Concrete Info

Lightweight Concrete Information

Advantages & Features

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
Vermiculite concrete has excellent insulating properties. Three inches of vermiculite concrete is equivalent to 1-1/2 inches of rigid board insulation layered over steel decks. One inch of vermiculite concrete is equal in insulating value to 20 inches of regular

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
recognized nationwide by insurance companies, state rating bureaus and local building officials. Underwriters’ Laboratories have assigned up to 4-Hour ratings to systems that employed vermiculite as one of the components.

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

How Concrete is Made

Have you ever wondered how concrete is made? Well, this article describes all the details you need to know about making concrete!

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.
