Densely packed cementitious materials

Densely packed cementitious materials are commonly also called also DSP materials, which is an acronym for Densified Systems containing homogeneously arranged ultrafine Particles. The alternative term reactive powder concrete is also used. In principle these are cementitious materials formed by the Itydration of densely packed particles of an inoiganic binder in combination with ultrafine particles of a second, less reactive or non-reactive filler. Some additional particulate materials may also be present.
