Lightweight concrete is a special type of concrete made of lightweight coarse aggregate. Sometimes lightweight fine aggregate is used instead of lightweight coarse aggregate. The density of lightweight concrete is 1440 to 1840 kg/m³. Lightweight concrete is made by using lightweight aggregates or low-density materials such as volcanic pumice, clay, slate, shale, scoria, tuff. If the density of … Read more

The dog-legged staircase consists of two flights in opposite directions. In this type of staircase, a flight of stairs ascends to a half-landing before turning at a right angle and continuing upwards. Its sectional elevation looks like a dog. The development of the Dogleg Stairs is practical in view of its compact plan. The flight of stairs uses the space given. It … Read more
In this article, I will describe prismatic channels and non-prismatic channels. These two channels are considered open channels. Let’s get started. First, we will know about prismatic channels. What are Prismatic Channels? Prismatic channels have a uniform cross-section throughout the channel length and constant bottom slope. Prismatic channels can be triangular, rectangular, parabolic, trapezoidal, or … Read more
California Bearing Ratio test or CBR is used to calculate the strength of the material for pavement design. CBR test is the test that was developed by the California state highway department of the USA for the determination of subgrade strength of highway and air-filled pavement. It is a penetration test. In this test, a … Read more

The reinforced concrete beam which is constructed on the ground level is known as the grade beam. Mostly it is used to connect pile caps in pile foundation. The functions of a grade beam are very different from a wall footing because a grade beam is designed for bending. A grade beam is normally a … Read more
Floor Space Index (FSI), is the ratio of the total floor area of a structure (Built-up area) to the total Plot area (land). Floor Space Index (FSI) is also known as Floor Area Ratio (FAR). This numeric value of the Floor Space Index addresses the total amount of area (on all floors) you can build … Read more
Wien’s Law, named after the German Physicist Wilhelm Wien, discloses to us that objects of various temperatures transmit spectra that top at various frequencies. More sizzling radiations transmit radiations of more limited frequency and henceforth they seem blue. Essentially, cooler radiations discharge radiations of longer frequency and thus they seem ruddy. In this short piece … Read more
There are 3 laws discovered by Kepler. These empirical laws are known as Kepler’s laws of planetary motion. The elliptical orbits of planets were represented by calculations of the orbit of Mars. From this, Kepler describes that different bodies in the Solar System, including those who are very away from the Sun, also have elliptical … Read more
