Full Answer. Factors such as rainfall, sunlight, wind and humidity are all contributors. Treatment of newly poured cement depends greatly on the weather conditions as moisture imbalances can cause cracking as the cement dries. Concrete will cure harder and stronger if it is allowed to dry slowly.

The primary difference among the four cement plant processes is energy consumption. The wet process, which feeds raw material to the kiln as a slurry, averages GJ/metric ton ( MBtu/ton) of cement compared to dry process with preheater and precalciner which averages GJ/metric ton ( MBtu/ton) of cement. The weighted average for all four
highly alkaline, but the setting process is exothermic. As a result, wet cement is strongly caustic and can easily cause severe skin burns if not promptly washed off with water. Similarly, dry cement powder in contact with mucous membranes can cause severe eye or respiratory irritation. II. STAGES OF CEMENT MANUFACTURING
This method has been used to a moderate extent in Germany. It is necessary to pass the granulated slag under a strong magnet in order to remove any particles of metallic iron. Blastfurnace slag is used in makingfour classes of cement—. Puzzolan, or ordinary slag cement, usually simply called slag cement.
Cement is made by crushing and grinding calcium carbonate (limestone), silica (sand), alumina and iron ore in appropriate proportions and heating the resulting mixture in a kiln to approximately 1,500°C. In the more modern "dry process" used by around 80% of our plants, the ore mixture enters the kiln dry as opposed to the older process in

May 24, 2019· Dry cement powder. The cement manufacturing process is completed when the cooled clinker is ground once again in a rotating finishing mill. A combination of gypsum and limestone will usually be added in small amounts to the heated cement during this last grinding step, and coloring agents can also be added here.
The production of cement is an energyintensive process. Annually the cement industry spends over 1 billion energy purchases. The production of cement results in the emission of carbon dioxide from both the consumption of fuels and from the calcination of limestone. This report briefly describes the various stages in the cement production process.
