Impact of Growth on Physical, Mechanical and Rheological Properties of High Strength Steel Fiber Reinforced Concrete

The paper presents the results of experimental study focused on physical, mechanical and rheological characteristics of high strength steel fiber reinforced concrete. The research program included short-term tests to determine strength properties as well as long-term test to obtain shrinkage and creep deformation. All tests were carried out on the different age specimens, so the time history of material properties was determined and analytic expressions of physical, mechanical and rheological properties dependence on concrete growth were developed.
