Title: Effects of High Fineness and Large Amounts of Ground Granulated Blast Furnace Slag on Properties and Microstructure of Slag Cements

Abstract:Describes test results obtained on the heat of hydration, strength development, hydration products, pore structure, and combined water of blended cements with high fineness and large amounts of ground granulated blast furnace slag (GGBS) and discusses the relationship between them, comparing them with ordinary portland cement (OPC) and blended cement with smaller amounts of GGBS. The following conclusions were drawn from this study. 1. The heat of hydration of blended cement with over 70 percent content of GGBS reduces significantly. The blended cement incorporating a large amount of GGBS with high fineness can have the properties of lower heat of hydration and relatively high compressive strength required for massive concrete generally used in Japan. 2. The blended cement with high fineness and high content of GGBS results in a more compact pore structure than OPC due to the formation of finer hydration products.
