The pozzolana cement industry is capital-intensive therefore, it needs significant investment over the long term. It is vital for manufacturers to establish plants in close geographical links between cement production and mining sites in order to reduce costs and transportation time for carrying raw materials. Hence, the pozzolana cement.
The above advantages of Portland pozzolana cement have been attributed due to the slow conver173sion of calcium hydroxide CaOH 2 in the hydrated cement paste into cementitious product. In one of the recent studies in an ordinary Portland cement paste only 20 calcium hydroxide was found after 1 year hydration where as in a similarly hydrated paste containing 30 pozzolana, only 8.8 calcium.

This paper presents the experimental results of the fineness effect on the pozzolanic activity of Cu-Ni slag in cemented tailing backfill. Cement paste and cemented tailing backfill samples that without or contain Cu-Ni slag with various grinding times were made and cured at 20176C for 7, 28, and 150 days. Mechanical test and microstructural analyses are performed.
Synopsis. Backfill stabilised by portland cement has been widely used in cut-and-fill mines. However, the cost of using portland cement tends to increase the cost of backfill and this has led to mine operators considering the use of pozzolans as partial replacement of portland cement.
