Abstract:The excellent performance of a large industrial floor, built in Buenos Aires with a Shrinkage-Compensating Concrete, made with Ordinary Portland Cement and an expansive agent, created an interest in applying this solution in other parts of Argentina. To establish whether the solution was also applicable elsewhere, it was required to investigate the effect certain relevant local conditions might have on the behaviour of the Shrinkage-Compensating Concrete. For that purpose, an experimental programme was conducted, aimed at studying the effect variables such as cement type, expansive agent dosage, temperature of the concrete and curing conditions have on several relevant properties of the Shrinkage-Compensating Concrete. The investigated properties were: restrained expansion and shrinkage, compressive strength and coefficient of air-permeability. The experimental results showed that the combination "blended cements + expansive agent" presents advantages compared to the combination "OPC + expansive agent". The results of the investigation were put into practical use for the construction of a large industrial floor in the City of Rosario, Argentina, where a Shrinkage-Compensating Concrete made with Portland-Slag Cement and an expansive agent was used with excellent technical results and with economic benefits too.
