    Abstract : Vattenkraften står för hälften av vårt elbehov i Sverige idag. Merparten av vattenkraftverken är gjutna i betong och som många andra betongkonstruktioner så drabbas betongen av sprickbildning av olika orsaker. För vattenkraften är genomgående sprickor ett problem då dessa skapar läckage. READ MORE
