This makes radiant floor heating in concrete slabs ideal for both commercial and residential applica. We know almost all objects expand when heated then goes back when the heat is removed. In hot weather conditions AS 1379 requires that concrete temperatures at the point of delivery shall be within a range of 5C to 35C. Concrete expands slightly as temperature rises and contracts as temperature falls. In conditions hotter than 77F the water used to hydrate and cure the cement can evaporate increasing the concretes temperature and presenting problems such as weakness. If you intend to install concrete in temperatures around 90 degrees youll need to adjust the mix and installation process to accommodate the heat.
Ideally the temperature should remain within 50 to 60F for most of the day.
Also make sure that nighttime temperatures dont drop below 40F as this may cause the water in.
