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।

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...

Concrete Mix Design

Concrete Mix Design Concrete mix design is the method of optimally dosing various components of concrete,such as cement, aggregates, water,and additives, to make concrete less costly and will have specific  workability and homogeneity properties in the fresh state and strength and durability in the hardened state. Purpose of concrete mixes The main objective of the dosage of concrete mixes is to make a concrete that has the following characteristics: 1. Satisfy viability requirements in terms of drop to facilitate placement and consolidation. 2. Meets resistance requirements. 3.  Can be mixed, transported, placed and compacted efficiently. 4. Economical to manufacture. 5. Meets durability requirements to withstand the environment in which the structure is expected to serve Mixing ratio procedure Step 1. Calculate the target average compressive strength for the mixing ratio: The target 28-day average compressive strength according to clause 3.2 of IS 10262. ft = fck + 1.65...

Column

Column.  A column may be defined as an isolated vertical load bearing member the width of which is neither less than its thickness nor more than four times its thickness. Pier is a vertical load bearing member similar to a column except that it is bonded into load beating wall at the sides to form an integral part and extends to full height of the wall. A pier is introduced to increase the stiffness of the wall to carry additional load or to carry vertical concentrated load. Pier also strengthens the wall to resist lateral pressure without buckling. a supporting pillar especially : one consisting of a usually round shaft, a capital, and a base a colonnade of marble columns. something resembling a  column  in form, position, or function a  column  of water columns of smoke. The  row  is an order in which people, objects or figures are placed alongside or in a straight line. A vertical division of facts, figures or any other details based on category, ...
