Dry Process for Manufacturing of Cement
The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process. The dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and alumina

Cement Manufacturing Process: What is Cement made of.
Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Cement Production
Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to dry or semidry processes. Dry cement manufacture has three fundamental stages: preparation of feedstocks, production of clinker, and preparation of cement [15,16]. (1) Preparation of feedstock.

CEMENT RAW MATERIALS
Over recent decades there has been a move away from the wet process to the more energy efficient dry process. In Europe, for example, about 78% of cement production is from dry process kilns, a further 16% of production is accounted for by semi-dry/semi-wet kilns, and only about 6% of European production now comes from wet process kilns.

Explain dry and wet process of cement manufacturing
The dry process although cheaper needs excessive fine grinding. It is more suited for the hard material (Fig 3.1) The wet process, on the other hand, is free from the dust, grinding is easier and the composition of the cement can easily be controlled.

How Long Does It Take for Concrete to Dry? Concrete Cure Times
Quick-dry uses low water and a mix of cement for quick drying while industrial concrete mixes might take longer. While the above factors can add or subtract a few hours from curing and drying time generally: Most new concrete pours can handle foot traffic in about 24 hours. Most new concrete pours can handle vehicle traffic in 48 hours.

Bulk cement
Non-hydraulic cements (e.g., lime and gypsum plaster) must be kept dry in order to retain their strength. Concrete should not be confused with cement because the term cement refers to the material used to bind the aggregate materials of concrete. Concrete is a combination of a cement and aggregate.

Concrete is mixed by adding together Portland cement, sand, and coarse aggregate (gravel) together in a ratio of 1:2:4. Water is added to the dry mixture to bind all the components together. In a concrete mixer, add the determined amount of water and then the concrete mix. You can also mix this in a wheelbarrow with a shovel.

Surface Preparation Before Applying Coatings | Concrete
By far, concrete surface preparation is the most common before applying coatings. 99% of all concrete projects have a very thin film curing agent applied to it. This helps the concrete dry without cracking when initially poured, but is an enemy to epoxy coatings. Therefore, this thin layer of silicone-based compound needs to be completely removed.
