The durability of concrete has attracted significant attention over the past several decades
and is still a research hotspot until now. This paper reviews and discusses recent research …

The bonding behavior between ultra-high performance concrete (UHPC) and normal
concrete (NC) is crucial for enhancing the durability and performance of reparation and …

The existed studies about the freezing-thawing degradation of concrete mainly focused on
non-damaged concrete. This may overestimate the service life of concrete structures. In this …

In cold regions, rocks undergo freeze-thaw (FT) cycles, leading to damage caused by the
evolution of pores. This phenomenon significantly influences the rock mass stability. A …

A series of laboratory experiments were conducted to investigate the effect of freeze–thaw
(FT) cycles on mechanical properties and chloride permeability of concrete with the strength …

The peridynamic model introduced in this paper is capable of simulating the entire process
of concrete freeze-thaw failure. The model considers the heterogeneity of concrete and a …

In winter construction, early age concrete is easily threatened by frost damage. In order to
explore whether early concrete freeze occurred and its freezing degree, the deformation of …

The evolution and spatial distribution of internal random pore structure are key factors in
damage mechanism and macro-mechanical properties of concrete material under freeze …

This study investigates the freezing behaviors of two cement pastes saturated with water and
salt (NaCl) solutions of different concentrations. Special experimental set-up was designed …

The use of air-entraining agents (AEA) is one of the powerful means to reduce frost damage
of concrete. In this study, the effect of AEA on frost deformation, coefficient of thermal …
