These matrices reached compressive strength values over 100 MPa, much stronger and denser than obtained by using Portland Cement binders. Size fractions were obtained by size separation techniques and the relationship between strength and particle size was investigated. The differences in compressive strength measured in the geopolymers made from fine fractions, the original fly ash and a coarse fraction of the same ash, were not significantly higher than the variation found for a reference geopolymer material. Therefore, a direct size-strength relationship could not be proven. Moreover, the chemistry and the pH of the fractions also varied, and this might as well has played a role in the strength development. </p></abstract><publication_date><month>04</month><day>30</day><year>2013</year></publication_date><pages><first_page>155</first_page><last_page>161</last_page></pages><publisher_item><identifier id_type="pii">593</identifier></publisher_item><doi_data><doi>10.30955/gnj.000593</doi><timestamp>1714130270</timestamp><resource>https://journal.gnest.org/publication/593</resource></doi_data></journal_article></journal></body></doi_batch> </div>
