This study experimentally investigated the effects of surfactants and water-repelling agents on hydration process, relative humidity, mechanical properties Portland cement pastes. Based measurement results, degree hydration, saturation, capillary tension autogenous shrinkage, magnitude shrinkage were simulated using a numerical model. In model, elastic creep components calculated separately, co...

This paper investigates material properties of metakaolin/slag-based geopolymer mortar (GPM), relevant for composite action with conventional Portland cement-based concrete (PCC). GPM formulations different workability (soft and stiff-plastic consistencies) were developed characterized regard to their compressive tensile strength development over time, shrinkage behaviour during hardening under...

This study investigates the deformation of free and stress restrained alkali-activated slag concrete (AASC), respectively, under semi-adiabatic condition. The shows first thermal expansion, which is compensated soon by autogenous shrinkage. subsequent cooling down aggravates shrinkage development tensile stress, eventually results in early cracking concrete. show that condition severer for AASC...
