Abstract (en)
The interest of the professional public in the field of civil engineering for
usage of self-compacting concrete and potentials of implementation of
recycled aggregate in making of this type of concrete is on the rise,
primarily because of the dwindling reserves of natural raw materials, and
because of the increasing amounts of construction rubble and waste. The
experimental-theoretical analysis implemented in this dissertation was
used to monitor and analyze behaviour of reinforced concrete continuous
beams made of self-compacting concrete made from natural (river)
aggregate, as well of continuous beams in which the coarse natural
aggregate was replaced in varying proportions, with the quality
aggregate made of recycled concrete prefabricates. In addition to
defining the ultimate strength state, the ultimate serviceability state was
verified, while the stress-strain states of the beams and formation of
plastic joints was monitored. Comparative analysis of experimental
results was conducted, in which continuous beams with varying share of
steel reinforcement made of self-compacting concrete with natural
aggregate and the beams made of the self-compacting concrete with
quality recycled aggregate were compared. By using the finite element
method, continuous beams were modelled, and numerical non-linear
analysis was conducted. The continuous beams where coarse natural
aggregate was partially replaced by the recycled aggregate are
comparable, in structural terms, and competitive with the beams made of
self-compacting concrete made with natural aggregate, and they are also
justified in terms of environment protection.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
