Clay - Fly Ash Burnt Bricks - An Experimental Study

Jayant L. Patil ,Dr. Arun Kumar Dwivedi

The fly ash for the purpose of experimentation was collected from the Thermal Power Station (Eklahre) in Nashik, Maharashtra. The mixtures of clay available at the site and the fly ash with different percentages by weight are prepared. These mixtures are used to make the bricks of clay and fly ash with different proportions. The bricks are marked with specific numbers in their frog to identify them at the time of testing. These bricks are air dried in open atmosphere for 4 - 5 days as per usual practice. The firing of the bricks is done in a traditional way as is done in and around Dhule town. These bricks are fired for fourteen days. At the end of the 14 days, the kiln is allowed to cool as per usual practice. The bricks are taken out from the kiln and stacked in the testing lab of the institute where the sample bricks are tested for water absorption, density and compressive strength as per BIS procedures.
