Prestressed concrete is the most extensively used form of structural concrete beside conventional reinforced concrete. In process of prestressing, we enhance the tensile strength of the structural element like a slab or beam. We introduce tensions steel wires or cables that induce compression in the concrete. We do this process before applying the external load … Read more
Cyclonic precipitation is a type of precipitation that results from lifting of air masses converging into low pressure area in the atmosphere. Cyclonic precipitation as the name suggests is a result of cyclonic activity. It’s a concept that is bit different from the conventional rainfall or conventional precipitation. In conventional precipitation, the rainfall happens as … Read more
A weep hole is simply a vent through the top or center of masonry or retaining wall. The primary purpose of weep holes in retaining walls is to allow drainage through the joints (or between panels) of the wall during wet weather. The slots also provide a positive indication that the wall is not completely … Read more
Fiber-reinforced concrete also referred to as FRC is a type of concrete that contains fibrous material to improve structural strength. It is made up of short distinct fibers that are evenly dispersed and orientated randomly. The fibers we use in concrete are small distinct piece of reinforcing material that possesses certain characteristic properties. In general, … Read more
A tie beam is a structural beam that connects two columns at any height higher than the floor. The term “tie”, which refers to its purpose, is used to connect two columns or other structures. Tie beams can be used to reduce the effective length of columns and to decrease their slenderness ratio. Primary and … Read more
A reinforced concrete beam that is placed between the foundation and wall is called a plinth beam. Plinth beams are used to stop cracks from extending from the foundation into walls above, when foundation settlement is occurring. Plinth beams evenly distribute the wall’s load over the foundation. What is plinth Beam? A plinth beam is … Read more
Injection grouting is a technique of repair used to fill up gaps, cracks, voids or annular spaces between joints in concrete walls, masonry or underground structures. Injection grouting is carried out with a specialized type of grout material that is filled under pressure and set hardened according to the shape of void or crack. We … Read more
Apart from the length as the obvious difference between a short column and a long column, other differences are there. So, today’s post is about short columns vs. long columns. Definition of column A column is a vertical element of a structure that transfers compressive loading. Designers provide it in all frame concrete structures. It … Read more
The compaction factor test is done to check the workability of concrete, on the basis of weight ratio between partially compacted to fully compacted concrete. We can’t use the slump test for low workable concretes. Concretes we mostly use in mass dam structures or road pavements have significantly low values of slump. For all such … Read more
So, you’re wondering what is lean concrete? Well, concrete mix made from lean concrete is low in cement and high in aggregates. It is used for several purposes, such as blinding concrete under foundations and leveling pads below footings. We call lean concrete “not rich.” That’s because it is not rich in cement. Cement is … Read more
