Self-Compacting Concrete (SCC) is highly useful in congested reinforced structures where vibration or compaction prove difficult. It's a concrete that can flow, consolidate under its own weight and completely fill the formwork without further vibration. In this research, laboratory investigation of SCC mix prepared from three different recipe set of aggregates (20mm, 12.5mm, and 10mm) down size and mix designed for 1: 1 1 /2: 3 mixing proportion with w/b ratio of 0.56 and Sulphonated Naphthalene Formaldehyde dosage (1.2% by weight of cement) was affirmed based on field trial. The SNF acting as Super plasticizer (Water Reducing Agent) and influence of the admixture was examined via the workability tests. However, it was examined by using the slump flow test, V - flow, and L - box test. The designed mix achieved consistency and self compatibility under its own weight without any external vibration or compaction. 150mm x150mm x 150mm cube specimen cast was done and thereafter cured for twenty eight (28) days. The strength development for each of the specimen at 3, 7, and 28 days for the respective mix was examined and the results showed that increase in the compressive strength with respect to the curing age, enhancement in workability, reduction in shrinkage, and bleeding of the concrete mix of SCC holds to the inclusion of Super Plasticizer in the mix. The significance of this research work lies in its attempt to provide information on the performance of Self Compacting Concrete made from different recipe sets of aggregate and its major advantage in salvaging time and labour. Keywords: Aggregate, Curing, Self-Compacting Concrete (SCC), Sulphonated Naphthalene Formaldehyde, Plasticizer, Strength, and Workability.
