THE INFLUENCE OF FINELY GROUND MINERAL ADMIXTURE (FGMA) ON EFFLORESCENCE

Efflorescence phenomenon on concrete is not new and found in the form of white deposits on surfaces of concrete. Incorporation of Finely Ground Mineral Admixture (FGMA) in concrete to prevent occurrence of efflorescence is based on reduction of portlandite, densified microstructure and thus enhanced...
