Influence of Environmental Temperatures on the Concrete Compressive Strength: Simulation of Hot and Cold Weather Conditions

The research described in this article focuses on developing and defining industrial applications of ready-mix concrete. That is, the researchers report on their work investigating the influence of mixing hour on the properties of concrete, such as workability and compressive strength, under hot and cold weather conditions, with a view towards industrial application. The variable focused on was the concrete mixing hour, and five different mixing hours were used for each type of weather condition. Three batches of concrete were prepared for each mixing hour, and the compressive strength of 15 cylindrical concrete specimens was measured after 7 and 28 days. Hydration kinetics of each batch of concrete was also studied on the basis of the mixing hour and the climatic conditions. Results indicate that for compressive strength, the concrete's best mechanical performance occurred when there was less difference between ambient temperature and concrete temperature, meaning during the later hours of the day in hot weather conditions. In other words, it is advised that in hot weather conditions, concrete should be placed in the later hours of the day when the ambient temperature decreases. In cold weather conditions, one should place concrete in the early hours of the day when the ambient temperature rises.
