Chloride diffusion in concrete is a main aspect of reinforced concrete durability. It defines the time required for reinforcement corrosion in marine structures. Concrete porosity is one of the main concerns involved in ...

This paper deals with the effect of silica fume and styrene-butadiene latex (SBR) on the microstructure of the interfacial transition zone (ITZ) between Portland cement paste and aggregates (basalt). Scanning electron ...

The aim of this study was to evaluate the influence of sugarcane industrial ash (SCIA) on mechanical properties of interfacial transition zone (ITZ) between aggregates and cementitious matrix by nanoindentation technical ...

The present study shows the application of the nanoindentation technique to evaluate the properties of the cellulose fiber-cement matrix interfacial zone in composites prepared with an auger extruder. The degree of strength ...

The use of recycled concrete aggregates in new concrete is an alternative that can provide economical and environmental benefits. However, the influence of the inert particles on the mechanical behavior of concrete needs ...

Deformations in normal strength concrete (NSC) and high performance concrete (HPC) were examined using image analysis to better understand the distribution of strain in these materials as related to their composition and ...

The objective of this chapter is to discuss some aspects that affect the interfacial transition zone between lignocellulosic fibers and cement matrix, such as raw materials, processing, and curing methods. A major advantage ...

Image analysis and strain mapping were used to examine the nature of elastic, creep and shrinkage strains in high performance lightweight concrete (HPLC). The strain maps showed non-uniform deformations related to ...

The mesostructure of concrete plays a very important role in the process of initiation and propagation of cracks. Microcracks tend to start in the Interfacial Transition Zone (ITZ) and propagate toward the mortar matrix ...
