Development of Cement and Rice Husk Ash Blended Interlocking Paver Blocks

One major advantage of using concrete paving blocks is that they can be re-assembled easily using many construction patterns. Cement is a binding material, that sets and hardened independently and binds all the materials used in the construction of paver block. Paver blocks with wider range of colour combinations are produced with different type of oxide components. In view of the material scarcity, cost escalation due to the coloring pigments and the losing of colour due to wear and tear, the present research work developed product using the agro industry waste for naturally coloring the complete block, which may not fade in long run. The developed cement and rice husk ash blended paver blocks showcased a better strength characteristic, pleasant natural colour and reduce cost of product by reducing the use of cement in the concrete paver block by partial replacement with rice husk ash.

Wider range of application for pathways, vehicle parking sites, walkway in park, cycle ways and for motor ways. The developed paver blocks are suitable for both light weight to heavy weight vehicle usage. Self-interlocking system which is Suitable for laying above the percolation concrete pathways

• Uses natural black colour (Rice husk ash) instead of pigments
• Replaces partially the cement content
• Strength can be easily altered for wider application
• High wear and tear resistance proved
• Low cost (Rs. 23 per block for 30Mpa strength)
• High skid resistance texture vii Satisfied Indian Standard IS 15658-2006
