The ratio of M25 grade of concrete is 1:1:2.
M25 grade of concrete is a mix of 1 part cement, 1 part sand, and 2 parts aggregate.
The compressive strength of M25 grade concrete is 25 MPa or 3625 psi.
M25 grade of concrete is commonly used in construction of buildings, bridges, and roads.
A raft is a type of foundation that spreads the load of a building over a large area.
Raft foundation is a type of shallow foundation.
It is used when the soil is weak and cannot support the weight of the building.
It consists of a thick concrete slab that extends over the entire area of the building.
The slab is reinforced with steel bars to provide additional strength.
Examples of buildings that use raft foundation includ...
The strength of cube increases with time. Generally, it reaches 70-80% of its final strength after 7 days and 100% after 28 days.
The strength of cube is measured in terms of compressive strength.
After 3 days, the cube will have gained around 40-50% of its final strength.
After 7 days, the cube will have gained around 70-80% of its final strength.
After 14 days, the cube will have gained around 90% of its final strength.

Cement grade refers to the strength and quality of cement used in construction.
Cement grade is determined by the compressive strength of cement mortar cubes after 28 days of curing.
The most commonly used cement grades are 33, 43, and 53, indicating their respective compressive strengths in megapascals (MPa).
Higher cement grades are used for structures that require higher strength, such as bridges and high-rise building...
Yes, the standard size of a concrete cube is 15 cm × 15 cm × 15 cm.
The standard size of a concrete cube is used for testing the compressive strength of concrete.
The cubes are casted and cured for 28 days before testing.
The cubes are tested using a compression testing machine.
The compressive strength of concrete is calculated by dividing the maximum load applied to the cube by the cross-sectional area of the cube.
I applied via Company Website and was interviewed in Sep 2022. There were 2 interview rounds.
Curing is the process of maintaining moisture and temperature conditions for freshly placed concrete to promote its hydration and strength gain.
Curing is essential for the strength and durability of concrete.
It involves keeping the concrete moist and at a proper temperature for a specific period of time.
Curing can be done using various methods such as water curing, membrane curing, and steam curing.
The duration of curi...
The strength of cement depends on its grade and type.
The strength of cement is measured in terms of compressive strength.
The grade of cement determines its strength. Higher the grade, higher the strength.
Type of cement also affects its strength. For example, Portland cement has higher strength than lime cement.
The strength of cement is also influenced by factors such as curing time, temperature, and humidity.
