The purpose of this study is to investigate the impact of leaders’ use of motivational language on psychological relatedness and its effect on employee well-being in flexible and remote working conditions.

A survey among 375 full-time working professionals in the US was conducted with varying frequencies of remote work arrangements. For the analysis, we used a series of PROCESS analyses to examine the moderating effect of leaders’ motivational language use on the relationship between participants’ remote work status and relatedness, with employee well-being as the dependent variable.

The findings revealed a significant moderating effect of leaders’ perlocutionary (direction-giving) language use on the relationship between employees’ remote work status and relatedness. Specifically, the relationship between remote work status and relatedness was stronger when the use of perlocutionary (direction-giving) language gradually increased. Such enhanced relatedness, in turn, generated higher satisfaction and psychological well-being. The study shows the strategic advantage of direction-giving language in enhancing relatedness, thereby contributing to higher levels of employee satisfaction and psychological well-being in remote work environments.

The originality of this article lies in its integration of motivational language theory and self-determination theory to explore the well-being of employees within flexible and remote work status. Furthermore, we conceptualize remote work as a continuous variable with different degrees of flexibility, ranging from occasional telecommuting to fully remote work, allowing for a nuanced understanding of how leaders’ use of motivational language interacts with varying levels of remote work arrangements to influence employee well-being.

This paper aims to investigate the bond strength of metakaolin-based geopolymer mortar with cement mortar.

The mortar-mortar bond strength is assessed by slant shear and split tensile tests; pure shear strength is evaluated by Mohr’s criterion for result validation. Metakaolin-based geopolymer mortar is cast over the cured cement mortar specimen with two levels of surface roughness: smooth or grooved interface. The influence of the alkaline solution to metakaolin ratio on geopolymer bond strength is studied. Compressive strength, ultrasonic pulse velocity, permeability and flow table tests are also performed.

The paper’s findings are highlighted as follows: (1) strong mortar-mortar bond properties achieved for geopolymer mortar in all tests and conditions and validated by Mohr’s criterion and pure shear, (2) a lower alkaline solution to metakaolin ratio achieves higher bond strength to Portland cement mortar and (3) geopolymer mortar has higher compressive strength and ultrasonic pulse velocity than cement mortar at all curing ages; additionally, it is more flowable and less permeable.

The full replacement of Portland cement with metakaolin, a more sustainable cementitious material, will contribute to the decarbonization of the construction industry.

Limited research has been carried out on the bond strength of metakaolin-based geopolymer mortar to Portland cement mortar. Also, computing the pure shear using Mohr’s circle criterion of metakaolin-based geopolymer to validate the results can be considered original.
