High alumina cement paste, in the presence of silica fume, shows an increasing strength trend even at 20Β°C and 4O"C, since this pouolan causes the formation of gehlenite hydrate (C2ASHS) and therefore strongly reduces the transformation of hexagonal aluminate hydrates (CAHlg, C2AHS) into the cubic h

The experiments undertaken by Professor Collepardi and his colleagues(') have demonstrated that calcium aluminate (high alumina) cement containing condensed silica fume (csf) shows an increasing compressive stmngth trend at 20Β°C and 40Β°C for water/solids ratio 0.4, unlike the situation where pulveri

This work presents the relationship that exists between pozzolanic activity in certain materials (opaline rocks, fly ash and silica fume) and hydration heat, measured using the Langavant calorimeter method. Pozzolanic activity is evaluated using an accelerated method that establishes the reaction sp
