CEMENT OF THE FUTURE WILL SAVE ABOUT 70% WATER
The carbonated calcium silicate cement will allow for more resistant, durable, inexpensive concrete, with reduced water consumption up to 70% and reducing greenhouse gases emissions and is already available for use in industrial units such as concrete plants, concrete precast and others.
Concrete – A combination of cement, sand and gravel – is one of the most effective construction materials in the history of mankind. Therefore, its use is so intensive, that per year are produced between 2 to 4 tons of this material per inhabitant on Earth. This manufacture is believed to be responsible for 5 to 8% of all global emissions of carbon dioxide.
The carbonated cement, also designated as “carbonated calcium silicate cement” or CCSC (Carbonated Calcium Silicate-based Cement) is characterized by reacting with carbon dioxide and calcium silicate instead of water, thus reducing the consumption of this precious resource and CO2 emissions, important objective in the cement industry.
At first glance, this new product looks like conventional concrete, but it has properties that make it last longer in some applications. For example, on roads of cold climate countries, this material has proved to be more resistant to degradation than common concrete, including direct contact with salts used for thawing, such as sodium chloride and magnesium chloride.
According to Weiss, the new cement is ready to be used in precast concrete products, which can be produced in a factory and transported to the place where they will be used. The only drawback will only be its manufacture, as the process may take longer, since carbonation requires a more complex mechanism than necessary in the manufacture of conventional concrete. While in the latter, only a single hose is sufficient to pour water on the dough, with the carbonated cement is required CO2 tanks under pressure.
Nevertheless, in view of all the above-pointed aspects, we believe the wagering of the acquisition of this innovative material, which in summary brings together the following main advantages:
Greater endurance and durability;
Lowest cost;
Reduces greenhouse gases emissions;
Improves the problem of global warming;
Reduces water consumption.
