To provide a cargo space air slide structure of a cement carrier which achieves satisfactory transportation performance within the cargo space of the cement carrier, and satisfactory machining performance owing to a short weld length, and which avoids occurrence of cement accumulation (residue) in the space between a hull structure under a mountain-shaped cement accumulation and the air slide, thus causing no load admixture.

A canvas 2 inclined from a ship side to a mid portion of the hull is laid without any space over the entire surface of the cargo space bottom of the cement carrier. A cement distribution mountain for introducing cement into individual cutting gates is placed at the mid portion of the hull.
