Tempering metallurgy - Wikipedia

The cast iron will usually be held at temperatures as high as 1,000 C 1,830 F for as long as 60 hours. The heating is followed by a slow cooling rate of around 10 C 18 F per hour. The entire process may last 160 hours or more. This causes the cementite to decompose from the ledeburite, and then the carbon burns out through the surface of the metal, increasing the malleability of ...

Managing mortar in hot and cold weather conditions CEMEX UK

In very hot weather the main concern is the rate at which water is removed from the mortar either by suction of the masonry or evaporation. Experienced bricklayers know instinctively that on very hot days warm bricks and blocks will generally absorb more water from the mortar. The mortar will also tend to lose its plasticity at a faster rate due to the evaporation of the water from the mix.
