Alkali activated natural pozzolans for geopolymer cement

2021
This thesis deals with the use of six natural pozzolans from Germany and Italy for geopolymer production. As the first part, a detailed study was conducted on the effect of silica modulus of sodium silicate solution and mineralogical composition of natural pozzolans on the extend of geopolymer reaction, reaction kinetics, mechanical properties, and ...
