In order to quantitatively evaluate the effect of fly ash (FA) as partial replacement of cement on the life-cycle environmental impact of concrete, a comprehensive database including 4023 laboratory mixes and 2120 plant mixes was analyzed. The environmental loads on the life-cycle assessment were quantitatively converted into environmental impact indicators through categorization, characterization, normalization and weighting process. The life-cycle environmental impacts of concrete could be classified into three categories including global warming, photochemical oxidant creation and abiotic resource depletion. Furthermore, these environmental impacts of concrete was decreased with the increase of the replacement level of FA and governed by the unit content of ordinary portland cement (OPC). As a result, simple equations to assess the environmental impact indicators could be formulated as a function of the unit content of binder and the replacement level of FA.

Large amounts of waste shells have been produced each year from shellfish raising industries located in Korean costal areas. Due to the limited space for the waste shell disposal, the related environmental problem has been a serious issue. It is believed that using the waste shells as a source of aggregate for mortar, concrete or bricks can be a good solution. In this research, possibility of utilizing waste shells as an aggregate of mortar is investigated. Waste shells of manila clam, cockle, clam, sea mussel, and oyster were properly crushed, sieved, and sorted to meet the requirements of the grading of standard fine aggregate. After that, the waste shells were used as partial and total replacement of the fine aggregate, and their absorption and 28-day compressive strengths of mortar were measured. In general, replacement of waste shells increased the absorption and decreased the strength. However, one specimen with cockle increased compressive strength as replacement ratio increased. Mortar with cockle of 50% and 100% replacement showed higher compressive strength than that of control mortar. This increase of compressive strength was found to be affected by the strong interfacial bonding properties of the cockle and a cement matrix.

Recently, the amounts of dredge sea soil in south Korea have been increasing because of various maintenance works at harbors and rivers. Dredged sea soil contains various contaminants. Hence, prior to recycling the dredged sea soil, the various contaminants should be removed to prevent a secondary contamination due to the leaching of hazardous chemicals. Pretreated dredged sea soil can be buried under the ground or used for land reclamation. In this study, however, pretreated dredged sea soil was used to investigate the level of pozzolanic activity. The properties of pretreated dredged sea soil were investigated, the method for heat treatment was determined, and the compressive strength of mortar using dredged sea soil was examined. According to the XRF result, the main components of dredged sea soil were
of over 55%, and
of some amounts. Results from XRD and TG/DTA showed that pretreated dredged sea soil can be used as a pozzolanic material. When dredged sea soil was thermally treated for 90 min at
, a compressive strength result was similar to that of control mortar.

As environmental matters such as Green House Effect rise, many construction industries are putting an effort on minimizing environmental impact in terms of building life cycle throughout the world. However, in South Korea, evaluating the eco-friendly building based on life cycle assessment has been facing an academic ostracism while the most studies are focusing on assessing the 6 environmental impact assessments of passive apartment based on life cycle assessment. The theoretical consideration of the life cycle assessment and environmental impact category were performed and the direction of the study was set up. Also, existing apartment and passive apartment, which had same structure and same type were chosen and building materials per unit area were compared to find out the difference environmental impact for building life cycle. As a result, passive apartment was rated as low level among the 6 environmental impacts. Also, effect of building material on passive apartment was more important than its operational stage.

Fast-tracking was developed as an optimizing method to shorten the duration of construction project in 1960`s, and it introduced to Korea in 1999. Since then, many Korean companies have been used fast-tracking for getting economical benefit from shorten duration. However, there were some problems(dispute, delay and cost overrun) because of using inappropriate subcontractor management system. For this reason, previous studies suggested some management models to solve these problems. Unfortunately, however, the models have been had some doubts about reliability, objectivity and possibility of using them on real construction site. Therefore, this study suggests 3 steps of strategic subcontracting method and apply it on real fast-tracking practice(L company) to secure reliability and objectivity. Through this, the method is expected to make up the doubts of previous studies.

In construction site, BIM is used in part of construct-ability review and design mistake checking. However, in a current domestic construction site, except public order project, most of work in private order project has been processing based on 2D work. As an expert resists to certain point in introduction of new technique, it may be shown in the introduction of BIM. For this, We need to analysis construct-ability of introducing BIM, work field of introducing and operational capability about present domestic construction engineers. Therefore, this study solves the problem of existing construct-ability analysis, and it visualizes the various information and objects for an effective job performance. Furthermore, construct-ability analysis by BIM that can use an intergrated management is theoretically examined and practical field-application priority among conclusions is proposed through a survey targeting on the hand-on worker. Therefore, this study suggests a factor supplying for a business-centric introduction plan and support condition.

Jeong, Mingu ; Kim, Gwang-Hee ;
Journal of the Korea Institute of Building Construction, volume 14, issue 6, 2014, Pages 583~590
DOI : 10.5345/JKIBC.2014.14.6.583
The purpose of this study is to analyze and compare the life cycle cost of window glass with insulation film and regular glass, to verify an economical window construction method. As an approach method, the thermal performance data of each type of glass was measured using Window 6.3 and ECO2-OD Simulation Program, applied it to the case building to calculate the air conditioning and heating maintenance costs and LCC, and compared the economic feasibility. As a result, installing an additional insulation film prevents the solar heat penetration in the summer, so it reduces the cooling cost, on the other hand, it increased heating cost in winter. From the life cycle cost perspective, the effect of cooling cost reduction does not counterbalance the increase in heating cost and the additional cost from film installation and repair; therefore, the installation of insulation film may not be a proper method.

Shin, Seungil ; Lee, Ung-Kyun ; Cho, Hunhee ; Kang, Kyung-In ;
Journal of the Korea Institute of Building Construction, volume 14, issue 6, 2014, Pages 591~596
DOI : 10.5345/JKIBC.2014.14.6.591
This study investigates the perception of the sunken costs of an urban development project, which is currently a social problem through a questionnaire survey. The results indicate that local and federal governments, political authorities, association members, landowners, etc. partially recognize their responsibility in bearing the sunken cost. It is also found that all stakeholders who participated in the maintenance project felt shared responsibility of bearing the sunken costs and exchanging solutions to mitigate the same, rather than making one party deal with the same. This study also suggests that with regard to reducing these sunken costs, the public sector should offer indirect support (by bearing the cost of infrastructure, tax benefits, regulation relaxation, etc.) rather than direct support so that the association members can make a reasonable choice on the project execution.

Recently proposed intelligent images are generating, storing and managing along with existing image information and 5W1H information. Therefore, these vector images can be useful in searching and managing photos taking during building construction and maintenance processes. In addition, when the vector photos, a key to the intelligent image, is linked with BIM, it is possible to find BIM objects by utilizing information included in vector photos. And if the taken vector photo is saved as attributes of the extracted object, the vector photo can be managed as the historical data. Furthermore, this new technology will contribute to make the management of construction information more efficiently. This study is about the development of the technology of extracting BIM objects from vector photo information and managing the attributes of the extracted objects. Also the prototype modules was developed and tested to evaluate the processes of setting reference points, converting coordinate system, calculating positions, and so on. Through these processes, it was confirmed that the possibility of extracting BIM objects from vector photos and of managing attribute data of objects.

DOI : 10.5345/JKIBC.2014.14.6.615
This study suggests the design and assembly drawing of the prefabricated precast concrete arch ammo magazines using the numerical analysis as well as the explosion verification test. The protective capacity of the proposed magazines is identified with the maximum support rotation angles measured by explosion verification tests according to the U.S. Unified Facility Criteria 3-340-02. Using numerical analysis, it is examined that oval-type members are better than the semi-circle ones in terms of protective capacity. Based on this numerical results, the design and assemble drawing for the prefabricated precast concrete arch ammo magazine are developed. It is identified that the structure constructed by invented design and assembly drawing has enough protective capacity against blast pressure caused by 133.75kg TNT explosion. The detonation point cannot be open due to the military security. In sum, it could be concluded that the ammo magazine proposed in this study has reliable protective capacity with enough redundancy. The redundancy means that there are more economic design approach with reducing the curved wall thickness.

Recently, following the application of modular housing techniques to not only residential sector, but also to business sector, the scope of modular housing market b expanding. In the case of other developed countries, such markets are entering into the maturity stage, though the market in Korea is not fully formed yet. Thus, it is difficult to check its trend to estimated mid- to long-term prospects of the market. In this context, the study predicted demand of the modular housing market by using a non-linear prediction model based on time series analysis. To get the prospects for the modular housing market, the quantity of housing supply was estimated based on the estimated quantity of newly built housings, and assumed that a portion of the supplied quantity would be the demand for modular housings. Based on the assumption of demand for modular housings, several scenarios were analyzed and the prospects of the modular housing market was obtained by utilizing the non-linear prediction model.

For the construction materials, concrete, as the most widely used material, is focused on its improvement of performance. Although concrete has many advantages of easiness of handling, economical benefits, and high compressive strength, low tensile strength, brittleness and drying shrinkage are reported as the drawbacks of concrete. Hence, to solve these drawbacks of concrete, many research has conducted especially using fiber-reinforced concrete technology. Especially, HPFRCC which has high volume of fiber reinforcement was suggested as a solution of these drawbacks of normal concrete with increased ductility while it has the possibility of workability loss with fiber clumping which can cause low performance of concrete. Therefore, in this paper, optimized fiber combination with either or both metal and organic fibers is suggested to provide better performance of HPFRCC in tensile strength and ductility. As the results of experiment, better workability was achieved with 1 % of single fiber rather than multiple fibers combinations, espeically, short steel fiber showed the best workability result. Furthermore, in the case of organic fibers which showed higher air content than steel fibers, higher compressive strength was achieved while lower tensile and flexural strength were shown.
