How Concrete is Made - Portland Cement Association

The water-cement ratio is the weight of the mixing water divided by the weight of the cement. High-quality concrete is produced by lowering the water-cement ratio as much as possible without sacrificing the workability of fresh concrete, allowing it to be properly placed, consolidated, and cured.

How Long Does it Take for a Bag of Quikrete to Dry?

If you're pouring concrete outside, weather conditions and air temperature also influence how quickly the concrete goes through the curing process. Ideal conditions for curing concrete would be in warm temperatures (around 70°F). Take into account, however, that the hotter the air temperature the faster the curing/drying process.

Dry process of cement - we civil engineers

These are two different processes of manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substance.Both the processes are in use and have their own advantages and disadvantages.While in wet process grinding is easier,in dry process there is a saving in fuel costs involved in drying up the slurry.
