Fibre-reinforced concrete (FRC) allows reduction in, or substitution of, steel-bars to reinforce concrete and led to the commonly named structural FRC, with steel fibres being the most widespread. Macro-polymer fibres are an alternative to steel fibr

This paper extends the previous work of the authors and deals with the study of fracture of sandwich panels of plasterboard and rock wool under in-plane bending and tensile loading. It presents the results of the experimental campaign focused on the

The compressive strength, flexural strength, porosity and electrical resistivity properties of cement mortars with nano-Fe2O3 and nano-SiO2 are studied. Amorphous silica is the main component of pozzolanic materials due to its reaction with calcium h

This paper presents the study of plasterboard and rockwool sandwich panels cracking under flexural loading. These panels are usually used to perform interior partition walls and they frequently show cracking pathology due to excessive deflexion of th

Stress relaxation losses on active reinforcement have significant impact on prestressed concrete structures. This is why relaxation tests are carried out on prestressing steel wires and strands after being manufactured. Then, these materials are coil

This paper presents a numerical procedure to simulate the cracking process of the brickwork masonry under tensile/shear loading. The model is an extension of the cohesive model prepared by the authors for concrete, and takes into account the anisotro

The use of self-compacting concrete (SCC) has been on the rise in recent years. Research on this type of concrete has focused primarily on determining optimal dosage, while durability, particularly for medium strength SCC, has received much less atte

Mechanical and physical properties of the masonry have a considerable bearing on the structural behaviour. Ancient buildings, like Leon’s cathedral, show uncertainty about real condition of the material and even structural compounds. These uncertai

This article discusses the results of research conducted on the failure behaviour of brick masonry under tensile and shear stress. The study was designed to develop test models and generate experimental results able to provide greater insight into te

This work relates the curing conditions of concrete with the damage caused by rapid freeze-thaw cycles (ASTM C 666). The “potential” durability of concrete after testing is also studied. In countries with a continental climate, the curing of conc
