Effect of phase transformations, chemical doping, and matrix constraint on the microstructural development of dicalcium-silicate
Abstract
dc:descriptionThe factors controlling the monoclinic (β) to orthorhombic (γ) transformation of dicalcium silicate (Ca$\sb2$SiO$\sb4$) at about 490$\sp\circ$C have been studied. This transformation is of interest in portland cement technology because the low temperature γ phase is unreactive with water, while the high temperature β phase is. The transformation, which is accompanied by a 12% volume increase and a 4.6$\sp\circ$ unit cell shape change, is analogous to the tetragonal-to-monoclinic transformation of ZrO$\sb2$. Thus Ca$\sb2$SiO$\sb4$ is a potential transformation toughener alternative to ZrO$\sb2$.
