Recently, cement-based cast-in moulds which need no removal after concrete is cast, are being increasingly utilized in building construction in order to achieve labor-saving and work rationalization. Since such forms need to be thin and light for effective use in small-scale construction sites equipped with only small cranes, they must inevitably be made of materials with high bending strength. In this paper, the strength development of cement-based materials with various mix proportions are experimentally examined. It is shown that high-bending-strength cement-based materials can be obtained when low-water-binder-ratio materials with portland cement and granulated blast furnace slag as binders and sulfonated melamine formaldehyde condensate (SMF) as an admixture are steam-cured at high temperatures.
