Testing for Cement Content Cement content in any concrete has a direct relation to the strength of the concrete, its durability and impermeability. For tests for cement content and other forms of concrete testing, standards have been laid down which need to be adhered to by civil engineers.
Shotcrete for Reinforcing Masonry Walls? Shotcrete is the application of concrete to any surface through mechanical means using pneumatic appliances. It avoids the use of formwork, and ensures faster work. Shotcrete reinforcement of masonry walls can increase life of walls but would require consideration of shotcrete velocity and shotcrete
Use and Production of Reinforced Concrete Combining the hardness of the concrete with the flexibility of the steel, reinforced concrete makes modern construction possible. This article discusses mixes and production, including dosing, casting, launching, and curing.
Benefits of Air-entrained Concrete Air entrained concrete has microscopic air bubbles in the concrete. Air bubbles provide durability for concrete exposed to freezing and thawing. These air bubbles help to improve the workability of the concrete and reduce the slump. Concrete entrained air testing is a must to maintain quality.
Why Does Concrete Crack? Cracks are one of the most common defects in concrete. This article will discuss the four main reasons for concrete cracking and how concrete surface cracking can be avoided.
Concrete Roads vs Asphalt Roads Asphalt roads wear more than concrete roads, but many countries are replacing concrete roads with asphalt because it is cheaper, despite concrete roads having some major advantages. Learn about the advantages and disadvantages of the different road paving surfaces in this article.
Useful Calculations for Concrete This article provides several useful calculations for concrete, such as the concrete cubic yard formula, concrete weight calculations, and a bags of concrete calculator formula.
Roman Concrete Technology What the Romans taught us about concrete could fill a fairly thick book. The Romans learned that low water content and compaction are the keys to making extremely durable structures like the Pantheon, which still stands after 2,000 years.
