I applied via Approached by Company and was interviewed in Mar 2018. There was 1 interview round.
The reaction when water is added to cement is called hydration.
Hydration is a chemical reaction that occurs between water and cement.
During hydration, the water molecules react with the cement particles, forming chemical compounds.
This reaction is exothermic, releasing heat as the cement hardens and gains strength.
Hydration is a crucial process in the setting and curing of cement-based materials.
Examples of hydrated co...
The 3, 7, and 28 days strength of cement is determined through testing in accordance with our company's Test Report.
The strength of cement is an important factor in determining its quality and suitability for various applications.
The 3, 7, and 28 days strength refers to the compressive strength of cement after specific curing periods.
Testing is conducted to assess the cement's ability to withstand pressure and load.

Insoluble residue refers to the solid material that remains after a substance has been dissolved or extracted.
Insoluble residue is the solid residue left behind after a liquid has been evaporated or a solution has been filtered.
It is often used in analytical chemistry to determine the amount of impurities or contaminants in a substance.
For example, in the analysis of water samples, the insoluble residue can indicate th...

The specification of cement, sand, and aggregate refers to the ratio of these materials used in concrete mixtures.
The specification is usually expressed as a ratio of the materials used in the mixture.
For example, a common specification for concrete is 1:2:3, which means one part cement, two parts sand, and three parts aggregate.
The specification can vary depending on the intended use of the concrete, such as for found...

I applied via Recruitment Consultant and was interviewed in Sep 2021. There was 1 interview round.
Soundness of cement refers to its ability to resist volume changes after setting.
Soundness is important for durability and strength of concrete structures.
It is measured by the Le-Chatelier test or the Autoclave test.
If the cement expands or contracts excessively, it can cause cracking and weaken the structure.
Factors affecting soundness include the composition of raw materials, fineness of grinding, and curing conditi
Testing of cement involves various physical and chemical tests to ensure its quality and strength.
The compressive strength test is the most common test for cement.
Setting time test is done to determine the time taken by cement to set.
Soundness test is done to check the stability of cement against volume changes.
Fineness test is done to measure the particle size of cement.
Chemical analysis is done to check the chemical ...
