A new soft computing approach for green supplier selection problem with interval type-2 trapezoidal fuzzy statistical group decision and avoidance of information loss
(Soft computing, 2020)Green supplier selection problem (GSSP) is viewed as multiple attributes group decision-making (MAGDM) issue that includes the green growth and influential factors within subjective and objective natures. Because of the ... -
A review of the best experience on crumb rubber – dry process modified asphalt mixture performance
(CETRA 2020 : 6th International conference on road and rail infrastructure, 20–21 May 2021, Zagreb, Croatia, 2021)The use of crumb rubber made from end of life tyres for asphalt mixtures modification in order to improve their properties or just utilize waste products may be considered as potential solution. Crumb rubber can be used ... -
A study of rapeseed oil-based polyol substitution with bio-based products to obtain dimensionally and structurally stable rigid polyurethane foam
(Journal of polymers and the environment, 2018)Water-blown polyurethane foams from low functionality polyols are characterized by intensive shrinkage, high density, post blowing, and longer demold time. These drawbacks can be partially, or fully, eliminated by varying ... -
A study on tannery sludge as a raw material for cement mortar
(Materials: Section: Construction and building materials, 2019)The paper analyses the properties (chemical and mineral composition, microstructure, density, etc.) of recycled tannery sludge (TS) and the possibilities for using it in cement mortar mixture. Mortar specimens containing ... -
A test road with unbound base and sub-base course from MSWI bottom ash mixtures
(Buildings: Sustainable and Green Construction Materials, 2023)A considerable amount of literature has been published on municipal solid waste incinerator (MSWI) bottom ash as a substitute for natural road materials. However, most studies are conducted in the laboratory, and as a ... -
Adding granite polishing waste as sand replacement to improve packing density, rheology, strength and impermeability of mortar
(Powder technology, 2020)Reducing waste disposal from stoneware industry and reducing use of sand in construction industry are both important for sustainable development. One strategy to tackle both problems is to utilize the waste from stoneware ... -
Adding granite polishing waste to reduce sand and cement contents and improve performance of mortar
(Journal of cleaner production, 2021)Sand and cement are indispensable ingredients of concrete but their production is causing sustainability problems. Two strategies have been adopted to reduce their consumption, namely, sand replacement with solid waste and ... -
