high strength fresh leachates generated at a new disposal trench, compost plant and partially stabilized leachate of an older trench were characterized in terms of anaerobic degradation at laboratory batch scale at 35oc. fresh leachate had extremely high cod of 66,710 – 89,501 mg/l along with low ph of 4.1-5.9 in contrast to older and therefore partially stabilized leachate with a cod of about ...

The performance of reactive powder concrete (RPC) is much higher than that ordinary concrete, and the engineering application gradually increasing. bond failure process slip between RPC reinforcement will show new characteristics. It necessary to study behavior steel bar. direct drawing test was carried out on 36 bonding specimens in order bar concrete. research shows cohesive force consists th...

The quality of grouted sleeve has a significant influence on the performance splice. Incompactness infilled grout is inevitable in grouting. To investigate tensile behavior splice sleeves due to different compactness, monotonic tests connectors were performed at compactness 100%, 90%, 70%, and 50%, respectively. bond-slip analytical model rebar-grout was deduced by fitting test data, formula fo...

The relationship between chloride ion concentration and pH on de-passivation of steel rebar embedded in concrete was investigated by a two frequencies impedance measurement using probe electrodes. A saturated calcium hydroxide solution used for the electrolyte as simulated pore solution. pair electrodes, which simulates rebar, immersed prepared an arbitrary ions, performed. Air supplied to simu...

the purpose of this study is to investigate the influence of cross-cultural communication (ccc) on stakeholder management process (smp) in international construction projects from the turkish stakeholders’ perspective. the research is based on a survey of turkish stakeholders (contractors, consulting engineers, insurance brokers, and financial advisors) operating internationally. the useable su...
