Abstract
The article presents an analytical review of native and foreign investigations of the free and restricted shrinkage features for concrete on dense and porous aggregates. Two different theories are considered, satisfactorily describe the shrinkage process and are not mutually exclusive. The issues related to the influence of aggregate components, cement, water-cement ratio and additives on shrinkage of claydite-concrete are highlighted. The proposals on accounting for shrinkage deformations in claydite-concrete and reinforced claydite-concrete are considered. The technique has been developed for specimens’ investigations in the form of prisms reinforced with longitudinal nonprestressed reinforcement using indicating gage for measuring shrinkage strains. The suggested technique is required to more accurately determine the process of accumulation of volumetric shrinkage strains and improve the mathematical model for calculating the relative shrinkage strains in claydite-concrete and reinforced claydite-concrete.
