Concrete Technology
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.
Engineering Guide to Concrete: Best Practices
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.
Working with Concrete: An Insight into the World of Concrete Building Construction
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 Beam to Beam, Beam to Column Failures
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.
In-situ Repair of Prestressed Concrete Pipe
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.
Concrete Curing Underwater, in Freezing and Hot Temperatures, and in Humid Conditions
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.
Using Ardex Concrete Resurfacer for Overlays
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 - Making the Footer for a Concrete Sign
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.
Testing for Cement Content in Concrete Slabs and Samples
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 Reinforcement of Masonry Walls - Feasible but is it Practical?
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
How to Make Air Entrained Concrete - Air Entrained Concrete Testing
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.
