These additives, combined with hot water can provide set times typical in the summer months during the late fall, winter and early spring. Using accelerators provides time savings to the contractor. Since time is money, accelerators provide the best option for getting the job done quickly.
Heated water increases the temperature of the concrete which improves the setting time of concrete for cold days.
We offer chilled water during the summer for projects with specific temperature requirements.
