摘要: Abstract The adhesion mechanisms between C S H and fillers are of great significance when employed as a cement replacement. affinity filler's surface towards ions in the pore solution paste is reported this work from view point governing mechanisms. discussion on various interactions justified by results zeta-potential measurements, further supported microscopic observations hydration products surfaces. bond strength filler hydrates also evaluated. H/filler appears due to calcium ions. In case calcite, predominantly determined acid-base which lead formation strong (most likely ionic-covalent bond). silica, found be governed an attractive ion-ion correlation force.
