چکیده
The article presents the results of research on modified steel fiber-reinforced concrete and shows expediency their use to increase effectiveness fortification protection structures against shock loads. It was established that according tests compressive strength (fсm = 79.4 MPa) tensile during bending (fс, lf 7.4 MPa), can be classified as high-strength (strength class C 50/60) rapid-hardening (fcm2/ fcm28 0.57) in accordance with DSTU EN 206:2018. Manufacturing factory conditions reinforced elements based increased resistance various types force effects shelling will allow obtain quick-assembling/quick-dismantling able provide for personnel units armed forces Ukraine.

Some Studies on Steel Fiber Reinforced Concrete
Fibres are generally used as resistance of cracking and strengthening of concrete. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural strength of concrete. According to various research papers, it has been found that steel fibres give the maximum strength in comparison to glass and polypropylene fibres. Hence, in this pr...
متن کاملA micromorphic model for steel fiber reinforced concrete.
A new formulation to model the mechanical behavior of high performance fiber reinforced cement composites with arbitrarily oriented short fibers is presented. The formulation can be considered as a two scale approach, in which the macroscopic model, at the structural level, takes into account the mesostructural phenomenon associated with the fiber-matrix interface bond/slip process. This phenom...
