Abstract: The present disclosure relates to a “concrete slotted floor” manufactured from an UHPC composition which exhibits superior crack resistance due to uniform distribution of reinforcing fibers even when a residing surface is located below, allows early demolding due to fast initial setting time and exhibits improved cleaning efficiency due to maximized surface water repellency, an “UHPC composition for manufacturing the same” and a “method for manufacturing a concrete slotted floor using the same”.
