This paper presents the results of a series of studies on the influence of curing conditions onthe strength development of high strength concrete.The 1-,3-,7-,14-and 28-day strengths of four dif-ferent mixes of Grade 75～80 concrete,with or without pulverized fuel ash and/or condensed silica fume,under five different curing regimes were investigated.It is revealed that the curing conditions have signifi-cant influence on both the short term and long term strength development of the concrete and that con-crete mixes of the same grade but containing different mineral admixtures show distinct favour for a cur-ing regime.These results will be helpful for evaluating suitable curing methods for high strength concretewith different mix proportions.
