Reinforced Cement Concrete RCC

Define reinforced concrete.

 Reinforced cement concrete is a composite material is made of concrete and steel reinforcement. The concrete may be assumed to work purely in compression whereas the reinforcement is predominately subjected to tension. For a large range of applications it is sufficient to consider the uni-axial response of either material.
Reinforced concreteconcrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure.
What is reinforced concrete used for? Reinforced concrete is used for construction on a large scale, such as bridges, dams, piers, tall buildings and stadiums. It is most commonly used in domestic construction for the footings and foundations of smaller everyday dwellings.
There are four types of reinforcement: positive, negative, punishment, and extinction. We'll discuss each of these and give examples. Positive Reinforcement. The examples above describe what is referred to as positive reinforcement.

The purpose of using reinforced cement concrete.

 > Plain cement concrete has very low tensile strength. The tensile strength of concrete is about one-tenth of its compressive strength. As a result, a plain concrete beam fails suddenly as soon as the tension cracks start to develop. 
> To improve the tensile strength of concrete, some sort of reinforcement is needed which can take up the tensile stress developed in the structure. 
> It's not only increases the strength but also in preventing the temperature and shrinkage. 
> Therefore, reinforcing steel is added in the tension zone to cary all the developed tensile stresses.

प्रबलित कंक्रीट को परिभाषित करें।
 प्रबलित सीमेंट कंक्रीट एक मिश्रित सामग्री है जो कंक्रीट और स्टील के सुदृढीकरण से बना है। कंक्रीट को पूरी तरह से संपीड़न में काम करने के लिए माना जा सकता है, जबकि सुदृढीकरण मुख्य रूप से तनाव के अधीन है। अनुप्रयोगों की एक बड़ी रेंज के लिए यह किसी भी सामग्री की यूनी-अक्षीय प्रतिक्रिया पर विचार करने के लिए पर्याप्त है।
प्रबलित कंक्रीट, कंक्रीट जिसमें स्टील को इस तरह से एम्बेडेड किया जाता है कि दो सामग्रियां एक साथ बलों का सामना करने में कार्य करती हैं। प्रबलिंग स्टील-छड़, बार या जाल-तन्यता, कतरनी और कभी-कभी एक ठोस संरचना में संकुचित तनाव को अवशोषित करता है।
प्रबलित कंक्रीट का उपयोग किसके लिए किया जाता है? प्रबलित कंक्रीट का उपयोग बड़े पैमाने पर निर्माण के लिए किया जाता है, जैसे कि पुल, बांध, शिखर, ऊंची इमारतें और स्टेडियम। इसका उपयोग सामान्य रूप से छोटे रोजमर्रा के आवासों के फुटिंग और नींव के लिए घरेलू निर्माण में किया जाता है।
सुदृढीकरण चार प्रकार के होते हैं: सकारात्मक, नकारात्मक, दंड और विलुप्त होने। हम इनमें से प्रत्येक पर चर्चा करेंगे और उदाहरण देंगे। सकारात्मक सुदृढीकरण। ऊपर दिए गए उदाहरण बताते हैं कि सकारात्मक सुदृढीकरण के रूप में क्या संदर्भित है।

प्रबलित सीमेंट कंक्रीट का उपयोग करने का उद्देश्य।
 > सादे सीमेंट कंक्रीट में बहुत कम तन्यता है। कंक्रीट की तन्यता ताकत इसकी संपीड़ित ताकत का लगभग दसवां हिस्सा है। नतीजतन, एक सादा कंक्रीट बीम अचानक से विफल हो जाता है जैसे ही तनाव दरारें विकसित होने लगती हैं।
> कंक्रीट की तन्यता ताकत में सुधार करने के लिए, किसी प्रकार के सुदृढीकरण की आवश्यकता होती है जो संरचना में विकसित तन्यता तनाव को उठा सकती है।
> यह न केवल ताकत बढ़ाता है, बल्कि तापमान और संकोचन को भी रोकता है।
> इसलिए, सभी विकसित तन्यता तनावों को रोकने के लिए तनाव क्षेत्र में मजबूत स्टील को जोड़ा जाता है।

MAKE A GREEN BUILDING.

What is a Green Building? Procrastinate no longer. The time to build your green and sustainable home is now. Like so many of us, you may have been sitting back and dreaming about building a new home so that it perfectly meshes with the environment. It would be a home that is as eco-friendly and green as it is cozy, functional, and smart to live in. This can be done and the time  can be  now. No longer is it necessary to compromise comfort in order to be environmentally conscious. Because our world is rapidly changing, often in ways that are less than desirable, it is up to each and every one of us to make positive changes. And those changes can begin in that one area we all have the most control over: our home. The concept of a green building was developed in the 1970s in response to the energy crisis and  people’s growing concerns about the environment. A Green Building, also known as a sustainable building , is a structure that is designed, built, renovated, o...

MACHINE FOUNDATION.

MACHINE FOUNDATION. The design of machine foundation involves careful study of the vibration characteristics of the foundation system. Relevant data for the design and construction of the foundation of machine should be obtained from the manufacturer of the machine , prior to the start design.  All parts of machine foundation should be designed for maxim stresses due to the worst combination of vertical loads, torque, longitudinal and transverse forces, stresses due to temperature variation and the foundation dead load. In case, the foundation layout is partly built up of beam and column construction , straight bars should be provided both at top and bottom of the beams and the spacing of the stirrups should be close. The main foundation block should have the designed thickness and should be reinforced both at top and bottom even if the reinforcements are not required from design considerations. Machine foundations  are special types of  foundations  required fo...

Medlum Density Fibre Board (MDF)

Medium Density Fibre Board (MDF)  MDF IS made from wood and other lignocellulose material refined into fibres and reconstituted with a resin binder. Row wood material is normally a single species wood. MDF has homogeneous structure with uniform density, texture and properties throughout, no identifiable grain can be seen at edge, end or face. There are no internal voids or pits and there is no variation in the surface hardness. Unlike plywood MDF doesn't delaminate. It has much higher strength than particle board. Since edges are totally smooth and uniform, costly tipping or beading with strips of wood required for plywood and particle board is not essential. It can be carved, grooved or embossed just like any timber. The surface of MDF is totally smooth and accepts all kinds of finishes - paints, varnishes and laminates. One such type of famous board in the market is 'Duratuff" . It comes in both interior and exterior grade. Duratuff prelaminated boards are also avail...
