This paper presents results from an experimental investigation that evaluated the mechanical activation of portland cement using vibro-milling. In this investigation, the duration of the vibro-milling was systematically varied and its influence was evaluated using mortar samples. In addition, the amount of activated cement used in the mortar samples was...
This paper studies the agglomeration of cellulose nanocrystals (CNCs) and uses ultrasonication to disperse CNCs in cement pastes in an attempt to improve strength. Rheological measurements show that when the concentration of CNCs exceeds 1.35% by volume in deionized water, agglomerates start to develop. This experimental finding is comparable to...
