The research of the deterioration reinforced concrete strengthening slabs of water engineering constructions

12 functioning water engineering constructions - WEC in various regions of Lithuania were selected for the investigations. The reinforced concrete strengthening slabs of mentioned WEC were investigated. Main deterioration and rupture of reinforced concrete strengthening slabs character and causes of ones are described, conditions of strengthening slabs were estimated by points. It is established that rupture of reinforced concrete structures of WEC in the time being were caused in many cases by unfit manufactured concrete, which properties do not satisfy requirements of usage; influence of aggressive environments, unfit exploitation. The data of investigations published in the article is given for improvement in designing new strengthening slabs, repairing the damaged part of construction timelyVytauto Didžiojo universitetasŽemės ūkio akademij
