The paper presents research of shrinkage of the cement paste. The tested specimens wereprepared eight years ago from Portland cement CEM II and water. The observation was focused onthe evolution of creep in long time and for very old material. The material properties like a compressionstrength and Modulus of elasticity were observed according with the creep.
The paper presents research in area of the measurement of cement paste creep. The propertiesof four month cement paste mixed with fly ash are presented. The creep and shrinkage are measuredinto the lever mechanism. The basic creep and creep of the saturated cement paste are calculatedfrom data of measurement. Finally, creep of four months old specimens is discussed.
