By-products related to fuels NMR spectroscopy. Structural characterization by elemental analysis, FTIR, and NMR spectroscopy on both vacuum-distilled and air-blown pitches showed that distillation of lighter fractions, reduction of atomic H/C ratio, and dehydrogenation raised their softening points

Recycled poly(ethylene terephthalate), PET, mainly recovered from plastic beverage bottles, can be used to produce unsaturated polyester resins. In turn, these resins can be mixed with inorganic aggregates (sand and gravel and fly ash waste), to produce polyester concrete (PC). The strength and dura
In this paper, the fresh properties, dielectric properties and temperature profile of fly ash-based geopolymer mortars are investigated to observe the effect of mixture proportions and time after mixing. Sodium hydroxide (NaOH) and sodium silicate (Na 2 SiO 3 ) were used as the activators. The resul
We proposed to tackle the problem of fly-ash pollution from municipal solid waste incineration as well as sludge from chemical-mechanical polishing, by partial substitution of cement in mortar. The optimal modified cement mortar determined by the Taguchi method showed unexpected strengthening effect
