Since a large amount of waste polyester-cotton blended textiles can cause environmental pollution problems,it is crucial to develop sustainable technology for recycling textile wastes and producing valueaddedproducts. In this research, regenerated cellulose and polyester were obtained from thepolyester-cotton jean wastes by a sustainable process through the selective dissolving of cellulose fibersusing an ionic liquid (ILs), 1-butyl-3-methylimidazolium chloride ([Bmim]Cl). We developed an environmentallybenign decoloration approach without the bleaching or leaching processes. Instead, cellulose,polyester, and ILs were recycled from the selective degradation of indigo carmine (IC) or indigo dye inthe dye/ILs solution using the Bi11VO19 photocatalyst without impairing the dissolution capability ofILs. The selective decoloration of dye solution extracted from waste textiles involves interactions amongphotocatalysts, colorants, fibers, and media (ILs). The changes of dye and ILs molecules during the photocatalysisreaction were analyzed. FTIR and Raman spectra of the recycled ILs reveal that the chemicalstructure of ILs remains unchanged after the photocatalytic decoloration process. The ILs and photocatalystscan be recycled for repeated production of regenerated cellulose from waste jeans.
Experimental investigation on steel-concrete bond in lightweight and normal weight concrete

The bonding behaviors of Lightweight Aggregate Concrete (LWAC) and normal weight concrete were investigated experimentally. Pull-out tests were carried out to measure the bond strengths of three groups of specimens with compressive strength levels of 60, 40, and 20 MPa, respectively. Test results showed that the difference in the bond failure pattern between LWAC and normal weight concrete was significant as the concrete compressive strength became lower than 40 MPa. The corresponding bond strengths of LWAC were lower than that for normal weight concrete. As the compressive strength of concrete became relatively high (> 40 MPa), a bond failure pattern in normal weight concrete occurred that was similar to that in LWAC. The bond strength of LWAC is higher than that for normal weight concrete because it possesses higher mortar strength. Stirrup use leads to an increase of approximately 20% in nominal bond strength for both types of concrete at any strength level.
