limestone powder decreases the UHPC compressive strength. The decrease is directly proportional to the added amount of the limestone powder. At this high strength level, its chemical bonding (if any) is inferior to the main matrices with silica fume. Therefore, it may be considered that the limestone powder functions like a filling material. 0 ...

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 ...
