Concrete materials are subjected to a complex coupled environment of temperature,
humidity, and salt ions when in a coastal area during the summer. Geopolymer concrete …

The structural systems' critical point of flat slabs happens on the connection slab-column
through the shearing stressing concentrations, which may lead to the punching …

During a fire, ordinary Portland cement (OPC) systems lose their mechanical properties. For
this reason, it is important to find a way to protect it. This study suggested alternative uses of …

Fire damage poses a significant risk to reinforced concrete structures throughout their
lifespan. Fire exposure influences the stress-strain properties and durability of concrete …

The deterioration of concrete is greatly dependent on the cracks and microcracks
development owing to loading or environmental influences. An effective step to avoid the …

Neste estudo, investigou-se o efeito da incorporação de fibras de polipropileno (FP) no
concreto de alta resistência (CAR) em temperaturas elevadas, analisando possíveis …

The shotcrete structure commonly serves as a support system in a variable high-temperature
(VHT) environment of the high geothermal tunnels. However, the influence of the VHT …

The goal of this project is to evaluate how Nano Silica (NS) affects the qualities of high-
strength concrete (HSC) in its fresh state, hardened state, and durability. Five different …

The exposure of buildings built in reinforced concrete to fire situations can compromise their
structural performance due to significant changes in the mechanical resistance and stiffness …
