Abstract:
Only few recent studies on the curing procedures applied to the HPC are available in Brazil, because it’s use hasn’t been a common practice in the civil construction industry. The present work reports the experimental production of high-performance concrete with compressive strengths ranging from 60 to 100 MPa, using materials available in the metropolitan regions of Goiania and the silica fume as a mineral addition. The specimens were exposed to five different curing conditions: 1 day of wet curing, 7 days of wet curing, membrane curing based on paraffin, membrane curing based on chloride rubber, and air storage. The results obtained for the compressive strength at 28 days indicate the different concrete performance under several curing conditions, allowing therefore a better knowledge of the HPC behavior, so that it may used safely where it is needed.
