Influence of Fly Ash Content in Cement Paste on Size of Creep

The cement paste is basic part of concrete and can contain a various additives. Fly ash is one of the materials useable as an admixture in the cement paste and concrete. The changes of properties of the cement paste mixed with fly ash were observed during several months. Creep of dried and saturated cement paste was measured for one complete month. The preparation of the cement paste and specimens is described in paper, too. From tests were obtaining two different kinds of data, about water dried and saturated specimens. The measured data was evaluated and compared with results of computational model with a creep model B3.
