Plastic wastes are a major hazard for the environment and their use in construction industry is increasing day by day. The drawback of plastic concrete an exceptional reduction strength workability. This research work explores effect sand coating on two types recycled aggregates, high-density polyethylene (HDPE) electronic-wastes (E-wastes), as partial replacement natural aggregates. ranged fro...
Abstract A polyester plasticizer (RSOP) for polyvinyl chloride based on rubber seed oil (RSO) was synthesized. Firstly, RSO monoglyceride were synthesized by the transesterification of with glycerol at 220–240 °C. Secondly, RSOP from and adipic acid esterification. The characterized GPC, FT-IR, 1 H NMR DSC. Plasticized (PVC) materials dioctyl phthalate (DOP) in varying ratios prepared via therm...
Abstract In this work, samples of fine-grained concrete were made with the addition TiO 2 powder in a range 1-3 wt% relative to cement. The photocatalytic properties for degradation pyrene solutions sodium dioctyl sulfosuccinate under UV irradiation investigated. To evaluate efficiency photodegradation, method luminescence analysis was used. It found that degree using reaches 25% after 120 minu...
An efficient use of plasticizers in rubber compounds requires an understanding their miscibility behavior. Besides the chemical properties both and plasticizer, rigidity plasticizer plays important role for miscibility. The is investigated here using glass transition measured by differential scanning calorimetry broadband dielectric spectroscopy (BDS). Additionally, interfacial relaxation phase...
Abstract Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather. In this context, the establishment standard assays measure rate plasticizers under varying scenarios plays pivotal role comparing durability those PVC-derived leather-simu...
This paper focuses on the modification of clay properties with inorganic additives to deflocculate and flocculate inorganic soil for the development of a material that would be as easy to use as the current concrete products, but with a much lower environmental impact. Considering that the rheological behaviour of clays is controlled by their surface charge, we first introduce potential determi...
A simple and efficient ambient ionization method based on paper spray combined with tandem mass spectrometry allows rapid detection and quantitation of various contaminants (clenbuterol, melamine, plasticizer and sudan red) in various foodstuffs (e.g., meat, milk, sports drinks and chili powder).
