Fine-grained carbonate concretes (FGCC) have presently proved to be quite applicable with good parameters on crack- and freeze-thaw performance as criteria of durability and reliability of building materials and structures. The purpose to enhance deformative characteristics of FGCC is actually a search for economically and ecologically proven ways for it. The paper presents the results of strain’s study of fine-grained carbonate concretes with limestone fines and superplastisizer. Strains are classified as instant, short-term and long-term (creep). A method of planning experiment is used in the study. To measure strains, electric gauges and clock-type indicators were used. It was shown that a complex additive enhances both durability and performance of fine-grained carbonate concretes due to modification of their structure formation and hardening.
