One requires various kinds of construction materials in Bangalore for building a new House. These materials should be procured as per the size of construction. Construction materials should be well-integrated so that you will derive maximum benefit without any issues. One should know where you get materials from and how to manage them properly. If you have read through the detailed mentioned below, One can save a lot of time and money. The construction can take place in a hassle-free environment once you understand these materials and where they are used in building your Dream home.
Materials required for construction will be mentioned in the designing stage when professionally planned by an Architect who provides a detailed BOQ’s for construction. Structural materials required for construction are based upon the type of construction method applied. The material requirement might change during the construction stage. Proper planning should be done so that you will procure materials from right location and at right time.
Like Ready mix concrete is very much required for foundation irrespective of the type of construction that takes place. If you go for insulated concrete forms, you will need large quantity of concrete and a pump as well. Majority of building supplies from walling to roofing can be procured from the local merchant. If you go for ‘off site’ construction method, most of the materials will be supplied by a specialist manufacturer.
Various kinds of natural as well as man-made Building materials are used in the construction process. Natural materials include rocks, sand, clay, m sand, plaster sand and wood. These building materials required for construction process is categorized as per the trade such as carpentry, plumbing, civil works, plastering and roofing. The quality of soil will play an important role in the construction process. Larger amounts of clay will be used in the adobe style building and lower amounts of soil is used in sod building. Sand and gravel are other important materials which are used in the construction process. To create walls, rammed earth will be used. In order to increase the strength of walls, forms and pneumatic compressors are used in the building construction.
Rock is a very dense material and it offers great protection. The only drawback associated with rocks is that they are very heavy and does not deliver impressive look. Stone buildings and stone walls were built from time immemorial. There are some civilizations which built constructions based on stone only. The Egyptian pyramids are best example in this context.
Cement is nothing but a binder. It will harden itself or bind together with other materials. There are cements which harden continuously because of exposure to the water content. Portland cement will harden because of hydration and chemical reactions that take place because of the presence of moisture. In order to retain strength, non-hydraulic cements such as lime and gypsum plaster are used.
They should be kept dry so that they will retain strength without any issue. Portland cement is available in different grades. The selection of the cement should be done based on its compression strength. High grade cement is used in the construction of residential as well as commercial buildings.
CHEMICAL Composition of CEMENT
60% to 70% – LIME (CaO)
20% to 25% – SILICA (SiO2)
5% to 10% – ALUMINIA (Al2O3)
2% to 3% – FERRIC OXIDE (Fe2O3)
What is 43 Grade CEMENT?
Ordinary Portland cement (OPC) is available in grades such as 33, 43 and 53. The compression strength of cement concrete after 28 days of setting will be measured to certify the cement grade. If you go for 43 grade cement, you will get compression strength of 43 mpa (mega pascals) in 28 days. 43 grade cement is used in general civil engineering construction work. Plastering, pointing, flooring, brick masonry and RCC work will be done very efficiently with 43 grade cement. The design strength of 43 grade cement will be of the order of 430 kg/sq cm.
The drawback with 43 grade cement is that it will attain strength slowly. However, it will attain the same strength that is attained with 53 grade cement after sometime. The hydration process in 43 grade cement will be slow. The heat release will be very less. Proper care should be taken to avoid micro-cracking. Ordinary and small scale consumers can go for 33 grade of cement also as per their needs.
What is 53 Grade CEMENT?
If you go for 53 grade cement, you will get compression strength of 53 mpa (mega pascals) in 28 days. 53 grade cement is available in ordinary mode as well as in special mode. If the initial strength is to be achieved very quickly, it is required to go for 53 grade cement. The construction pace will be very fast with 53 grade cement.
It is used for fast setting. The strength attained in 7 days will be 27 mpa with 53 grade whereas the strength attained with 43 grade will be just 23 mpa in 7 days. The initial higher strength is the criteria with 53 grade OPC and it is commonly used for plastering works. It is used in RCC and pre-stressed concrete of higher grades. The cost of 53 grade cement is higher than 43 grade cement and it will be of the order of 2% to 3%.
The structural framework of high-rise buildings is done by metal. It is used as an external surface covering element. Steel is the most common element used in structural building materials. It is very strong and can be treated to deliver long-lasting results. As corrosion is the main enemy of steel, alternative materials are used for other purposes.
Alloys used to Prepare Steel/ TMT Bars
Aluminum alloys are light in weight and they offer better corrosion resistance properties.There are many pre-fabricated structures which are used for this purpose. Expensive materials are used for specific purposes. They enhance the beauty of your home in a very efficient way.
How are TMT Bars Manufactured..?
When work hardening and heat-treatment is integrated into a single process, it is called as thermo-mechanical process. If bars are treated in this process, they are called as TMT bars. The applications of TMT bars include rebar steel.
The process is intended to enhance the strength of low-carbon steel in an inexpensive way. The surface layer of the bar will be quenched. In this process, the deformation of crystal structure will take place and intermediate layers will be pressurized. At the same time, quenched layers will be tempered using the heat available from the core.
The outer surface of TMT bars will be very hard and the inner core will be very soft. As part of the manufacturing process, hot rolled steel wires will go through water as well. The weld-ability of the product improves and corrosion resistance will also improve in this process. As outer surface of the metal will be cooled at a much faster pace than the core of the metal, there will be great temperature gradient from the bar axis to the periphery. The residual stress in TMT bars will be lesser than HYSD (High Yield Strength Deformed) Bars. The corrosion resistance is also very high. The ductility of TMT bars is higher than similar strength grade of bars.
Difference Between TMT Bars and Twisted Bars..?
There is difference between twisted bars and TMT bars. Twisted bars refer to cold treated bars and TMT bars refer to hot treated bars. TMT bars will go through three stages of processing. They are quenching, self tempering and atmospheric cooling. As there will not be any twisting during the TMT process, no torsional stress takes place. Hence, there will not be any surface defects in TMT bars. TMT bars have martensite micro structure. Hence, the tensile strength will be higher than twisted bars.
Superior bend properties, better elongation, fire resistance, high fatigue resistance and good weldability & formability are some of the factors which make it an ideal choice in the construction industry. Hence, TMT products are used in the construction of bridges, dams, structures, high-rise buildings, concrete reinforcement and underground platforms.
There are various kinds of bricks in the market. They are used as per the application. Bricks available in the market are categorized under various headings. There are unburnt (sun-dried) bricks and burnt bricks. If the construction is done on temporary basis, you can go for unburnt bricks. If the structure is exposed to heavy rains, it will be damaged.
Different Types of Bricks.?
The brick-mould will be burnt inside the factory and these are very commonly used in the construction. They are classified into four types: first class, second class, third class and fourth class bricks. There are bricks available in various shapes.
These shapes include bullnose brick, channel brick, coping brick, cownose brick, curved sector bricks, hollow bricks, paving bricks, perforated bricks and purpose-made bricks. Bricks used by masonry are also categorized as common burnt clay bricks, sand-lime bricks, engineering bricks, concrete bricks and fly ash clay bricks.
How BRICKS are Manufactured..?
Bricks manufactured at extremely high temperatures are termed as engineering bricks. A very dense and strong brick will be formed so that the strength is very much enhanced and water absorption will be limited. In addition to damp-proof characteristics, there will be excellent load bearing capacity with engineering bricks.
You will get protection from heat and cold by installing highly efficient bricks at home. Natural bricks are made in various colors. It is possible to achieve various textures in a very efficient way. You can take advantage of excellent compression strength offered by bricks. Bricks should have the capability to release as well as absorb moisture in a very efficient way. the humidity as well as temperature should be well-regulated.
