EXPERIMENTAL INVESTIGATION OF HIGH STRENGTH CONCRETE WITH ALCCOFINE OF M65 GRADE CONCRETE

Abstract

This article presents the results of an experimental study conducted to evaluate the mechanical
properties of a high strength concrete with alccofine. High strength concrete is manufactured by partially replacing
cement with alccofine and fly ash. In this study, fly ash was used in a constant proportion of 20% and alccofine at 0, 6,
8, 10, 12 and 14% by weight of cement. The proportions of the concrete mix had a constant binder/water ratio of 0.25
and a superplasticizer was added depending on the degree of workability required. The concrete samples were cured in
normal wet curing at normal atmospheric temperature. The results indicate that concrete manufactured with these
proportions generally has excellent hardening and freshness properties since the combination is somewhat synergistic.
The addition of Alccofine shows an initial property of strength gain and that of fly ash a long-term resistance. It has
been found that the ternary system consisting of ordinary Portland concrete, fly ash and alccofine, increases the
mechanical properties of concrete at any age compared to concrete made with fly ash and Alccofine alone.
