how concrete is made - cement

In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete

Aug 30, 2012 · Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide

how cement is made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process

Jul 09, 2020 · CEMENT MANUFACTURING PROCESS BASED ON MIXING TECHNICS Based on the technic adopted for mixing raw materials the manufacturing process of cement is divided into wet process and dry process. Wet process is normally used now a days. But dry process is also gaining popularity due to their energy efficiency and when the ingredients are hard

In the production of concrete, the pre-mixing of cement and water to form a cement slurry is known. Following the production of the slurry or cement paste, it is then normally added to aggregate (sand, gravel or both) to produce the concrete mix

A novel apparatus and process for producing cement slurry on a batch basis is disclosed. During the charging of a slurry batcher with water and cement, the cement dust so produced is captured and added back to the slurry being batched in order to minimize health and environmental hazards created by the cement dust. This is achieved by passing or venting entrapped air and dust in the batcher

Wet Process and Dry Process Wet Process. The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker
