Summary:Authors make blended cement with fly ash, blast-furnace slag, and SiO sub 2fume additives, and examine hydration degree, combined water content, and Ca(OH) sub 2 content of pastes cured for < 120 d. All these blending agents enhance hydration considerably. The apparent overall reactivity of these blending agents has two components: 1) particle size effect (as shown by blending with a nonhydraulic material, rutile) and 2) inherent hydraulicity of the material.
