Durability performance of sustainable self compacting concretes in precast products due to heat curing

Heat curing, which is used to ensure the production rate, influences the microstructural and durability properties of the concrete. When a given performance is required, the influence of the heat curing in the concrete properties must be considered in the concrete design process. This paper evaluates the influence of heat curing on several parameters of two self-compacting concretes (SCC) produced in laboratory and at industrial scale, one of them designed based on sustainable issues (replacing 20% of cement with limestone filler). The obtained results show that the heat curing process modifies the properties of both concretes in a similar way thus more sustainable heat cured SCC can be fabricated.
