Performance of geopolymer self compacting concrete using spent garnet as sand replacement

Robust engineering properties of spent garnet offer a recycling alternative to create efficient construction materials. Recycling of spent garnet provides a costeffective and environmentally responsible solution rather than dumping it as industrial waste. In this context, the present work evaluated...

Civil engineering (General) Robust engineering properties of spent garnet offer a recycling alternative to create efficient construction materials. Recycling of spent garnet provides a costeffective and environmentally responsible solution rather than dumping it as industrial waste. In this context, the present work evaluated the capacity of spent garnet as sand replacement to achieve self-compacting geopolymer concrete.

Experimental results revealed an enhancement in the workability of the proposed self-compacting geopolymer concrete specimens due to the increase in spent garnet contents.
