Rat trap bond is a kind of brick masonry wall in which bricks are laid in a vertical position instead of the traditional horizontal position. This arrangement creates a hollow space in the wall. It is also known as the Chinese brick bond. In this arrangement, shinner and rowlock are visible on the face of … Read more
Non-threaded strong joints that are normally made of steel or aluminum of head and sank is known as Rivet. Riveted joints Riveted joints are the joints that are perpetual, comprising of fundamentally two parts that are controlled together by the bolt, head at the top, and tail (barrel-shaped stem) at the base. Types of Riveted … Read more
Plaster is the composition of lime, water, and sand. Sometimes gypsum is used instead of lime. It is used for coating walls, columns, beams, ceilings, etc. Why do we do Plastering? There are three primary purposes to apply plaster on any surface. It protects the surface from harmful safety and health hazards such as rain, … Read more
This article is all about the difference between distemper paint and emulsion paint. Distemper paint and emulsion paint are the most popular choices to paint walls. Both types of paints have their own characteristics. Distemper paint is normally used for temporary structures while emulsion paint is used for permanent structures. Let us discuss distemper paint … Read more
There are various types of defects that can occur in plastering. These defects occur on the plastered surfaces due to the bad quality of plastering work. These defects in plaster ruin the complete aesthetics of the building. Plastering defects should be attended timely to avoid any structural defects such as corrosion on the reinforcement bar. … Read more
Grillage Foundation Grillage foundation is used to bear heavy structural loads from the columns, and beams. Heavy loads are needed to transfer over large areas. Grillage foundation avoids deep soil excavation because of load transfer over the large area. The typical depth of the grillage foundation is restricted from 1 meter to 1.5 meters. Grillage … Read more
RCC beam can be classified as balanced, under-reinforced, and over-reinforced sections based on the percentage of reinforcement it has. In this post, I have discussed the balanced, under-reinforced, and over-reinforced beam sections. Balanced Beam Section Reinforced concrete beam (RCC) sections in which the tension steel also reaches yield strain at the same time as the … Read more
In a doubly reinforced beam, reinforcement is provided in the tension zone and compression zone. (as shown in the above figure). The moment of resistance can not be increased by increasing the amount of steel in the tension zone. It can be increased by making the beam over-reinforced but not more than 25 percent on … Read more
Ferrocement is a thin reinforced concrete in which the cement mortar is reinforced with small diameters of steel wire meshes spaced closely. Mortar provides the mass and the steel wire mesh gives tensile strength and ductility to the structure. This system shows high tensile strength to weight ratio and good cracking performance. It is also … Read more
Underpinning is a procedure used to repair, strengthen, or increase the depth of an existing foundation by lowering the footing to permit it to rest on more supportive soil. In this technique, a new foundation is built under the old foundation, or the old foundation is repaired. Methods of Underpinning Pit Method Cantilever needle beam method Pier and beam … Read more
