Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a ...
1. Introduction and research motivation. The climate problem forces the cement industry, which accounts for ~ 5–8% total anthropogenic CO 2 emissions [1], to seek for alternative binders to reduce the carbon footprint [2].The alkali-activated slag cement (AASC) show promising performance even when involving high-volume fillers with lower activity [3].

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, …
Portland cement (CEM I 42.5 according to EN197/1) with a Blaine specific surface area of 385 m 2 /kg, graded crushed granite of 20-mm maximum size and natural sand (zone M of BS 882 [9]) were used throughout this study.Three types of limestone powder and two types of chalk powder, provided by OMYA UK, were chosen and used as filler to produce SCC mixes.
