Abstract : More than 80 million tonnes of blast furnace slag is generated annually as a by-product of the steel industry in
China. Most ground granulated blast furnace slag (GGBS) however ends up in low-grade applications such as cementitious
materials in mortar. Blast furnace slag, ground to a suitable fineness, can be used as a partial replacement of cementitious
material in structural concrete. This paper discussed the potential for using GGBS in floor concrete slabs. With 50% of CEM
I cement replaced with GGBS, peak hydration temperatures determined in a suspended concrete slab reduced by 20%. This
beneficiary effect however has not been further improved with 70% of CEM I replaced with GGBS. Partial replacement of
CEM I with GGBS also has a retardation effect on the early-age strength of concrete, especially at an early age.
Keywords- GGBS, thermal effect, sustainable construction
