Purpose - This study examined the relationship between dyadic relationship between leaders and followers (DRLF), distributive justice (DISJ), job satisfaction (JSTC), and organizational commitment (OGCM). Research design, data, and methodology - 200 sets of survey questionnaires were distributed to the employees at a municipal office in East Malaysia using purposive sampling technique. Only 60 percent or 115 questionnaires were returned to the researchers. The survey data were analysed using the SmartPLS due to its ability to deliver latent construct scores, handle small sample size problems and estimate relationship between many constructs in the hypothesized model. Results - The findings indicated that there is a significant correlated direct relationship between DRLF and DISJ and mediating relationship between DRLF, DISJ and personal outcomes, which are JSTC and OGCM. Conclusions - This study confirms that DISJ does act as an important mediating variable in the relationship between DRLF with JSTC and DRLF with OGCM. Other dimensions of personal outcomes, such as extra-role behaviour, job motivation and service quality should be considered in future study because they are found to be the important outcomes of the relationship between DRLF and DISJ. The importance of these issues need to be further advanced in future research.

This paper studies the early-aged chloride binding capacity of various blended concretes including OPC(ordinary Portland cement), PFA(pulversied fly ash), GGBFS(ground granulated blast furnace slag) and SF(silica fume) cement paste. Cement pastes with 0.4 of a free water/binder ratio were cast with chloride admixed in mixing water, which ranged from 0.1 to 3.0% by weight of cement and different replacement ratios for the PFA, GGBFS and SF were used. The content of chloride in each paste was measured using water extraction method after 7 days curing. It was found that the chloride binding capacity strongly depends on binder type, replacement ratio and total chloride content. An increase in total chloride results in a decrease in the chloride binding, because of the restriction of the binding capacity of cement matrix. For the pastes containing maximum level of PFA(30%) and GGBFS(60%) replacement in this study, the chloride binding capacity was lower than those of OPC paste, and an increase in SF resulted in decreased chloride binding, which are ascribed to a latent hydration of pozzolanic materials and a fall in the pH of the pore solution, respectively. The chloride binding capacity at 7 days shows that the order of the resistance to chloride-induced corrosion is 30%PFA > 10%SF > 60%GGBFS > OPC, when chlorides are internally intruded in concrete. In addition, it is found that the binding behaviour of all binders are well described by both the Langmuir and Freundlich isotherms.
