The restrained ring test is becoming widely used as a standard test method to assess the potential for early-age cracking in concrete mixtures. Previous research focused on the …
A new image analysis procedure for quantifying microcracks from three-dimensional (3D) X- ray microCT images of concrete is presented. The method separates microcracks from air …

This paper describes the use of acoustic emission (AE) for monitoring early-age cracking in restrained fiber-reinforced mortars. A steel-testing frame was used to prevent the length …
In this study, the flexural strength and fatigue properties of interfacial transition zone (ITZ) were experimentally investigated at the micrometre length scale. The hardened cement …

This paper concerns the origin of eigenstresses in lightweight aggregate concrete (LWAC) caused by autogenous deformation and drying shrinkage. Autogenous deformation of …
The main assumption of eco-efficient High-Performance Concrete (HPC) design is the reduction of Portland cement clinker content without negatively affecting the composite's …
Concrete experiences volumetric changes as a result of material formation (cement hydration), thermal variations, or moisture losses. If these volume changes are prevented by …
