OHT stands for Overhead Tank. It is a water storage tank placed at a height to provide water pressure for distribution.
OHT is typically placed on the roof of a building or on a tower to ensure gravity-fed water supply.
The water is pumped into the OHT from a water source like a borewell or municipal supply.
The height of the OHT determines the water pressure available for distribution.
Pipes are connected from the OHT to ...
FHTC stands for First Horizontal Tangent Point, a key element in highway design.
FHTC marks the beginning of a horizontal curve on a highway.
It is typically located at the point where the road transitions from a straight section to a curved section.
Proper placement of FHTC is crucial for ensuring safe and efficient traffic flow.
Design considerations at FHTC include curve radius, superelevation, and sight distance.

Piling is a construction procedure used to strengthen the foundation of a building. It involves various methods and the time taken depends on several factors.
Piling is done using methods like driven piles, bored piles, and auger cast piles.
Driven piles involve hammering precast concrete or steel piles into the ground.
Bored piles are created by drilling a hole into the ground and filling it with concrete.
Auger cast pile...

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.
Standard coarse sand is commonly used in construction and civil engineering projects.
It is typically graded between 2.0mm to 4.75mm in size.
This type of sand is often used as a base material for concrete and asphalt.
It can also be used for drainage systems and as a bedding material for pipes.
The size and shape of the sand particles can affect the strength and durabi

The size of a slump cone is a tool used in concrete testing to measure the consistency of fresh concrete.
The size of a slump cone is typically 12 inches in height.
The base diameter of a slump cone is usually 8 inches.
The top diameter of a slump cone is typically 4 inches.
The size of a slump cone may vary depending on specific testing requirements or standards.
The dimensions of a slump cone are important for accurate me...
To estimate aggregate quantity for a 200sqmt slab, calculate the volume of concrete required and then determine the aggregate quantity based on the mix ratio.
Calculate the volume of concrete required for the slab
Determine the mix ratio of concrete (e.g., 1:2:4)
Calculate the volume of aggregates needed based on the mix ratio
Consider the bulk density of aggregates to convert volume to weight

Before casting, civil engineers need to check the quality of various elements.
Quality of concrete mix
Quality of reinforcement bars
Quality of formwork
Quality of water used in the mix
Quality of curing process
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.
Post concrete quality inspection involves evaluating the quality of concrete after it has been placed and hardened.
Inspect the concrete for any visible defects such as cracks, honeycombing, or segregation.
Check the concrete strength by conducting compressive strength tests on samples taken from the structure.
Assess the concrete's durability by examining its resistance to factors like freeze-thaw cycles or chemical expo...
The grade of concrete refers to its strength and durability.
Concrete is classified into different grades based on its compressive strength.
The grade of concrete is denoted by a number followed by the letter 'M' (e.g., M20, M25).
The number represents the compressive strength of concrete in megapascals (MPa) after 28 days of curing.
Higher grade concrete has higher strength and is used for heavy-duty structures like bridg...
