Abstract: Self curing concrete (SCC) is a new trend on construction industry. Flat plates are the most commonly used slab system today for multistory reinforced concrete hotels, hospitals, and apartment houses. In this investigation the focus will be on the effect of the reinforcement ratio and the effect of central square opening size on the behavior of self curing reinforced concrete flat slabs, This goal is achieved through the studying the structural behavior of ten RC tested slabs. The experimental program was carried out on ten reinforced concrete plate of (120 x 120 x 7) cm resting on four supports and subjected to concentrated load. The load was applied gradually in increments to record the first crack load, the failure load and the deflections at each load increment. Comparative study between the experimental results and previous research on high strength concrete slabs were performed. Self curing concrete flat slabs were recorded higher cracking loads than high strength concrete flat slabs. Deflections recorded from SCC were greater than deflection recorded from high strength concrete slabs.
