From the previous blog Part-I of this series, the concept of underwater concreting and how it became the preferred concreting method for construct structures whose foundation is laid on water. The main advantage of underwater concreting is that it prevents the issues of washout by the addition of addictive components.
With the emergence of better technologies, techniques for underwater concreting has become innovative and has led to the discovery of better methods which will be explained in the following section.
We all know that concrete is the vital material needed for the construction of any man-made structures. Without concrete, literally, no construction of buildings, bridges, dams and other structures etc is possible. Concrete is known for its incredible compressive strength.
Normally concrete is used in constructing buildings whose foundations are built on the land but during the construction of structures like bridges, dams etc, the foundation part of the structure lies underwater, therefore in these cases, underwater construction is the only possible method.
When it comes to bridges or any other man-made structures like buildings, they all have an estimated lifetime after which they start to show signs of wear and tear. However, the signs can be delayed for much longer if the structure is given proper periodic maintenance and the construction of the structure using quality materials.
With the emergence of innovative ways and materials in the construction field, it is currently possible to build structures that are more strong and durable than the ones constructed long before. But even the newly constructed structures are collapsing after or during the construction phase but some of the old ones still stand intact, therefore, this raises a question about the integrity of the structure.
Steel is an indispensable part of construction. The possibilities presented by steel in the field of construction is not just limited to steel sections, but also as steel bars as reinforcement to cement concrete in construction of structures. The story of steel as a reinforcement presents a picture of innovation in the field of construction. Starting as iron as reinforcement to structures, to highly ductile mild steel to deformed bars (High yield strength deformed bars) and finally to thermo mechanically treated (TMT) steel bars, showcase an evolution of steel reinforcements to keep up with the needs presented by humans in the field of construction.
Corruption in both public and private undertakings is not an unusual or uncommon scenario for a resident in a country like India. The dangers of corruption for unlawful gains have lead to disaster, of which collapse ——– was discussed in —- blog. But ever wonder why not every structure or construct you have known where corruption has eaten up quality is still functioning as its supposed to. It’s not just God’s grace, but a large part of its credit goes to the Engineer who made the plans and necessary load calculations for the construct. So why do they make such calculations. On planning structures, an engineer has to calculate structural load which comprises of both dead loads and live loads acting on it, and also the environment loads and much more. This is so especially in cases of bridges and structures where live loads are more prominent. In this blog we will be discussing more on how loads are calculated for buildings.
Cyclone, as described by the meteorology is a large scale air mass that rotates around a strong centre of low atmospheric pressure. Well, so is typhoons and hurricanes. Cyclones, typhoons and hurricanes are the same phenomenon, but are known differently in different parts of the world. With Odisha in the wake of a massive cyclone Fani and the world in discussion of the recurring and ever strengthening cyclones observed around the world as a man made disaster in the era of ‘humans’, let’s talk on how to build to survive the cyclones and not just let our homes be another matchstick on fire.
The construction of buildings is quite innovating and are truly a marvel. When we compare the current timeline with the ancient timeline, we can see that the number of buildings has risen tremendously over the centuries. With time, different types of innovations in constructions were introduced. This resulted in the construction of better, stronger and taller buildings that are safe to live in.
Part-I of this three series blog described a whole lot about construction and the history of various materials used for constructing buildings. Most importantly it described two major components used for constructing buildings and also a comparison between them which were stone and bricks. Stones, in fact, as described in the first blog has been currently replaced by bricks. Although stone masonry had its advantages, what made it less preferred in the construction of buildings is the complex work involved in crafting structures using it, but we have to admit that the buildings and monuments crafted using stones surely gives a unique aesthetic beauty and appeal.
We see structures going up everyday, but do we realize the effort behind it. Construction requires great commitment, resources and technical skills. When it comes to resources, we are familiar with the construction materials such as Bricks, Concrete, Reinforced steel and such. When we look at the history of the construction, we have come a long way from using stones to bricks to different variations of bricks. In any construction, the most needed component apart from concrete and steel are bricks, obviously.
Summer season is all over us. The temperatures are soaring high all across India, marking the arrival of the summer season in full force. The temperature has crossed 40°C in many areas. Also similar to the rising temperature, another thing that is also rising is the construction of buildings. As we know excessive heat is not good for the people involved in the construction, well it is the same case for the buildings. More specifically, the setting of concrete.
