Ultra-high-performance concrete (UHPC) surpasses normal strength concrete in
engineering properties such as durability under extreme conditions, strength, and ductility …

Fire presents a significant danger to the survival of the building and inhabitants, adverse
effects at the structural level. In view of this, several researchers have measured the fire …

Concrete in service is unpredictably exposed to fire attack, while the properties of recycled
concrete aggregate (RCA) and recycled concrete powder (RCP) from demolishing fire …

This study investigates the effects of rehydration conditions (different hydration durations at
20° C/60% relative humidity (RH) and in water) on the mechanical and atomic structural …

With the increase of aggregate quarrying to meet the growing need for concrete construction
comes a risk associated with new aggregate sources, which may not have uniform …

In this work, the instant mechanical recovery and the thermal resistance of nanosilica (NS)-
incorporated cement composites were investigated. The composites were exposed to …

Fires are rare events, but in the case of their occurrence, they can have a significant effect on
the structure. Concrete is a durable noncombustible material but can be damaged by fire …

The feasibility of estimation of mechanical properties of limestone concrete after exposure to
high temperatures, using nondestructive methods, was investigated. Experimental study was …

High temperatures impose a negative effect on the mechanical properties of concrete. An
experimental setup designed by the theory of nonlinear resonance vibration, the method of …
