What is the chemical reaction in concrete?
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.
How does the cement hydration reaction work?
As the cement hydration reaction progresses, concrete will eventually change from a fluid to a rigid state. A possible working mechanism for SCS on cement hydration reaction and its products can be proposed, as shown in Figure 7.14.
How is concrete made?
How Concrete is Made. 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.
What happens when you mix cement and water together?
Cement and water form a paste that coats each particle of stone and sand鈥攖he aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete.
