In the construction industry, there are numerous pros to using extraordinary powerful concretes. Not only do workers find that they are a lot simpler to pump, but they also lay and compact much nicer than traditional concretes. To go with these positives, there are negatives. One such con is that they may not be as strong and as durable as the conventional concrete. However, one does not need to despair. In September in London, the Admixtures Symposium was sponsored by the Concrete Society. Master Builders Solutions specialist Oliver Mazanec was present to talk about what causes concrete to do this and the various ways one can prevent it through different stabilizers.
Cement is the main element when structures crush previous records. All buildings need concrete to be constructed properly. This goes for the highest structure in the world- Burj Khalifa in Dubai. Or the tallest residential area on the planet- 432 Park Avenue in New York City, New York. Others that are remarkable to see may include Taipei 101, Dancing House — Prague, Czech Republic, Château Frontenac — Québec, Canada, Willis Tower- Chicago, Illinois, Shanghai Tower- Shanghai, China, and St. Basil’s Cathedral — Moscow, Russia. Every single one of these structures was constructed differently with various methods to maintain their durability and be durable.
There are various challenges that can be faced when it comes to the construction industry and dealing with various materials. The cement that is chosen for the job must be super hard, self-compressed, and needs to be able to be pumped over a great distance. Many times, concrete that has all three of these properties flows very well but separates. Due to this, there will be a reduction in strength and it will not be as durable. This is why Oliver Mazanec has made it a priority to add stabilizers to prevent the separation of the concrete. It will also stop the bleeding process, which can be seen when the water is released from the mixture when not desired.
Depending on how the concrete will be used will depend on how the construction workers apply it. A key element is a structural viscosity when concrete is pumped a lengthy distance. This often happens when skyscrapers are being built. The concrete must be flowing in order to do the best job. The best way to describe this is that an immense shear rate is used for low viscosity. The viscosity will be turned up instantly when the shear rate is turned down. This will make the concrete sturdy while it is stable in distribution. Recently, Master Builders Solutions revealed a new commodity MasterMatrix SCC 210- a shear-thinning admixture that will allow the properties to be controlled. This product was showcased for the first time at this conference.
Heights can present a huge challenge in the construction world when it comes to concrete. Mazanec recommends using MasterMatrix SDC 100 from Master Builders Solutions to stabilize products. If the aforementioned isn’t used, once the cement is placed, the substance at the base will be exposed to very high pressure. This will make the concrete bleed, or makes water escape. Once the product is cured, it will not have the strength that it would have had if the water had remained.
Using stabilizers in your construction work is like using fall protection. It is something you and your employees need to make sure your work is successful each time. Just as you would call Beam Runner for anchors and other forms of fall protection, you would call Master Builders Solutions for a stabilizer.
