Solar Roadways: Purpose, Construction and Applications Solar Roadway: Solar Roadway is a major term when it comes to construction. It is a street surface that generates electricity. The solar roadways comprise the glass layer, electronic layer, and base plate. The construction stage involves the wiring and furnishing of the base plate first. Then the layers get placed properly, and after that, the connection goes from the photovoltaic cells to the layers that get placed earlier. However, solar roadways are not for heavy automobiles. It is because heavy automobiles cannot resist heavy loads. Components of the solar roadways  As you know that the solar roadways have three broad layers. It includes the glass layers, electronic layers, and the base plate layer.  Glass layer This layer is the upper part of the solar roadway. This is the part where all the minimal-weight vehicles and the bicycles move. The glass layer in the solar roadway must have good durability. Further, it should also h

  How to Make Concrete Floor Sl ip-Resistant There are various types of finishes that you can adopt to make freshly poured concrete steps safer. 1. Better Concrete Most importantly, if at all possible, try to focus on laying down the best quality concrete possible so you don’t have to rely as heavily on a sealer to avoid a slip. Even a thin layer of good sealer can be enough to prevent an accidental slip in your home if the concrete is durable and the paint job is thorough. A thin layer of sealer will also keep plastic from accumulating, which will reduce the amount of decorative sealer and grit additives you need to apply to your concrete surface. Keep in mind that you’re using the sealer to strengthen your concrete, and make sure that the sealer does not cause the concrete’s weakness. 2. Anti–Slip Sealer The first option is to use a slip-resistant sealer. You can use penetrative sealers, which work beneath the surface rather than changing the texture of the surface.

  Carbon Fiber for Building Projects Carbon fiber is one of the most popular newer building materials. It is usually combined with other substances to form a composite material. Carbon fiber has become a go-to product because of its many advantages over traditional materials, including a high strength and low weight.   What is carbon fiber? Carbon fiber  (CF) consists of very thin strands of the element  carbon . Each strand is 5-10 microns in diameter, similar to the size of a spider’s silk. The amount of carbon in the fiber and its orientation will determine its physical properties. Carbon fibers have a very high tensile strength and low weight. Depending on the purpose of the end product, the fibers may be combined with metals, glass, or other materials. When combined with other materials, a binding matrix is used. Epoxy, vinyl, polyester, nylon and other additives may form the matrix.      What are the advantages of carbon fiber? Carbon fiber has many advantages ove

Rooftop Garden The rooftop garden is a garden on the roof of a house, apartment, or flat. There are various advantages of having a garden on your rooftop by planting trees and growing vegetables. It will also help in controlling the building temperature, architectural enhancement, recreational opportunities, habitats or corridors for wildlife, hydrological benefits, etc. While you create gardens at your rooftop, you can plant only plant trees in the pots and containers. The rooftops that are built with wood may not support an extra load of the pots and soil. However, gardening can be done for small plants. If the rooftop floor is made of concrete, then there will be less damage to the surface. Still, you have to use lightweight containers. Merits Of Having A Rooftop Garden It will reduce CO 2 emissions. It produces more oxygen. It will lessen the heat of building and energy costs. It will create a habitat for wildlife. It will capture and harvest rainwater. It reduces ambient temperat

  History of Heron’s Formula Hero of Alexandria  was a great mathematician who derived the formula for the calculation of the area of a triangle using the length of all three sides.   He also extended this idea to find the area of quadrilateral and also higher-order polygons. Heron’s Formula for Triangles According to Heron, we can find the area of any given triangle, whether it is a scalene, isosceles or equilateral, by using the formula, provided the sides of the triangle. Suppose, a triangle ABC, whose sides are a, b and c, respectively. Thus, the area of a triangle can be given by;                                     When do we use Heron’s formula Heron’s formula is used to find the area of a triangle when all its three side-lengths are known to us How to Find the Area Using Heron’s Formula To find the area of a triangle using Heron’s formula, we have to follow two steps: Find the perimeter of the given triangle Then, find the value of the semi-per

Transparent Concrete, Materials, Use, Advantages & Disadvantages of Transparent Concrete Transparent concrete may be defined as hardened concrete that permits passing light through it. It is also named light-transmitting concrete or translucent concrete. Transparent concrete increases the aesthetic beauty of the building so, it is popular in recent times. At nighttime, the light-transmitting concrete is more decorative, the light of the moon passing through the concrete to your rooms. Transparent concrete is similar to ordinary concrete because the strength of both concrete is the same. Generally, the internal wall is made by the use of transparent concrete. But, it is not commonly used for external walls because it may interfere with your privacy.   Materials Used In Transparent Concrete     Transparent concrete is manufactured by using a combination of fiber optics and fine concrete. These fibers turn into concrete-like other aggregates. These optical fibers can pass light from n

Application of Remote Sensing     There are various applications of remote sensing which may be grouped into the following: Resource Exploration Environmental Study Land use Site Investigation Archaeological Investigation Natural Hazards Study Resource Exploration: Geologists use remote sensing to study the formation of sedimentary rocks and identify deposits of various minerals, detect oil fields and identify underground storage of water. Remote sensing is used for identifying potential fishing zone, coral reef mapping and to find other wealth from ocean. Environmental Study: Remote sensing is used to study cloud motion and predict rains. With satellite data it is possible to study water discharge from various industries to find out dispersion and harmful effects, if any, on living animals. Oil spillage and oil slicks can be studied using remote sensing.   Land Use: By remote sensing, mapping of larger areas is possible in short time. Forest area, agri

Derivation of D 2 /162 in Steel Weight Calculation D 2 /162 is the first formula we ever learn in the construction industry. We know it is used to calculate the weight of steel bars. Also, know the importance of estimation in the Bar Bending Schedule. Here we are going to discuss the derivation of this formula. Derivation of D 2 /162   We know, Weight = Volume X Density To find out the weight of steel, Weight of steel per metre = Area of Steel X Density of Steel X Length of Steel We know that  The unit weight of steel is 7850 Kg/m 3 . Area of steel (circular shape) = πr 2 or πD 2 /4 So, Weight of Steel per metre =  Area of Steel X Density of Steel X Length of Steel = πD 2 /4 x 7850 x 1m = 3.14 x (D 2 / 4) x 7850 x 1m When multiplying all values should have the same unit. Here diameter is in mm and unit weight is in m 3 . 1 mm = 1/1000 m ; 1 mm 2 = 1/(1000) 2 mm 2 = 3.14 x (D 2 / 4) x 1/(1000) 2 x 7850 = D 2 x 6162.5 x 1/(1000) 2 = D 2 X (0.006162) = D 2 X 1/(0.006162) -1 = D 2

    Encumbrance Certification   When you buy a property, it is very important to check if there are any legal complications associated with it. Encumbrance Certificate (EC)  will help you find out if there are any charges created on the property. What is an Encumbrance Certificate? An  Encumbrance Certificate  is a legal document which will help you find out if there are any charges made on the property – financial or legal. You can avail an EC by visiting the respective Sub-Registrar's Office. Why is an Encumbrance Certificate Required? Before buying a property, you must ensure that the property has a clear title. Getting an Encumbrance Certificate will assure you that the property you wish to buy is free from such financial or legal liability. If you notice a charge on the EC, it is important to rectify it before you make the purchase. It will also help you find out if there are any existing owners who can legally claim the property. Apart from that, if you are pl
