including granulated ground blast-furnace slag by means of isothermal conduction calorimetry at five temperatures in the range 10-60oC. Their conclusion was that the total heat evolved from the slag blended cement was far greater than that of the cement at 60oC, indicating that the slag reactivity was strongly favoured by the higher temperature.

Chemistry of the blast furnace . Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates).

There are different ways in which the raw materials are charged into the blast furnace. Some blast furnaces use a "double bell" system where two "bells" are used to control the entry of raw material into the blast furnace. The purpose of the two bells is to minimize the loss of hot gases in the blast furnace.
