    Improving Concrete Durability by Using Optimized Aggregate Gradation and Reducing Cement Content by Chung, Hung-Wen

    Published 2020
    “…The main findings from this study are as follows: (1) The cementitious content of typical Florida pavement and structural concrete can be reduced by as much as 10 to 15% without loss in workability of the fresh concrete, and without decreasing the strength and durability of the hardened concrete. (2) Portlandlimestone cement (Type IL) can be used as a substitute for ordinary Portland cement (Type I/II). (3) The OAG technique can be used to efficiently reduce the cementitious content of the concrete mixes and to improve their performance."…”

    Enhanced bioelectrochemical treatment of petroleum refinery wastewater with Labaneh whey as co-substrate by Mohanakrishna, Gunda

    Published 2020
    “…Among several concentrations of LW as co-substrate in the range of 5–30% (v/v) with PRW, 85:15 (PRW:LW) showed to have the highest power generation (power density (PD), 832 mW/m2), which is two times higher than the control with PRW as sole substrate (PD, 420 mW/m2). On the contrary, a maximum substrate degradation rate of 0.420 kg COD/m3-day (ξCOD, 63.10%), was registered with 80:20 feed. …”
