Abstract
In the buildings, where reinforced concrete floor slabs are subjected to the action of aggressive liquid environment due to the technological process, reinforced concrete structures have small remaining life and technical condition of them is close to inadmissible one, that causes necessity of repair works or reconstruction. Instrumental inspections of the precast reinforced concrete flat floor slabs under the action of lactic acids show, that slabs have numerous defects and damages: deep corrosion of rebars and concrete, failure of support ends of the slabs. The main elements of floor slabs are in bounded functional condition or inadmissible condition at the parts The constructive solutions on reconstruction of the floor slabs by construction of a new slab are suggested. These solutions consider technological loading on the floor, stability of columns, rigidity of a building frame during the construction, change of a floor level.
