Concrete is a basic building material needed for many Civil Engineering projects. There is a great deal to this subject, from the types of different concrete mixtures, to curing concrete, methods of recycling it and more. Read articlees on concrete technology: how it’s made, what types are in use today and more.
Concrete is a basic building block of our everyday world. It’s used in almost every type of structure that we build today. This engineering guide to concrete will give you a variety of information about concrete, including some best practices for various situations.
Slipform construction is an economical way of working with the concrete. It works well for any kind of construction, be it working with plain concrete, reinforced concrete, or pre-stressed concrete. Accuracy and continual casting for constructing a monolithic structure are its greatest advantages.
Precast concrete is easy to work with, but its performance against earthquakes does not live up to the expectations. Frequent failure of precast concrete beam to column connections and other precast concrete beam components have put a question to its earthquake resistant strength.
Prestressed concrete pipes have lower construction costs and are more readily repaired in comparison to conventional concrete pipes. Repair of prestressed concrete pipes, in fact, has made things easy for repair and maintenance engineers.
Without curing, concrete is just like brittle mixture of various construction ingredients that can break down under excessive loads or even under normal loading conditions. Concrete under water curing, curing concrete below freezing and extremely hot temperatures needs special attention.
Proper preparation of the surface is the most important factor in achieving the bond between Ardex and the concrete surface being treated. No matter which topping or overlay is used to level, smooth, or repair a substrate’s surface, it will only be as strong as the surface to which it is bonded.
Concrete signs, as seen in office parks and public spaces, are permanent markers. Letters can be raised or inset into the concrete. Footer design details must include allowing for wind and erection stresses. Pole and sign concrete calculations must also consider erection stresses.
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 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
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.
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.
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.
It is not difficult to make concrete countertops for your home. This article is based on some easy tips to make concrete countertops.
With advancing technology, there are several options available for sealers for concrete countertops. You can find the best sealer for concrete countertops if you have some good information about them.
This article will discuss different types of concrete cracks. After finishing the article, you will know how to repair concrete cracks.
Formwork systems are widely being used in the construction industry, including bridge decks. The creation of structural elements by the formwork systems has greatly benefited the construction industry.
Glass fiber reinforced concrete is an engineered material that contains cement, polymers, and glass fibers that are ingrained in the cementious matrix. The GFRC properties are influenced by the glass contents, mix design, and production process. GFRC is mainly used for external applications.
Exposed aggregate concrete is normally used for terraces and walkways. It consists of the small stones fitted inthat improves the look and the strength. The common methods of its production are Surface Dressing and Washed to Expose.
The applications for decorative concrete are increasing significantly, since the appearance of conventional concrete is changed radically by alteration into decorative concrete. Decorative concrete is used in modern expensive homes and also in small economical homes.
Concrete is required to be poured for formation of the desired shape. The general techniques used for form work is timber shuttering that is a customized temporary structure, retained till the concrete sets and gains strength. Road forms are shuttering that can be repeatedly used.
