Abstract:
Commercial production of Type K expansive cement in the United States dates back to 1963, however it was not until three years later that a program of field measurements was undertaken in order to recorc the actual on-site concrete expansion and subsequent net length changes in two municipal structures using this shrinkage-compensating cement.
