The effect of barite rate on some physical and mechanical properties of concrete

Medida de las principales propiedades en el estado fresco, y de la resistencia a la segregación, en un hormigón autocompactante de alta densidad fabricado con barita

“…Table 3 shows the chemical composition. Since the sulfate content is under 90%, according to the literature the highest densities that can be attained are on the order of 3400 kg/m 3 (4,5). This was later corroborated.…”

“…La Tabla 3 muestra su composición química. Puesto que el contenido de sulfato es menor del 90%, la literatura indica que es difícil obtener hormigones con densidades superiores a los 3.400 kg/m 3 (4,5). Este hecho se corroboró posteriormente.…”

Effects of Barite Sand Addition on Glass Fiber Reinforced Concrete Mechanical Behavior

“…The addition of this mineral in small quantities can enhance the concrete behavior against the radiation waves compared to the conventional concrete mixes [8,9]. Some researches results showed that addition of barite mineral can not enhance the mechanical properties of the ordinary concrete [10,11].…”

Influence of High Temperature on Concrete Produced from Portland Cement with Boron Additives

“…Boron compounds have been used as additives in the production of cement and concrete, for enhancing such engineering properties as fire resistance and radiation shielding [2][3][4]. The improvements and additional features (neutron shielding, fire resistance, antibacterial properties, etc.)…”
