Abstract
Influence of characters of fly ash on the fluidity of cement paste with polycarboxylic acid type superplasticizer has been investigated in connection with the particle size of distribution, unburned carbon content, specific surface area and shape of fly ash. The fluidity of paste is increased with increasing roundness of fly ash and it is decreased with increasing n-value of Rosin-Rammler distribution function. There is a linear correlation between roundness/n-value and fluidity of fly ash cement paste.
