effect of clinker composition on grindability - sciencedirect

Mar 01, 1979 · Grindability data is a relative measure of the response of the clinker to the grinding force and is used to deter- mine the energy required to grind the clinker to a given specific surface. The Bond work index is the most widely used method in the U.S.A. for determining grindability, because it has been shown to give results in agreement with operating practice

Grindability and the energy consumption in clinker grinding are influenced by a number of factors as well. If it is defined as the rate of production of fine material for a given energy expenditure, then it is reasonably well accepted that grindability increases with porosity and alite content (3CaO · SiO 2 or C 3 S) [1, 2] and decreases

The motives to replace clinker with supplementary cementitious materials (SCM) are well known. However, granulated blast furnace slag, natural pozzolanes, qualified fly ash and further SCM have a limited availability; the total potential replacement of the global clinker production is less than 30%. Limestone is increasingly being used as a component in Portland-Limestone …
