Properties of Hardened Concrete with Blast Furnace Slag

Therefore, to avoid uncertainty in the strength and durability, concrete incorporating more than 30% slag is cured for longer period compare with concrete with no slag. Finally, the extension of slag concrete curing time is based on number of factors including ambient temperature, amount and types of cement, the temperature of utilized cement, and percentage of cement replacement.

Strength and Durability Properties of Granite Powder Concrete

The concrete with 10% fly ash exhibited higher early strength followed by an excellent development of strength over time (Haque & Kayali, 1998). Hence, it is expected that the incorporation of silica fume in concrete with fly ash and slag as a partial replacement of cement could contribute the high strength concrete.
