Abstract(s)
The problem of improving the quality of concrete is now becoming particularly relevant in
connection with the need to radically improve quality while reducing the material, labor and
energy intensity of reinforced concrete structures.
The solution of the set tasks for housing and other types of construction requires the
creation and wide application of new materials and technologies. In the construction industry,
one of the promising structural building materials is dispersed-reinforced concrete - fiberreinforced
concrete.
Varieties of fiber used in the production of fiber-reinforced concrete, allowed this type of
building material to find a fairly wide application in the modern construction industry.
Modern types of fiber do not allow performing bulk reinforcement of concrete and
reinforces only the concrete mixture without taking into account the filler of concrete, reducing
the efficiency of dispersed reinforcement.
Objective:
- Development of the design of fiber for disperses reinforcement of concrete;
- making samples of concrete without fiber, as well as samples using fiber with flattened
ends and fiber in the form of a segment of circular cylindrical shape;
- Laboratory testing of samples for obtains the characteristics of compressive strength.
The results of studies of samples of fiber concrete with dispersed reinforcement by metal
fiber are given. Conducted a comparative analysis of the compressive strength of samples from
concrete without fiber, as well as samples using fiber with flattened ends and fiber in the form of
a segment of round-cylindrical shape. To determine the strength characteristics, samples of
concrete and fiberconcrete cubes were made and tested in laboratory conditions.
