WebbOn the other hand, group П, the rubberized concretes, was made of concrete with 20% SF (HSC) with the inclusion of rubber waste particles of different ratios and sizes (3%, 5% fine rubber and 3% coarse rubber). Crushed dolomite was used as coarse aggregate instead of gravel in rubberized concretes. WebbAbstractTheoretically, there are two approaches to reducing the vibration induced by railway transit in cities: lowering structural stiffness, often used in subway design to isolate vibration, and absorbing the vibration by improving the damping ability ...

Development of self-consolidating rubberized concrete …

WebbIn the present work, the compressive behavior of rubberized concretes confined by steel tubes was investigated where the replacement percentages of fine aggregates with rubber were 0, 7.5, and 15%. Webb28 mars 2014 · One significant benefit is the property that rubber reduces mass density [ 15, 30] and increases deformability and ductility, so it is useful in elements that do not … so if i had to choose someone lyrics
