A Short Review on the Valorisation of Sugarcane Bagasse Ash in the Manufacture of StabilizedSintered Earth Blocks and Tiles

الملخص EN

Valorisation of solid wastes in the manufacture of soil based building materials is one of the several technically feasible and cost-effective solutions for waste management.

Sugarcane bagasse ash is one such solid waste generated in huge quantities in India, a leading sugar producer.

This paper aims at reviewing the valorisation of sugarcane bagasse ash in the manufacture of stabilized as well as sintered earth blocks.

Sugarcane bagasse ash is a silica rich material that can play the role of an effective pozzolan leading to enhanced pozzolanic reactions resulting in better performing building materials.

The reviewed literature reveals that it has been utilized in the manufacture of blocks as well as tiles in the form of an auxiliary additive as well as a primary stabilizer.

However, its utilization in stabilized blocks has been more common compared to sintered blocks due to higher energy consumption in the latter.

To summarize, sugarcane bagasse ash not only has improved performance in most of the cases but also has reduced the cost of the material, leading to the conclusion that its valorisation in manufacture of blocks and tiles is a genuine and highly productive solution for waste management as well as cost economy.
