Chemical reaction and consolidation (physical phenomena of hardening) were also correlated. The chemical reaction rate was accompanied using isothermal calorimetry and the consolidation measured using oscillatory rheometry (quantifying the storage modulus \u2013 G\u2019 and relating with yield stress, s0). The results show that BR accelerates the cement hydration reaction, but in pastes with pure cement, consolidation was faster, showing a distinct effect on the fluid-solid transition.<\/p>","protected":false},"excerpt":{"rendered":"<p>Authors: Romano, Roberto Cesar de O.; Liberato, Caio, C.; Montini, Marcelo; Gallo, Jorge B.; Cincotto, Maria A.
