本研究は、軽量気泡コンクリートブロック（LFCB）における水代替材料としての炭酸の効果を密度と熱伝導率に焦点を当てて調査した。適度な濃度の炭酸は炭酸塩結晶の成長を促進し、材料の多孔性を低下させるが、高濃度では逆効果となる。結果は炭素中立建築に向けた将来の研究の基礎を提供する。
English
This study examines the effects of carbonic acid as a water replacement in lightweight foamed concrete blocks, focusing on density and thermal conductivity. Moderate concentrations of carbonic acid promote carbonate crystal growth, reducing porosity and improving insulation, while high concentrations increase thermal conductivity. The findings aim to fill knowledge gaps in construction materials and support future carbon-neutral building research.

In the global GX context
In the global context, cement production accounts for ~8% of CO2 emissions. This paper explores carbonation as a means to improve building material properties while potentially sequestering CO2, contributing to the growing literature on low-carbon concrete and sustainable construction relevant to global decarbonization pathways.

📄 Abstract（原文）
Cement production’s rising emissions of greenhouse gases, especially CO₂, are a major cause of environmental alarm. Concerning that, this study examines the effects of carbonic acid on Lightweight Foamed Concrete Blocks (LFCB), with an emphasis on its density and thermal properties. It aims to investigate the impact of different carbonic acid concentrations on the density and thermal conductivity of LFCB, as well as the relationship between these variables. Modest levels of carbonic acid appear to promote the growth and connection of carbonate crystals in the concrete matrix, which, in effect, creates a less porous material and insulating ability. Higher concentrations result in larger pore sizes and structural changes that can generate higher thermal conductive materials. The carbonic acid shows as a derivation of density and thermal conductivity (principally till 50%) when there is an optimal density for normal LFCB blocks. Meanwhile, at this stage of concentration, it can lead to an increase in density and thermal conductivity. The results aim to fill the knowledge gap for the construction behaviour of LFCB as a material and provide a reference for future research on carbon neutrality in buildings.
