The influence of cement particle size distribution (PSD)on autogenous strains and stresses in cement pastes of identical water-to-cement ratio is examined for cement powders of four different finenesses. Experimental measurements include chemical shrinkage to quantify degree of hydration, internal relative humidity development, autogenous shrinkage, and eigenstress development using a novel embedded spherical stress sensor. Because the latter three measurements are conducted under sealed conditions, while chemical shrinkage measurements are made under
