We are in the middle of the dog days of summer. Not only are Ohio's hot days tough on the contractors, these high temps are hard on ready mix concrete. When the concrete temperatures rise the reaction of the cement in the mixes is accelerated. This makes for significantly faster set times. The chances of a pour running away from you is much higher. Our only choices are to work very hard and very fast (not easy and probably dangerous for the workers) or to add retarder to the loads. We believe that bang for the buck retarder is one of the best admixtures we have. Not only does retarder slow down the initial set process, it also provides other benefits including higher final strengths.
When the temperatures are high, adding retarder will help you provide a quality product to your customers while making your life a little easier.
