How Climbing Formwork Makes Concrete Construction Easy? Climbing formwork is a special type of formwork that rises along with the progress of vertical concrete construction. It can move on its own by using an electric or hydraulic jack. Such formworks are also called self-climbing formworks. It is an effective solution for structures requiring seamless wall units or for high-rise structures with repetitive forms. A climbing formwork is employed for a project based on the type of building units constructed. It remains in place during the process. A fully self-climbing formwork system is generally used for constructing structures with more than 20-floor levels. This article explains some of the important features and benefits of climbing formwork in construction. Components and Assembling of Climbing Formwork The main components of climbing formwork are: Suspension platforms Wall formwork material and pieces Anchor system Climbing brackets The general components of a climbing formwork ar

  How to Install Corrugated Asbestos Cement Roofing Sheets? Asbestos cement sheets are popularly used as a low-cost roofing material. The improved properties attained by the addition of asbestos in cement make it suitable to be used for insulation, fireproofing, roofing, and flooring jobs. In this article, we’ll discuss the specifications for laying and fixing of corrugated asbestos cement roofing sheets. Figure-1: Corrugated Asbestos Cement Roofing Sheet in Industrial Buildings Laying  of Corrugated Asbestos Cement Roofing Sheets The sheets are laid on the purlins and other roof members as indicated in the working drawings or as instructed by the engineer. The maximum spacing of purlins under the sheets shall be 1.40 m for 6 mm thick sheets, and should not exceed in any case. The ridge purlins shall be fixed at a distance between 75 mm to 115 mm from the apex of the roof. The top-level of all purlins and other roof members shall be in one place so that when the sheets are fixed, it sh

  Measurement of Masonry Brick Works in Construction including Deductions Measurement of masonry works in construction is required for calculation of quantities of materials in masonry and to measure completed work. Masonry works are those where cement and fine aggregates without any coarse aggregates are used for construction purpose. There different types of masonry work Brick Masonry Concrete block / brick masonry Stone / rubble masonry Clay tiles, etc. Measurement of Masonry Works: Masonry works are such as brick masonry, concrete block, stone or rubble masonry are generally measured in volume, but are also measured in terms of area where the thickness of masonry is limited to single brick or single block. Tiling is measured in area. While measuring the quantities of masonry work, the wastage of materials such as bricks, cement or sand is not taken into account. Also, the types and classes of bricks, blocks or tiles are not considering while measuring the quantity of work. This is

  Overlay Concrete for Crack Repair in Concrete Structures Overlays are surface depositions of 6 mm or greater in thickness that can be bonded, partially bonded, or unbonded to the surface of the concrete.  The material of overlay may be polymer concrete, Portland cement concrete, epoxies, polyesters, and polymer-modified concrete. Overlay concrete change the appearance, texture, and elevation of the original concrete surface and a variety of different colors and finishes are available. Overlays may bridge nonmoving cracks, but the active cracks may appear again. Overlays are used as a wearing course, provide protection against the intrusion of water and chloride ions, provide abrasion resistance, and may be decorative. Overlays are useful to seal areas with large number of cracks, where individual treatment of each crack is too expensive. Overlays used to seal active cracks must be extensible (must have the ability to elongate and shorten). It is important to note that the cracks are

  Top 7 Tiles for your Bathroom Floor A variety of bathroom floor tiles are available in the market of which the most common ones are vinyl, ceramic and porcelain. Selection of best floor tile for the bathroom is dependent on certain factors like budget, the overall architecture of the building and the expected wear and tear. Above all, understanding the pros and cons of every tile available in the market also helps to choose the best bathroom floor tile. Some of the top bathroom floor tiles are: Vinyl Tiles Ceramic Tiles Porcelain Tiles Stone Tiles Glass Tiles Linoleum Floor Tiles Cork Tiles 1. Vinyl Tiles Vinyl tile flooring for the bathroom is the most common and economical bathroom flooring option. It suits every bathroom type and gains a high degree of practicality. This floor tile is easily installed and provides excellent aesthetics. It is a popular choice when the client’s requirement is safety, durability and comfort.

  How to Inspect a Structure Using Acoustic Emission Testing? Acoustic emission (AE) is defined as the physical phenomenon in which a material generates elastic waves when subjected to stress or deformation. These signals are registered using a non-destructive test method (NDT) called the acoustic emission test. An acoustic emission test is conducted to monitor a member’s structural health to assess its retrofitting and repairing possibilities. Acoustic emission testing is an NDT method with widespread application in structural integrity test, monitoring bridges, pipelines, wind turbines, and leak detection. This article explores the principle and features of acoustics emission testing in construction. Principle of Acoustic Emission Test An acoustic emission test locates the yield point of the material by representing cracks, fractures, leakage points, or similar problems. The yield point is responsible for the generation of stress waves that propagate through the structure. The waves

  Passive House: Reduce Energy Consumption in Your Building Passive house is a concept used in construction to build energy-efficient, comfortable, and ecological buildings that are also affordable. It is a building standard that consists of a set of design principles that are used to achieve a precise level of energy efficiency within a specific level of comfort. Passive houses make effective use of the sun, internal heat sources, and heat recovery, due to which typical heating systems are not required even during the coldest times of the year. They also make use of some cooling techniques like strategic shading during summer to keep the temperature within comfortable limits. The concept and physics behind building a passive house   is the same all over the world, but the specific elements require adaptation in accordance with the climate of the region. Principles of Passive House Design The following five principles are fundamental to passive house design and construction: 1. Insulat
