In the scope of his study, the physical and mechanical properties of the rubberized … Webb20 juni 2007 · The rubberized concretes contained both types of rubbers (crumb and chip) with three designated rubber contents of 5, 15, and 25 by total aggregate volume. The rubber content was divided equally between the crumb and the chip.
Webb1 dec. 2004 · The physical and mechanical properties of the rubberized concretes with initial compressive strength of 20 MPa was examined. The amounts of the rubber used … WebbThis new genre of concrete was produced at a lower cost than normal concrete because of the very low pre-treatment costs of the recycled wastes used. Furthermore, the properties tend to indicate that the concrete could be applied where lower strength and high durability properties are warranted.
Webbrubberized concretes fall within the range of (1543 − 1914) kg·m-3, they can be classified among lightweight concretes in classes LC 1.6, LC 1.8 and LC 2.0, respectively, according to the standard EN 206-1 [15]. With the increased content of rubber aggregate in rubberized concrete, the matrix density decreased and the open porosity WebbThe rubber waste additives in RC act as an absorber and balance all internal stresses in concrete. RCs may be used in highway construction as a (1) shock absorber, in sound …
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 …
WebbThese POFA-modified rubberized concretes displayed a satisfactory performance up to 500 °C, and superior acoustic properties in terms of sound absorption. The presence of TRA as 30% coarse aggregate replacement was found to improve the sound absorption properties by as much as 42%.
