In this paper, the effect of adding recycled glass powder (RGP) as a third component in polymer modified bitumen is studied. RGP and styrene butadiene rubber (SBR) is added to the base bitumen in order to prepare modified binders and mixtures. The initial study is performed to determine physical properties of unmodified, SBR modified and RGP-SBR modified asphalt binders which prove RGP's compat...

since reusing waste tire as a cheap filler is considerably high, in this study, recycled rubber to replace nr/br is used up to 15 phr and the positive and negative aspects of the rubber powder and reclaimed rubber in the physical, dynamical and processing properties are evaluated. the results showed that in the presence of recycled rubber, the cure rate, crack growth resistance, tear strength a...

This paper presents the results of investigation carried out to improve the mechanical toughness of cement mortar. Toughness is a basic parameter which has to be improved in brick walls, concrete roads, machine foundations, dams etc. Materials fails due to an impact force and vibrations resulting in minor cracks and bonding failure between bricks, it leads to failure of the structure. In order ...

in this study, shelf life properties of tomato powder under effect of air drying temperature were studied. the qualitative determination was observed that acceptance of color, aroma,flavor, and appearance at 70oc is better, so best temperature was 70oc for producing of tomato powder. tomato powder after drying ,were stored into three kind of packaging including thin cellophane, thick cellophane...

Abstract Concrete is one of the most extensively utilized building materials that can be produced, and has potential to release a significant quantity CO 2 into environment. In this research, through studying lightweight (LW) concrete, attempts are made produce environmentally friendly LW concrete with high strength using nanosilica rather than part cement waste glass powder instead aggregates....

With the rapid development of construction and industry, demand for mortar as a building material is also increasing. economic society, glass products have been widely used, manufacturing enterprises produced hundreds tons fragments slag. The main component silica, which has potential to be used an auxiliary cementing material. Therefore, waste expected recycled in buildings achieve sustainabil...

Abstract Several attempts upon inclusion of industrial waste materials such as fly ash, silica fume, GGBS, metakaolin and copper slag in concrete have already been experimented that exerted a significant impact on with enhanced mechanical improved durability properties. There were numerous authentic researches reported the significance steel fibers strengthening flexural property concrete. The ...
