| Lightweight When compared with structural grade concrete, vermiculite concrete is 15% of the weight. This results in considerable savings from the footings through the structural steel. Insulation | Ease of Application Vermiculite insulating concrete is easily placed by modern, specially designed pumping equipment. Up to 25,000 square feet can readily be placed in one day. Fireproof | Versatile Vermiculite concrete can be applied over a variety of bases, allowing architects and engineers ample flexibility in their design criteria. The thickness of the concrete can be varied to permit necessary slope to drain |

Have you ever wondered how concrete is made? Well, this article describes all the details you need to know about making concrete!
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.
Within this process lies the key to a remarkable trait of concrete: it’s plastic and malleable when newly mixed, strong and durable when hardened. These qualities explain why one material, concrete, can build skyscrapers, bridges, sidewalks and superhighways, houses and dams.
The words of this article are not what is the most important. Watching the first slabs of concrete get poured on video is the eye magnet. Watch the slabs of concrete at work by going and reading/watching this article.
With the changes in the economy its hard to find the right time to improve your home. Although with the drop in concrete material costs this may be the best time to do some of those landscaping projects you had in mind.
