This paper describes an experimental investigation of the behavior of self-consolidating concrete (SCC) produced and cured under conditions of hot weather, in the context of manufacturing control specimens. Two different designs were tested, incorporating either OPC or slag cement. Mechanical properties and physical properties (porosity, water absorption) were quantified in the hardened state. Notably, in the case of SCC incorporating slag cement (CEMIII), results show that an increase in the mix temperature from 20°C to 50°C did not imply the use of extra water to keep the flow properties constant at the end of mixing. In addition, the increase in both mixing and curing temperatures did not have an adverse effect on the compressive strength or porosity for any of the concretes studied, but caused a significant increase in the total creep of concrete incorporating slag cement when it was mixed and cured under hot weather conditions.
