Limestone (LS) powder is commonly used in concrete from the last two decades as it is widely available and having low cost. Since, LS powder is mostly used as a replacement of cement for avoiding the CO2 emission; however its incorporation in concrete may influence the shrinkage behavior of the cementitious system mainly by filler and nucleation effect. Therefore, in this paper, the effect of ...
