The generation of construction waste can be divided into a decommissioning phase and a new construction phase, and most of the waste is generated at the decommissioning stage. However, recently, domestic new construction construction has expanded to 150 trillion yards per year, so construction work is increasing rapidly. Especially, as the size of the construction work with much waste of construction waste exceeds 100 trillion, the management of the amount of construction waste in the new construction site is required. Unlike the dismantling work site, the new construction site can separate waste generated by each property, and relatively low foreign matter content is generated. The purpose of this study was to investigate the amount of construction waste generated by new construction sites and to calculate the unit amount of construction waste based on this. In addition, since the existing unit cost is centered on concrete and mixed waste, we set the basic unit by setting synthetic resin, waste wood, and waste board as additional items. The basic unit survey was carried out to investigate the wastes according to the characteristics of each construction period. As a result of the survey, the new construction site showed that most wastes were discharged in the first 30% and after 70% of the process, and the ratio of mixed construction waste was as high as 45%. As a result of this study, it was found that about twice as much waste was produced as compared with the conventional standard product.

This study addresses the analysis of the behavioral characteristics of bridge expansion joints under wheel loading through wheel load test and the proposal of relevant wheel load specifications for expansion joints. To that goal, specimens of rail and finger expansion joints that are widely used in Korea were fabricated and subjected to static wheel load test using a real tire wheel. The wheel load distribution factor in the rail and finger expansion joints in contact with the wheel load was evaluated. The evaluation revealed that the portion of load sustained by the central rail of rail expansion joint was decreasing with larger wheel load, and that the portion of load sustained by the finger expansion joint was practically insensitive to the increase of the contact area and remained nearly constant. Since the wheel load characteristics showed large difference compared to former design specifications, it appears necessary to prepare rational specifications relative to the distribution of the wheel load contact pressure for the design of expansion joints.

In the production of high-strength concrete of 80 MPa or more, silica fume is widely used as a binder to ensure the strength safety and pumpability of concrete. The bulk density of silica fume is an important physical property that can have a significant impact on the performance of concrete. Therefore, Understanding the effect of silica fume density on the physical properties of concrete and selecting the appropriate material with the correct density is crucial to ensuring optimal performance in construction projects.

대형건설현장 공사가 아니면 그만큼 지원이 적을 수 있고, 또 공기도 충분히 확보하기 어려울 수 있다. 그런 면에서 이들 현장의 무재해는 매우 어렵다고도 볼 수 있다. 최근 이같은 편견을 보기 좋게 깨나가는 현장이 있다. 바로 LG데이콤 수원사옥 신축공사 현장이다. 이곳은 기본에 충실한 안전관리와 안전을 최우선 가치로 여기는 현장의 안전마인드로 이러한 각종 악재들을 극복해왔다. 이곳 현장의 준공일은 3월 18일이다. 대형공사현장도 쉽게 이룰 수 없다는 무재해 현장의 기록에 성큼 다가서 있는 'LG데이콤 수원사옥 신축공사'를 찾아 그동안의 안전정책과 현재 마무리 과정이 어떻게 진행되고 있는지 살펴봤다.
