safe Bearing Capacity.
• SBC is the maximum pressure that can be applied to the soil without risk of shear failure.

• It is an important factor in the design of foundations for structures.

• For example, if the SBC of a soil is 200 kN/m^2, it means that the soil can safely support a load of 200 kN per square meter.

Q2. What is mix of M20 grade of concrete
Ans. 
M20 grade of concrete is a mix of 1:1.5:3 ratio of cement, sand, and aggregate.
• M20 grade of concrete has a compressive strength of 20 MPa after 28 days.

• The mix ratio for M20 grade concrete is 1:1.5:3 (cement:sand:aggregate).

• It is commonly used for residential construction projects like flooring, beams, and columns.

Q2. Different grades of concrete
Ans. 
Different grades of concrete refer to the strength and quality of the concrete mix.
• Different grades of concrete are designated by their strength in megapascals (MPa), such as M20, M30, etc.

• Higher grade concrete has a higher strength and is typically used for structural purposes.

• Lower grade concrete is suitable for non-structural applications like paving or flooring.

• The mix proportions and ingredients vary for different...read more

Q1. What is the grade of concrete
Ans. 
The grade of concrete refers to its strength and is determined by the ratio of cement to sand to aggregate.
• The grade of concrete is typically denoted by a number followed by the letter 'M', such as M20, M30, etc.

• The number in the grade represents the compressive strength of the concrete in megapascals (MPa) after 28 days of curing.

• For example, M20 concrete has a compressive strength of 20 MPa, while M30 concrete has a ...read more
