Many ordinary portland cement (OPC) OPC-pulverized fuel ash (pfa) blended pastes of various ages have been examined using transmission electron microscopy, energy dispersive x-ray analysis, and scanning electron microscopy. In the pfa-blended cements, some of the pfa particles reacted to give a radially fibrillar gel, and others showed areas of well-crystallized hydrogarnet within the clearly defined outer boundary of the particle.
