Description
  • Abstract: Material properties provide the basic inputs for mathematic modeling of material. Creep of cement paste is possible to be assigned to the basic properties. In the paper, there are presented results of experimental testing of creep of cement paste. Cement pastes were prepared from Portland cement CEM II. Selected w/c ratios 0.3; 0.4 and 0.5 were used for preparation. Tested specimens were heated by temperature of 300 °C before start of testing. The shape of specimens was a cylinder with diameter 10 mm and length 70 mm, and specimens were tested in special lever mechanism designed for creep test of small-grained materials. The results of testing are divided into the creep of specimens and shrinkage of specimens. In the first chapter, there is described the preparation of specimens. The second one includes the results of material tests, i.e., compression strength and modulus of elasticity. Results of creep tests, especially graphs from creep tests are described in the next chapter, and finally, results are summarized. In the results of creep tests, there are presented graphs of water dried and saturated specimens and results are discussed.
