The death rate in the construction industry, which is more than twice that of other industries, increases the need to solve chronic safety problems. In a situation in which the safety management measures that have been maintained thus far are unable to reduce construction accidents, the introduction of smart construction safety technology (SCST) that reflects the 4th industrial technology is required for the safety management of workers. Large corporations or public institutions have introduced SCST and are operating pilot sites, but SCST is still in its infancy and there have yet to exist field data regarding necessity and effectiveness. In this study, the concept of SCST, which has still to be established, is defined, and the actual condition of SCST was analyzed through a survey. Through the analysis of the necessity of SCST introduction, convenience, and effectiveness before and after its application, problems such as problems from the field point of view as well as other factors hindering the introduction of such technology are derived in detail. In addition, an effective combination of technologies for safety management at the current level is determined and an activation plan is presented.

이산화탄소 포집물을 활용한 모르타르의 플로우 및 압축강도에 대한 물-결합재비의 영향을 평가하기 위해 6배합의 모르타르 배합실험을 수행하였다. 실험결과, 모르타르의 초기 플로우 및 압축강도는 CCM 혼입율 보다는 물-결합재비에 중요한 영향을 받았다. 6 mixes of mortar test prepared to evaluate the effect of the water-binding material ratio on the flow and compressive strength of the mortar using the CO₂ capture material, Test result showed that the initial flow and compressive strength of mortar was significantly affected by the water-binding material ratio.
