Abstract The dynamic development of nanotechnology research has contributed to the fact that various types nanoparticles are increasingly used on a large scale both for medical and biological purposes, but above all in many industrial fields. Such wide application is often connected with need estimate their characteristic parameters, such as size, size distribution or concentration. Existing in...

The paper presents the effect of different synthesis parameters, such as (a) fly ash to alkaline solution ratio, (b) concentration of NaOH solution, (c) concentration of sodium silicate solution, (d) geopolymer solids to water ratio and (e) sodium silicate to sodium hydroxide solution ratio, on the compressive strength of geopolymer concrete synthesized from fly ash of Indian origin. It is obse...
