Abstract
As one of the major materials used in construction, cement can be very resource-consuming and polluting to produce and use. Compared with traditional cement processing methods, dry-mix mortar is more environmentally friendly by reducing waste production or carbon emissions. Despite the continuous development and promotion of green construction materials, only a few of them are accepted or widely used in the market. In addition, the majority of existing research on green construction materials focuses more on their physical or chemical characteristics than on their promotion. Without effective promotion, their benefits cannot be fully appreciated and realized. Therefore, this study is conducted to explore the promotion of dry-mix mortars, one of the green materials. This study uses both qualitative and quantitative methods. First, through a case study, the potential of reducing carbon emission is verified. Then a path analysis is conducted to verify the validity and predictability of the samples based on the technology acceptance model (TAM) in this study. According to the findings of this research, to ensure better promotion results and wider application of dry-mix mortar, it is suggested that more systematic efforts be invested in promoting the usefulness and benefits of dry-mix mortar. The model developed in this study can provide helpful references for future research and promotion of other green materials.
Highlights
Many countries have dedicated more efforts to reducing anthropogenic CO2 emissions since signing of Kyoto Protocol in 1997 [1,2]
In the study on the motivation of using computers [13], it was found that perceived ease of use and usefulness of a computer system were both positively and significantly correlated with all the factors related to the use of the computer system while perceived ease of use had a significant and direct influence on perceived usefulness
It can deduced that the dimension of quality characteristics (QC) is probably helpful in improving the subject’s past experience (PE) and Perceived Ease Of Use (PEOU) of dry-mix mortar and, consequentially, improving their A and Actual System Use (ASU) regarding dry-mix mortar
Summary
Many countries have dedicated more efforts to reducing anthropogenic CO2 emissions since signing of Kyoto Protocol in 1997 [1,2]. The problem of global warming is continuously worsening while the construction industry is a major contributor to heavy pollutions and energy consumption [3]. Based on the estimation by the United Nations Environment Programme, the building sector accounts for 30%–40% of global energy use [4]. The CO2 emissions from embodied energy of construction constitute an important share of the total, indicating that building materials have a high importance which is often ignored. Traditional cement is a major source of carbon emissions among the materials used in construction. Transportation and use of cement mortar can lead to heavy air pollutions with flying particles. How to improve carbon emissions and environmental pollution problems is an issue of great importance
