compressive strength of blocks using sand and quarry dust aggregate

en/quarry dust for geopolymers.md at main · sbmboy/en · GitHub

Geopolymer compressed mortar blocks with both quarry dust and pond ash as fine aggregate developed higher strength than when natural sand was used as fine aggregate (Fig.7).Quarry dust is better placed compared to pond ash.This encourages the efforts of replacing sand with both pond ash and quarry dust.
