Influence of active mineral admixtures on fatigun bihavior of concrete

Abstract

     We used active admixture with the rate ≤ 30% to produce CVC which release low temperature to make bulk concrete (up to 30%-70%) to produce RCC. This article focus on the effects of the active mineral additives to the fatigue strength of the concrete which includes 30%-50% fly-ash (mass fraction) or 30%, 50% and 80% blast furnace slag (used for the fatigue test). The results of the fatigue strength to crack of the concrete are up to 2000000 period of the bending load. Mineral admixtures can exert beneficial effect on hi-cycle fatigue behavior of concrete for the improvement of transition zone, as for low-cycle fatigue behavior of concrete effect of mineral admixtures depend on their influence on concrete strength..
