Reinforced concrete structures are often damaged by corrosion, which affects the interaction between reinforcement bars and concrete. Earlier studies mostly applied artificial corrosion to test the bond between deformed bars and concrete. However, there is a lack of knowledge on the effects of natural corrosion on plain bars. In this paper, 20 beam...

Plastic deformation behaviour of graded crushed stone (GCS) base affects the service life of flexible pavement. This paper presents a simple prediction model to characterize the plastic deformation behaviour of GCS base. A relative deformation model was proposed based on the deformation model developed by Pérez. The plastic deformation test was con...

The paper deals with the production of lightweight gypsum composites by means of a vegetal protein foaming agent. Two manufacturing methods, which basically differ in the physical state of the foaming agent used, have been proposed and the relative experimental results have been compared and discussed. The gypsum foam samples have been characterize...

In this paper, magnesium oxychloride cement (MOC), which has a needle-like structure, is upgraded with super-hydrophobic surface using a facile method involving immersion in a FAS-ethanol solution. The influence of the molar ratios of the raw materials on the super-hydrophobic property was investigated. The phase compositions, microstructure, compr...

This paper presents results on corrosion characteristics of 66 rebars extracted from un- and pre-cracked plain concrete and fibre-reinforced concrete (FRC) beams suffering from corrosion for more than 3 years. The influences of fibre reinforcement, flexural cracks, corrosion-induced cracks and loading condition on the maximum local corrosion level ...

Different methods for the estimation of fiber reinforced polymer (FRP) contribution to shear strength in reinforced concrete (RC) beams were evaluated and compared through reliability analysis using FRP rupture and debonding failure functions. The carbon fibers properties were obtained through laboratory tests allowing to define the probability dis...

The incorporation of graphene oxide (GO) into ultra-high performance concrete (UHPC) can solve the problems of brittle fracture and low tensile strength of UHPC to some extent. By means of molecular dynamics simulation, this paper provided an insight into the interfacial bonding between GO and calcium silicate hydrate (C-S-H) gel, the dominant comp...

The master curve of a viscoelastic variable is of significance due to its capability of characterizing the linear viscoelastic (LVE) property in an extended time or frequency range. However, the master curves constructed using the traditional approach fail to strictly comply with the LVE theory, leading to inaccurate predictions in the extended ran...

In order to solve the problems of low strength and brittle failure of plain ice when used as building material, ice was reinforced with primary pulp fibers. The fiber reinforced ice (FRI) was researched with uniaxial compressive tests under 20 working cases to investigate the effects of temperature (− 20 °C, − 15 °C, − 10 °C, − 5 °C) and fiber cont...
