The pozzolanic activity of pulverized fuel ash (p.f.a.) has been determined by measuring the rate of dissolution of silica from p.f.a, in 0.I M hydrofluoric acid. The rate of extraction of silica follows a logarithmic law and the rate constant is an index of the pozzolanic activity of the ash. Die

Major oxide and component modal analyses show the composition of the pulverized-fuel ash produced over five days from each of 26 U.K. sources to remain virtually constant. Recurrent compositional differences do, however, exist between sources. These largely reflect different proportions of illite an
Twenty daily samples of pulverized fuel ash (PFA), obtained from the combustion of sub-bituminous Waikato coals, have been analysed. The contents of MgO, SOS, B203 and total and uncombined CaO in the New Zealand material were high when compared with most PFA produced in Europe and the USA. The PFA w
