This paper is a keynote presentation from the 13th International Congress on the Chemistry
of Cement. It discusses the underlying principles of hydration and recent evidence for the …

Concrete is the largest volume material used by man and is irreplaceable for innumerable
large infrastructure developments. From the point of view of natural resources, ecology and …

Water to cement (W/C) ratio has been deemed as one of the most important factors affecting
the properties of concrete. However, at constant W/C ratio, cement or cementitious paste …

This paper investigates the reinforcement efficiency of mortars produced with different types
of carbon nanotubes (CNTs) in terms of their mechanical strength, ultrasonic pulse velocity …

The latest research data indicates that geopolymer concrete reinforced with mono fibre has
a remarkable enhancement in its impact strength and fracture toughness, which is well …

The interfacial transition zone (ITZ), located near aggregates, is characterized by low cement
content and high porosity and is the weak link in cement-based materials. Considering the …

The effect of fly ash (10, 20 and 30%) and silica fume (5 and 10%) as a substitute for cement
in binary and ternary mixtures on the properties of fresh and hardened concrete are …

Identifying the properties of the region where the cement paste meets the aggregate surface
(interfacial transition zone, ITZ) is critical to understanding the strength and fracture behavior …

This paper presents an experimental study of the influence of different superplasticizer
dosage on compressive strength and micro-structure characteristics of interfacial transition …

The interfacial transition zone (ITZ), existing between the cement matrix and aggregates, is
commonly viewed as a weak link for its highly porous microstructure. Enormous research …
