As the construction industry is facing the challenge of meeting the ever-increasing demand for environmentally friendly and durable concrete, the role of viscosity-modifying admixtures (VMAs) has become increasingly essential to improve the rheologic

Fresh cement pastes behave as viscoelastic materials below the flow onset. The measurements of viscoelastic properties of fresh cement paste provide valuable insight into the dispersion of solid particles as well as the hydration kinetics at early ag

Is crushed concrete carbonation significant enough to be considered as a carbon mitigation strategy?
Publikováno v:
Environmental Research Letters, Vol 17, Iss 10, p 104049 (2022)
When addressing concrete carbonation as a carbon mitigation option, studies leave out the effect that a temporal difference between the CO _2 emissions and uptake happening throughout concrete’s life cycle have on climate change. In this study, the

Measuring Rheological Properties of Cement Pastes: Most common Techniques, Procedures and Challenges
Publikováno v:
RILEM Technical Letters, Vol 2, Pp 129-135 (2017)
The science of rheology is increasingly used to describe the properties of fresh cement paste. Compared to standard workability tests, rheological properties allow for more fundamental investigation, more precise phenomenological description of flow

This paper presents an experimental investigation of the hygrothermal and mechanical properties of innovative mortar mixtures reinforced with natural fibers. Fibers extracted from palm stems (PS) and hemp (HF) were evaluated at different percentages.

Current climatic changes are occurring due to various human and industrial activities. In particular, the effects of urbanisation and growing threat of global warming have likely caused increasing precipitation in many geographic regions. For many ye

A constitutive model to describe the triaxial load-response spectrum of plain concrete in both tension and shear was developed. The inelastic phenomena are described using the plastic flow with direction determined by the gradient of the plastic pote
