Reinforced cement concrete (RCC)

We will discuss and learn about reinforced cement concrete here in this article. We also call reinforced cement concrete RCC in short form. And the RCC we are discussing here is the combination of reinforcement and concrete. The concrete we make from the cement.

RCC is a very uncertain material. It needs very precise design proportions so that it can maintain structural integrity and safety. In this article, we will discuss the basic design philosophy which we use to design the RCC. To understand RCC it is important to know about the ingredients which we used to prepare the concrete. We will also discuss the design steps and design examples.

Basic mechanism of RCC

In the reinforced cement concrete the concrete takes the compression and the reinforcement in the RCC takes care of tension. As concrete is good in tension and reinforcement is good in tension. The concrete is poor in the tension which we can see from the stress-strain curve of the concrete. Similarly, the mild steel reinforcement we use in the RCC is good for tension and compression both. Although here we are using it for the tension only.

Material used to make reinforced cement concrete

To understand the RCC completely it is very important to understand about the constituents materials. T

The following materials are used to make concrete:

  • Cement: It is the binder material in the concrete. Although we use cement in RCC in a very small fraction, it affects the properties of RCC very dominantly. We study different properties of cement like initial and final setting time, compressive strength through cubes,
  • Water: The water-cement ratio is the most important parameter which decides the strength of cement. Actually, the binding properties of cement come after hydration. Hence the amount of water becomes very important.
  • Sand: It is also known as fine aggregate. It acts as filler material in the concrete. It fills the voids of the coarse aggregates.
  • Coarse aggregates: The coarse aggregates are the main body of the concrete. It provides the main strength to the concrete. The size and shape of the coarse aggregate affect the workability of the concrete.
  • Admixture:

The chemical properties of the above material is not so important for the RCC design rather we will consider the physical properties of the materials. The main focus in this subject will be to discuss the physical behaviour of the concrete and reinforcement.

Basic design philosophy of RCC

In this category, we will discuss the basic philosophy to design the RCC. In this section, we will cover only the mechanics part of the RCC. We will try to understand how this RCC beam takes the load. How the concrete transfer the load to reinforcement.

In this section we will cover following topics:

Under this topic, we will not see how to design the members. Our focus in this section will be to analyse the section behaviour of the RCC members.

Design steps of different RCC members

After learning the basic behavioural philosophy we will now see how to design the members. In this section, our main focus will be to learn the steps to design the members.

In this section, we learn the basic design steps and design examples of the following members:

  • Design of one way slab | Steps | Example
  • Design of two-way slab | Steps | Example
  • Design of staircase | Steps | Example
  • Design of singly reinforced beam | Steps | Example
  • Design of doubly reinforced beam | Steps | Example
  • Design of column | Steps | Example
  • Design of footing | Steps | Example
  • Design of deep (pile) foundations | Types | Steps |Construction

Complete G+3 building design

In this section, we will learn the complete design of the G+3 building. The articles we covered in the previous section were taking hypothetical load cases. In this section, we will see everything like a real-life problem.

The G+3 building will be analysed and designed with hand calculations. After that detailed steps were discussed to understand the software behind the scene.

We will cover the above G+3 building in the following articles:

  • Preliminary positioning and sizing of rooms
  • Positioning and orientation of the column
  • Making drawings and column plans
  • Analysis of G+3 building
  • Grouping and marking of slabs, beam, and columns
  • Calculation of loads and final factored load
