비활성 황토의 치환율에 따른 비소성 시멘트 모르타르의 내산성 및 성분 분석 = Acid Resistance and Component Analysis of Non-sintered Cement Mortar According to Replacement of Non-Activated Hwangto

다국어 초록 (Multilingual Abstract)

Globally, there are environmental problems because of greenhouse gas emissions. The CO₂ emissions rate of the cement industry is very huge, and a continued demand for cement is anticipated. In order to reduce the environmental impact of CO₂ emissions from cement production, this study conducted experiments for the development of non-sintered cement (that has not undergone firing or burning) using granulated ground-blast furnace slag, high-calcium fly ash, and nonactivated hwangto (that has also not undergone firing burning). One experiment used acid resistance and a pH test due to durability, and it conducted a component analysis for the measurement of crystalline analysis and a scanning electron microscope at the mortar. From the experimental results, the mechanical and chemical properties were compared with those of ordinary Portland cement for applicability to construction sites. In the future, to solve the problem through continued research, it will be necessary to reduce cement’s environmental load and involve an economic analysis.
