M stands for 'Mix' in M20.
M20 is a designation for a concrete mix with a compressive strength of 20 megapascals (MPa).
The 'M' in M20 represents the word 'Mix', indicating that it is a mix of cement, sand, and aggregate.
The number following 'M' in M20 denotes the compressive strength of the concrete mix.
Different grades of concrete have different compressive strength requirements, and the 'M' designation helps in identi
Curing is necessary for concrete to ensure proper hydration and strength development.
Curing prevents moisture loss from the concrete, allowing it to maintain its desired water-cement ratio.
It helps in reducing shrinkage and cracking by providing a controlled environment for the concrete to cure.
Curing promotes the formation of calcium silicate hydrate (CSH) gel, which contributes to the strength and durability of concr...
Water is added to concrete after casting to maintain moisture content and achieve early strength and resist creep formation.
Adding water to concrete after casting helps to prevent excessive moisture loss.
Maintaining moisture content in concrete is important for proper hydration of cement particles.
Watering concrete can also help in reducing shrinkage and cracking.
By providing moisture, the concrete gains strength faste...
The steps involved in concreting include site preparation, formwork, reinforcement, mixing, pouring, leveling, finishing, and curing.
Site preparation involves clearing the area and ensuring proper drainage.
Formwork is constructed to shape and support the concrete.
Reinforcement is placed to provide strength to the concrete structure.
Concrete ingredients are mixed in the correct proportions.
The mixed concrete is poured i...
The allowable height for free fall for concrete depends on several factors.
The allowable height for free fall for concrete is typically specified by the project specifications or industry standards.
The height is influenced by factors such as the type of concrete mix, slump value, and the presence of reinforcing steel.
For example, for normal weight concrete with a slump of 3 to 4 inches and no reinforcing steel, the all...
Segregation is the separation of coarse and fine particles in concrete mix, while bleeding is the upward movement of water in fresh concrete.
Segregation occurs when the coarse aggregates settle down due to gravity, resulting in a non-uniform distribution of particles in the mix.
Bleeding happens when excess water in the concrete mix rises to the surface, leaving behind a layer of water on top.
Segregation can lead to a d...
Bleeding and segregation are common issues in concrete construction.
Bleeding occurs when excess water in the concrete mixture rises to the surface, leaving behind a layer of water.
Segregation happens when the coarse aggregates separate from the rest of the concrete mixture.
Both bleeding and segregation can negatively impact the strength and durability of the concrete.
Proper mix design, adequate compaction, and appropri...

Hydro power test of DI pipes is a method to check the strength and integrity of ductile iron pipes under pressure.
Hydro power test involves filling the DI pipes with water and pressurizing them to a specified level.
The test is conducted to ensure that the pipes can withstand the pressure they will be subjected to in actual use.
Leaks or deformations during the test indicate weaknesses in the pipes.
The test helps in iden...
I applied via Walk-in and was interviewed before Jan 2023. There was 1 interview round.
Lap length is the overlap of reinforcement bars in concrete, while development length is the length of bar required to transfer stress to concrete.
Lap length is used to ensure continuity of reinforcement across a joint or splice in concrete elements.
Development length is required to develop the full strength of the reinforcement bar and transfer it to the surrounding concrete.
Lap length is typically specified in terms ...
The weight of a solid block with dimensions 400*400*200mm depends on the material it is made of.
The weight can be calculated by multiplying the volume of the block by the density of the material.
Different materials have different densities, so the weight will vary depending on the material.
To calculate the volume, multiply the length, width, and height of the block.
To find the weight, multiply the volume by the density...

Quality control is a process used to ensure that products or services meet specified requirements and standards.
Quality control involves inspecting, testing, and evaluating products or services to ensure they meet quality standards.
It also includes identifying defects or deviations from specifications and taking corrective actions.
Quality control helps to prevent defects, improve processes, and enhance customer satisfa...

The hydraulic gradient line is a line representing the total head of water at various points along a flow path in a hydraulic system.
It is a graphical representation of the total head of water in a hydraulic system.
It shows the energy level of water at different points along a flow path.
The slope of the hydraulic gradient line indicates the direction and rate of flow of water.
It is used in analyzing flow patterns and d...
Methods for managing floods include structural measures, non-structural measures, and preparedness planning.
Structural measures include building dams, levees, and flood walls to control water flow.
Non-structural measures involve land-use planning, zoning regulations, and wetland preservation to reduce flood risk.
Preparedness planning includes early warning systems, evacuation plans, and community education on flood saf...
Prestressed concrete is a type of concrete that has been compressed prior to being subjected to loads.
Prestressed concrete is created by introducing internal stresses in the concrete before it is subjected to external loads.
This compression helps to counteract the tensile stresses that the concrete will experience during use.
Prestressed concrete is commonly used in bridges, parking structures, and high-rise buildings.
E...
A flood wall is a structure designed to prevent flooding by holding back water.
Flood walls are typically made of concrete, steel, or other strong materials.
They are commonly used along rivers, coastlines, and other areas prone to flooding.
Flood walls can vary in height and design depending on the level of protection needed.
Examples of flood walls include the Thames Barrier in London and the flood walls along the Missis
The hydrotest pressure is 1.5 times the design pressure.
Hydrotest pressure is the pressure applied to a vessel or pipeline to check for leaks or defects.
It is usually done before commissioning the system.
For example, if the design pressure is 100 psi, the hydrotest pressure would be 150 psi.
The procedure for fit up inspection includes classification, cleaning, alignment, root gap, root face, bevel angle, and mismatch or overlap.
Classify the base metal
Clean the surface
Align the parts to be joined
Check the root gap and root face
Measure the bevel angle
Check for any mismatch or overlap
Ensure all specifications are met
