Geotechnical and thermal analysis and complex impedance spectroscopy characterization of pure Moroccan bentonite material for civil engineering applications
Mohamed Essaleh, Rachid Bouferra, Imad Kadiri, Soufiane Belhouideg, Mohammed Mansori, Abdeltif Bouchehma, Mohamed Oubani, Mohamed Benjelloun Combined modulus and impedance spectra are employed in the present work to explore electrical inhomogeneity and carriers’ behaviors in a pure bentonite Moroccan clay based on equivalent circuit. It has been clearly observed that the electrical properties change due […]
Implementation of marble waste as aggregate material rigid pavement
Candra Aditya, Dafid Irawan, Silviana Silviana The rigid pavement is used for the pavement with soft ground conditions (subgrade). On the other hand, in recent years, marble waste for civil construction has been widely used to substitute conventional materials such as fine and coarse aggregate in concrete. This study aims to optimize marble sand waste […]
INFLUENCE OF FINE ADDITIVES AND SURFACTANTS ON THE STRENGTH AND PERMEABILITY DEGREE OF CONCRETE
Oksana Shkromada, Andriy Paliy, Oksana Yurchenko, Nadiia Khobot, Alina Pikhtirova, Ivan Vysochin, Ganna Fedorenko, Anatoliy Paliy The results of studies to determine the effect of titanium dioxide nanoparticles (nanoTiO2), finely dispersed anatase crystalline titanium dioxide (anatazTiO2) and surface-active substances (surfactants) on the compressive strength, degree of permeability and thermal stability of concrete samples are presented. […]
DETERMINATION OF MECHANICAL PROPERTIES OF REPAIR MORTARS USING IN SITU METHODS UNDER DIFFERENT CURINGS
Ali Saberi Varzaneh, Mahmoud Naderi Considering the differences between environmental conditions of concrete structures and laboratory conditions, it is important to determine the parameters of the materials at the site of the structure. One of these materials is cement-based repair mortars due to the damage of concrete structures that may arise due to chemical or […]
