VACUUM TECHNOLOGY FOR RESTORATION OF CONCRETE STRUCTURE

Abstract

This paper deals with the causes, problems and vacuum applied solutions to various concrete deterioration problems. Many companies have performed, and are presently performing, restoration of concrete structures. The methods presented here are unique method and technologies. They have applied on an array of members and structures to restore many different types of deteriorated and disrepair conditions. After explaining the basic techniques and the materials used in these various methods and processes, several applications are described to demonstrate individual successes. Cores taken after many of the in-situ restored projects demonstrate the strength increase and therefore, should provide longer life of the structure after the rehabilitation is completed in a wide and extensive range of conditions.
