Industry Best Cement Testing with Vicat Consistency Apparatus

Building a towering building requires laying a solid foundation that will support its structure before erecting it. Most of the time, this foundation is constructed with concrete not without the help of vicat apparatus. However, does the type of concrete make a difference? Without a doubt. Imagine the Burj Khalifa, which rises to an amazing height of 828 meters and weighs approximately 450,000 tons. In comparison to the cement used for laying the foundations of our homes and apartment buildings, the cement used in the world’s tallest building differs a lot. A concrete foundation used for residential construction would not be able to support the enormous weight of the Burj Khalifa. 

A strong understanding of concrete quality in such grand constructions leads us directly to today’s discussion: the tools necessary to ensure it. We proudly present our latest advanced products, the Automatic Vicat Apparatus and the Manual Vicat Apparatus.
