- •
Rice husk ash and spent diatomaceous earth were used as a source of silica.
- •
Rice husk ash and spent diatomaceous earth delay the setting time of the geopolymer.
- •
Similar compressive strength were achieved in the geopolymer by using RHA and SDE.
- •
To use rice husk ash and spent diatomaceous earth reduce the geopolymer bulk density.
