• The test helps in ensuring that the concrete mix has the desired properties for construction.

Cement is made by heating limestone with clay in a kiln, then grinding the mixture into a fine powder.

• Limestone and clay are crushed and mixed in proper proportions

• The mixture is then heated in a kiln at high temperatures

• After heating, the material is cooled and ground into a fine powder

Tests of cement are used to ensure its quality and strength for construction purposes.

• Setting time test: Determines how long it takes for the cement to set.

• Compressive strength test: Measures the maximum load the cement can bear before failure.

• Soundness test: Checks for the presence of uncombined lime in the cement.
