The category for waterproofing is one of construction process most affected by falling-off in price competitiveness, construction quality, and material performance. Therefore, in order to select of waterproofing construction firms, it is necessary to consider Incorporating both price competitiveness and construction quality. In this article, I would like to analyze 10 Factors for Selecting using fuzzy-AHP model, including the survey of the waterproofing experts. This fuzzy-AHP model can be shown to calculate the fuzzy trigonometrical function to reflect weights for preference of 10 factors for the waterproofing construction firms. It was found from the result that waterproofing construction firms was searched order of priority for select by fuzzy-AHP model.

The Present that environmentally friendly policies at issue in the world recently, construction sector and other sectors are working on reducing CO₂. Cement production during in the construction sector, CO₂ is being caused in large quantities. Therefore, this study was secure the basic date that not use cement and use blast furnace slag and fly ash HFA, polysilicon in industrial byproducts about cement non-cement matrix.

Most of the construction adhesive may contain harmful component to the human body with an organic adhesive. In addition, when the adhesive caused hydroquinone, alkyl benzophenone, etc, also it raises the skin diseases to workers. Therefore, the inorganic adhesive development is necessary. This study was a study to know adhesive strength properties that adhesive using a magnesium oxide according to the addition ratio of the retarder. It has experiments to two types of magnesium oxide and type and ratio of retarder differently.

In recent years, active loess cement has been used instead of cement in order to reduce the amount of cement and industrial byproducts that are the main cause of environmental pollution. We also used polysilicon sludge as a by-product to reduce the amount of cement used and to improve the environmental pollution due to the reduction of carbon dioxide. Polysilicon is a raw material used in the production of panels for solar power generation. When producing 1 ton of polysilicon, 2 tons of sludge is generated. It is an experiment to reduce sludge treatment and cement usage. This study analyzed basic characteristics of polysilicon sludge and active loess cement according to replacment ratio.

Researches for the development of renewable energy as a fuel substitute for global warming and depletion of petroleum resources are actively being carried out. Among them, the annual growth rate of PV generation is 20.73%, which is higher than other renewable energy sources. However, the production of 1 ton of polysilicon, which is known as a raw material for solar power generation panels, generates 2 tons of waste. As the demand for PV panels increases, the problem of the treatment of polysilicon sludge is attracting attention, and studies on the utilization of polysilicon sludge are needed. Therefore, in this study, the applicability of polysilicon sludge treated as industrial waste to the lightweight panel for architectural purposes was examined.

As the use of cement increases with the development of modern society along with the increase of buildings, environmental pollution intensifies and researches on industrial byproducts are continuing. Research on blast furnace slag and fly ash as industrial byproducts is increasing, and research on industrial byproducts such as polysilicon sludge and paper ash used in this study is increasing. Blast furnace slag, which is one of the industrial byproducts, has been widely studied as a material used with cement. However, in this study, we fabricated lightweight matrix of polysilicon sludge and paper ash replaced based on blast furnace slag, and performed SEM analysis.

In this application study, field pilot tests were performed to evaluate the validity of a proposed formula between the exerted electrical energy and SPT N-value based on the result of the basic study. Measurement sensors and recording system were developed to obtain exerted motor current and drilling depth in a field. By using the correlation formula proposed in the basic study, the measured motor current and boring speed were applied to predict SPT N-value and the predicted N-values were compared to SPT N-value of site exploration. From the comparisons it is verified that the exerted electrical energy to bore ground might be used to predict SPT N-value and pile tip location.

본 연구에서는 활성황토 혼합 시멘트와 폴리실리콘 슬러지를 활용한 경화체의 기초물성 평가를 위한 실험을 진행하였다. 산업부산물의 재활용과 환경오염에 대한 문제를 해결하고자 폴리실리콘 슬러지의 활용방안을 제시하였으며, 폴리실리콘 슬러지 치환율에 따른 페이스트와 잔골재 첨가율에 따른 모르타르의 특성을 분석하였다. W/B 및 PS 치환율이 증가할수록 강도 및 밀도는 감소하는 경향을 보인다. 잔골재 첨가율에 따른 모르타르의 밀도 및 흡수율은 잔골재의 첨가율이 증가할수록 밀도는 감소하는 경향을 보이며, 흡수율은 증가하는 경향을 보인다. 잔골재 첨가율에 따른 모르타르의 유동성 및 공기량은 잔골재의 첨가율이 증가할수록 유동성은 감소하는 경향을 보이며, 공기량은 증가하는 경향을 보인다. 잔골재 첨가율에 따른 모르타르의 휨강도 및 압축강도는 잔골재의 첨가율이 증가할수록 감소하는 경향을 보인다.
