Pouring Concrete: 8 Step Process (with Pictures)
Step 1 - Site Work. Before concrete can be poured, the site needs to be prepared to reduce the chance of heaving from expansive soils and frost. On small projects, use hand to tools to clear the area of all grass, rocks, trees, shrubs, and old concrete, exposing bare earth. Earth moving equipment speeds up the process, especially for …
Cast-In-Place (CIP) Concrete
In its simplest form, cast-in-place (CIP) concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland or blended 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 ...
Concrete vs. Cement: Key Differences Explained
Concrete is a common building material, but cement is not. Cement is a key ingredient in concrete, and the average batch of concrete is typically 15% cement. Cement on its own doesn't really have many applications. It dries too quickly, and while it's a great adhesive, it isn't nearly as strong as concrete.

'Cement' vs. 'Concrete': Are they the same? | Merriam-Webster
'Cement' vs. 'Concrete' This distinction is not a new one; we have citations from over a century ago in which writers take care to observe (or admonish) that concrete and cement are not synonyms (the reasoning being that cement is one of the parts of concrete).. But cement is not concrete, so another trial was made, by forming blocks of the latter …
Concrete Buying Guide
The terms concrete and cement are often used interchangeably. However, the two aren't the same product. Cement is the main ingredient in concrete and acts as a binder.
