This study aims to investigate the activating effect of Na2CO3 and NaOH on the workability and mechanic strength of slag-based alkali activated materials with different alkali contents and water to binder ratios. The heat release during the reaction process of slag activated with sodium carbonate and sodium hydroxide were monitored respectively to analyze the hydration process. Meanwhile, the w...

Some factors influencing the separation and detection of amino acids by high-performance anion-exchange chromatography with integrated pulsed amperometric detection were investigated. These factors include eluent concentration, column temperature, and detection waveform. The selectivity changes in weakly retained amino acids are slight with changing sodium hydroxide eluent concentration. When s...

     This research was conducted to evaluate the nutritional value of vicia faba residues processed with some chemical compounds using in vitro and nylon bag techniques. Treatments included unprocessed vicia faba residues (control) and processed with water (2.5 lit/kg DM), calcium oxide (160 g/kg DM), hydrogen peroxide (57 ml/kg DM) and sodium hydroxide (50 g/kg DM). The chemical composition o...
