ABSTRACT
A large proportion of the foamed concrete industry is very interested in alternating the AAC block. As a result, deliberate attempts to develop the sustainable foamed with low CO2 emission and low energy consumption have been increasingly made. In particular, considerable efforts for safe and sound recycling of by-products including Ground Granulated Blast-furnace Slag (GGBS) have been enacted in the foamed concrete industry because the CO2-emission coefficient of Ordinary Portland Cement (OPC) from a Life Cycle Assessment (LCA) is commonly evaluated to be 0.8 to 1.0 ton-CO2/ton. To address these issues, the present study examined the fundamental properties of foamed concrete with the addition of GGBS as a
partial replacement of OPC. The measured properties of the prepared foamed concrete were compared with the ASTM strength class (ASTM 2012).
