| Abstract | ||||
| This current paper presents an overview of the influence of adding a shrinkage inhibitor admixture (SIA) with varying contents (0,1.25, and 2.5 liters/m3), three types of cement (CEM I 52.5, SRC 42.5, and CEM III 42.5), two types of high-range water-reducing and retarding HRWR (Type G), and mineral admixture (silica fume from two different sources) on early strength self-compacting concrete fresh and hardened concrete properties, especially compressive strength. 276 cubes (150*150*150mm) containing 23 mixes were cast to investigate the effect of SIA type, Type G, and cement type on fresh concrete properties (average slump diameter), mechanical properties, and especially compressive strength. It was found that concrete cast with CEM III has the largest slump flow diameter, while concrete cast with Sulphate-Resistant Cement SRC has the least diameter. Sulfate-resistant cement has the highest T50 value, while high-blast cement CEM III has the lowest T50 value. Using high-blast cement decreased the values of compressive strength. | ||||
