Ultra-high-performance concrete (UHPC) shows high tensile strength, compressive strength,
and durability compared to normal strength concrete (NSC). However, high compactness …

To retrofit a fire damaged structural element, it is important to understand the extent of
thermal exposure of such structural element. It is presumed that the extent of damage of fire …

Superabsorbent polymers (SAP) are a new, promising class of chemical admixtures which
offer new possibilities in respect of influencing the properties of cement-based materials in …

Ultra-high performance concrete (UHPC) is a novel concrete class characterized by a
compressive strength of more than 150 MPa. One of the most significant drawbacks of …

Progress in microstructural characterization methods is summarized. Special attention is
given to advanced probes, such as X-ray imaging and spectroscopy, 1 H NMR relaxometry …

This paper presents results from experimental studies on residual mechanical properties of
fiber-reinforced concrete specimens exposed to elevated temperatures. Seven series of …

Abstract Service life and durability of reinforced concrete structures have become crucial
issues in all industrialized countries because of their economic and ecological relevance …

Concrete tends to spall explosively under fire due to the combined effect of thermal stress
and pore pressure build-up. For an anti-spalling strategy in the concrete mix design, one can …

The decrease in concrete resistance and the expansion generated in reinforced concrete
structures by direct exposure to fire at 400° C maximum temperature serves as the basis for …

Fibers reinforcement which is an effective mean to improve the cracking resistance of high
performance concrete (HPC) is widely applied in practice. The early-age cracking resistance …
