Cement finesse test measures the particle size of cement. Initial and final setting time tests measure the time taken for cement to set.
For cement finesse test, a sample of cement is sieved through a standard sieve and the residue is weighed.
The residue is then sieved through a finer sieve and the weight of the residue is again measured.
The difference between the two weights gives the fineness of cement.
For initial and...

Types of columns include reinforced concrete columns, steel columns, composite columns, and wooden columns.
Reinforced concrete columns are commonly used in building construction for their strength and durability.
Steel columns are often used in industrial structures due to their high load-bearing capacity.
Composite columns combine materials like steel and concrete for optimal performance.
Wooden columns are used in tradi...
Types of slabs include one-way slab, two-way slab, flat slab, and ribbed slab, each used for different purposes.
One-way slab: used for small spans and supported on two opposite sides.
Two-way slab: used for larger spans and supported on all four sides.
Flat slab: used for heavy loads and provides more flexibility in design.
Ribbed slab: used for longer spans and reduces the weight of the slab.
I applied via Approached by Company and was interviewed in Mar 2023. There were 2 interview rounds.
TMT stands for Thermo-Mechanically Treated reinforcement bars used in construction.
TMT bars are made by subjecting mild steel bars to a combination of heat treatment and mechanical deformation.
This process imparts greater strength and ductility to the bars, making them ideal for use in construction.
TMT bars are widely used in reinforced concrete structures such as buildings, bridges, and dams.
They offer superior corros...
500D means the yield strength of TMT bars is 500 MPa.
500D is a grade of TMT bars used in construction.
The 'D' stands for ductility, which is the ability of the material to deform without breaking.
The yield strength of 500D TMT bars is 500 MPa.
These bars are commonly used in high-rise buildings, bridges, and other structures that require high strength and durability.
The required steel at the percentage concrete depends on the design and specifications of the structure.
The amount of steel reinforcement needed in concrete is determined by the design and specifications of the structure.
Factors such as the size and shape of the structure, the loads it will bear, and the desired strength and durability of the concrete will all affect the required steel percentage.
The steel percentage c...
Stress is the force applied per unit area, while strain is the deformation caused by stress.
Stress is a measure of the internal forces within a material, while strain is the measure of the deformation of the material.
Stress is expressed in units of force per unit area, while strain is expressed as a ratio of the change in length or shape to the original length or shape.
Stress and strain are related by the material's el...
The stress failure at brick wall can be due to compressive or tensile stress.
Compressive stress failure occurs when the brick wall is unable to withstand the weight or load placed on it.
Tensile stress failure occurs when the brick wall is unable to withstand the forces that pull it apart.
Cracking, bulging, or collapse of the wall can be signs of stress failure.
Reinforcing the wall with steel bars or using thicker brick
White marble is a metamorphic rock composed of recrystallized carbonate minerals, mainly calcite or dolomite.
It is commonly used in construction and sculpture.
It is formed from limestone or dolomite that has undergone heat and pressure.
It is often found in quarries in countries such as Italy, Greece, and India.
Standard coarse sand size ranges from 2.0mm to 4.75mm.

The number of cubes required for 250 cubic meters of concrete depends on the size of the cubes.
The size of the cubes needs to be specified to determine the number required.
The volume of each cube needs to be calculated.
Divide the total volume of concrete (250 cubic meters) by the volume of each cube to get the number of cubes required.
For example, if the cubes are 1 cubic meter in size, then 250 cubes would be needed.
