Mar 10, 2019 2019 could be a proving year for the cement industry at worldwide level as the global economy is expected to face several challenges, which in turn could dampen investment in construction projects, and lead to a decline in consumption of cement.
Oct 23, 2010 Cement-based materials, such as concrete and mortars, are used in extremely large amounts. For instance, in 2009 concrete production was superior to 10 billion tons. Cement plays an important role in terms of economic and social relevance since it is fundamental to build and improve infrastructure. On the other hand, this industry is also a heavy polluter.
The concrete of the order of 200 Mpa has become a reality at least at the laboratory conditions and concrete of the order of M60 to M120 are commonly used at sites. The properties of the high strength concrete are well studied and understood by the engineers today, the use of very high strength concrete no longer raises eye brows.
Mar 12, 2019 The Danish Technological Institute works closely with industry to bring 3D printing technology into the construction industry. We first introduced the teams work back in 2017, but they have been making progress since then. The 5 Challenges of 3D Concrete Printing. The big challenge with 3D printed architecture is the material itself concrete.
Oct 20, 2016 10 Advantages of concrete. Advantages of concrete. Among all the construction materials used in the world, concrete is most widely used due to its unique advantages compared to other materials. 10 major advantages of concrete are explained below. 1. Concrete is Economical. Compared to engineered cementitious materials used for construction, the production cost of cement concrete
