AbstractThe mechanisms responsible for high strength in cement paste systems are assessed in an attempt to define features common to selected new technologies, e.g., hot-pressed, impregnated, and macrodefect-free pastes. Important factors influencing strength of porous systems include porosity, pore geometry, C-S-H composition, composite behaviour and fracture criteria. The effects of low water-cement ratio, dense inclusions, stress modification in critical areas and their role in optimizing and controlling production of high- strength cement paste are discussed.
