  Underwater Construction Welcome back to Civil Adda  Hi friends,  So far we have discussed many interesting topics.   In the today's post of  Civil Adda  we are going to learn about something that is related to constructions, constructions that are carried out in water.  Have you ever thought of how constructions are carried out in the water? like that of bridges, dams etc.,  How foundations are laid in water?  And what are the problems that are posed by water during construction work?   All such interesting things are going to be discussed in this post of Underwater Construction .  So at first what is Underwater Construction?      As we all know any construction that is laid in water comes under underwater construction, it may be a tunnel, a bridge, dams or some other. As we think of a construction, concrete, foundations, construction technology etc., are some of the aspects that come to our mind. And so we are going to deal about all

Hello friends, Welcome back to Civil Adda Before learning about our today's interesting topic, let me pose some questions for you. 1.What is the tallest building built by man so far?      Offcourse you would say it as Burj Khalifa. ..that's a pretty simple question :D 2.Now my question to you is, have you ever thought of how the top most storeys are built? 3.What type of building materials are used for such tall constructions? 4.Do you know that there is a relation between Einstei n's Theory of Relativity and  tall buildings and our age ? Yeah, in the today's topic we are going to discuss all about these interesting things as a part of today's topic Skyscrapers. So what does this word skyscrapers do refer to ?

Ancient Construction Techniques Hello friends, You all might have seen many ancient construction wonders like  Pyramids of Egypt, Forbidden City of China, Great Wall of China, Angkor wat etc... But have you ever thought of how such massive blocks of stones are moved or lifted to the construction site? Yeah, in the today's post we are going to discuss some such interesting techniques used by our ancient engineers.let us head to the topic. Forbidden City   As a matter of fact, the construction work of Forbidden City took 14 years to get completed.Some of the stones used for this construction weighs hundreds of tons which were quarried from the nearby quarry which is 70km away. So the question we are getting is how did they move them to construction site from the quarry? For this, the engineers of those times devised many plans. One of the down to earth technique is ice lubrication .During winters they use to lubricate the ice roads with water.Whic

IS CONCRETE A GOOD CHOICE?                                               So far we have seen one face of concrete that is concrete as a good choice of building material.In this post, we are going to know about the other side too... The substance that is consumed mostly on the earth after water is  concrete. Yet, like any other material it too have some disadvantages... So we are going to deal with some such interesting facts about concrete in this post. Before jumping into our topic... Let me have some questions for you ... 1. Which is the most used building material in the world? 2. Which contributes to the production of the major amount of co2  a green house gas? If your answer to the first question is concrete and you are unaware of the answer for the second one, then you'll be surely surprised to hear that it too gets the same answer. Some of the main areas that are to be discussed while dealing with impacts of concrete are stated below. Concrete -a CO2 cont

Ya, then you are at the right place.Here we go. transit_mixer_carrying_RMC Let us think about this situation when some transit mixer transporting RMC gets stuck in the mid of traffic for a long time then what will be your remedy in avoiding concrete from getting set... yeah, this is the case where sugar comes in handy by acting as a retardant, making concrete more plastic.For your surprise, you can even add some sort of cold or soft drinks to the concrete for delaying the setting time of concrete. So, How does it work? There are diversified theories in explaining this 'sugar in concrete' concept. Some of the most signif
