As well as the many architectural benefits of using eco₂cem, the lighter colour achieved is of benefit in areas where improved visibility is required.
Concrete is additionally being used to fill an aesthetic role in modern construction. As concrete is more frequently being used in green buildings, concrete made with eco₂cemis lighter in colour and easier to get a superior finish.
Eco₂cem has the added advantage of supressing or eliminating efflorescence.
Eco₂cem is a near-white powder. It imparts a lighter, brighter colour to concrete, in contract to the stoney grey colour that is achieved with Ordinary Portland Cement (OPC).
The near-white colour of eco₂cempermits architects to achieve a lighter colour for exposed fair-faced concrete finishes, at no extra expense. In order to achieve the lighter colour of concrete, eco₂cemis usually specified at 50-70% replacement levels.
Eco₂cem provides a cost neutral real alternative for those seeking a high quality light coloured finish. Eco₂cem is also a finer powder than OPC which allows a smooth more defect free surface to be achieved.
Eco₂cem is available from ready-mix concrete producers across Netherlands and Belgium.
Efflorescence, is one of the most persistent, insidious problems affecting concrete appearance.Efflorescence, or the staining of concrete surfaces by calcium carbonate deposits, is one of the most persistent, insidious problems affecting concrete appearance. However using eco₂cem can eliminate this problem.
Eco₂cem results in a denser, much less porous concrete. Eco₂cem enters in chemical reaction with lime, absorbing water and produces silicates, therefore any lime in solution is unable to make its way to the surface of the concrete. Eco₂cem is effective in preventing efflorescence when used at a replacement level off 50-60%.
