Hot Weather Concreting

Combinations of high temperatures, strong winds and low humidity can lead to problems with concrete placement and finishing, especially during the summer months.

The Cement Concrete & Aggregates Association (CCAA) have released a data sheet called “Hot-Weather Concreting” to assist concreters to overcome these problems including:

• Consider placing concrete during the cooler parts of the day, or postpone the job until conditions improve.
• Ensure you have enough equipment and manpower to place the concrete quickly.
• If placing on crusher dust or roadbase, wet it down well beforehand.
• Minimise adding water on site.
• Use an evaporative retarder (aliphatic alcohol). The evaporative retarder should be applied with a fine mist sprayer as soon as the concrete is placed. Each time the surface is "broken" during the finishing operations, the evaporative retarder should be re-applied.
• Use sunshades or windbreaks where possible.
• It is essential that all surfaces are kept continually moist by curing the concrete. Curing should be undertaken progressively and start immediately after each section has been finished. Curing methods include ponding with water, use of wet hessian or cotton mats, continuous spray mist, covering with plastic sheeting or sprayed-on curing compounds.
