Abstract

In-situ carbonation technology represents a form of mineral carbonation that integrates CO2 into the fabrication process of cementitious construction materials, capturing CO2 as calcium carbonate(CaCO3) through a reaction between calcium ions(Ca2+) and CO2 released during cement hydration. This investigation examines the application of in-situ carbonation technology to a variety of floor dry cement mortar formulations commonly used in local construction projects. It assesses the effects of varying the CO2 injection flow rate and total volume of CO2 injected. Additionally, the study evaluates the impact of reducing the quantity of cement used as a binder on the final product's quality.

In-situ 탄산화 기술은 시멘트 기반 건설재료의 제조과정에서 CO2를 주입하여 시멘트 수화과정에서 용출되는 Ca2+ 이온과 CO2의 탄산화 반응을 통해 CaCO3의 형태로 CO2를 격리하는 광물탄산화 기술이며, 본 연구에서는 현재 국내 건설현장에서 시공되고 있는 바닥용 건조시멘트 모르타르 배합의 범위에서 In-situ 탄산화 기술을 적용 시, CO2의 주입 유량 및 총 주입량을 검토하고, 바인더인 단위시멘트량 감축에 따른 제품의 품질 검토를 실시하였다.
