Thyrocare Technologies Interview Questions and Answers
Q1. What is the Physical & Chemical test of Steel Reinforcement?
Physical & Chemical tests of Steel Reinforcement include tensile strength, elongation, chemical composition, and corrosion resistance.
Tensile strength test measures the maximum stress a material can withstand before breaking
Elongation test measures the ability of the material to stretch before breaking
Chemical composition test determines the percentage of elements present in the steel reinforcement
Corrosion resistance test measures the ability of the material to resist rust a...read more
Q2. What is passing criteria of concrete cubes?
The passing criteria of concrete cubes is based on the compressive strength achieved by the cubes after a certain period of time.
The cubes are usually tested after 7 and 28 days of curing
The passing criteria varies depending on the grade of concrete used
For example, for M20 grade concrete, the passing criteria is 20 N/mm² after 28 days of curing
The cubes are tested using a compression testing machine
Q3. What are Aggregate test and results criteria?
Aggregate test is a method to determine the strength of coarse aggregates. Results criteria depend on the type of aggregate.
Aggregate tests include crushing value test, impact value test, and abrasion value test.
The results criteria for each test vary depending on the type of aggregate being tested.
For example, the crushing value test result criteria for basalt aggregate is 25%, while for limestone aggregate it is 30%.
The impact value test result criteria for basalt aggregate...read more
Q4. what are Pre & post pour checks for concrete?
Pre & post pour checks are essential to ensure the quality of concrete.
Pre-pour checks include inspection of formwork, reinforcement, and concrete mix design.
Post-pour checks include slump test, air content test, and temperature monitoring.
Other checks include curing, finishing, and testing for compressive strength.
These checks help ensure that the concrete is of the desired quality and meets the project specifications.
Q5. What is concrete cover & it's requirement?
Concrete cover is the thickness of concrete between the surface of embedded reinforcement and the outer surface of the concrete.
It is required to protect the reinforcement from corrosion and fire damage.
The thickness of the concrete cover depends on the type of structure and the environmental conditions.
The minimum concrete cover is specified in the design codes and standards.
For example, in reinforced concrete columns, the minimum concrete cover is 40mm.
In marine structures,...read more
Q6. What are Cement & concrete test?
Cement and concrete tests are used to ensure the quality and strength of the materials used in construction.
Tests for cement include fineness, setting time, compressive strength, and soundness.
Tests for concrete include slump, compressive strength, air content, and density.
These tests are important to ensure that the materials meet the required standards and specifications for construction projects.
Results from these tests can also be used to troubleshoot any issues that may ...read more
Q7. What is NCR & it's closing process?
NCR stands for Non-Conformance Report. It is a document used to record and track quality issues in a product or process.
NCR is used to document any deviation from the required specifications or standards.
It includes details such as the nature of the non-conformance, its location, and the corrective action taken.
The closing process involves verifying that the corrective action has been effective and the non-conformance has been resolved.
NCRs are important for identifying and a...read more
Q8. What is your experience with cement plant execution?
I have 5 years of experience in cement plant execution, including overseeing construction, quality control, and project management.
Managed construction projects from start to finish
Implemented quality control measures to ensure compliance with industry standards
Coordinated with various teams to ensure project deadlines were met
Utilized project management tools to track progress and identify areas for improvement
Q9. Quality in civil
Quality in civil engineering refers to ensuring that construction projects meet specified standards and requirements.
Quality in civil engineering involves ensuring that materials used meet specifications and standards.
It also includes ensuring that construction processes adhere to industry regulations and codes.
Quality control measures such as inspections and testing are used to verify compliance with quality standards.
Examples of quality issues in civil engineering include s...read more
